I have a design where I use an IP module generated by Lattice Diamond. This uses the Macxo3l library which is shipped with diamond as a vendor library.
Using GHDL I can compile the design including this library using the instructions from https://ghdl.readthedocs.io/en/latest/building/PrecompileVendorPrimitives.html then the commands.
ghdl -i --ieee=synopsys -P=lattice/ --workdir=work cores/*.vhd
ghdl -i --workdir=work src/*.vhd
However I have been unable to make this compile using cocotb. Below is my make file. Where I use the command VHDL_SOURCES_Lib which I found reference to at https://cocotb.readthedocs.io/en/latest/building.html
TOPLEVEL_LANG ?= vhdl
PWD=$(shell pwd)
ifeq ($(OS),Msys)
WPWD=$(shell sh -c 'pwd -W')
PYTHONPATH := $(WPWD)/../model;$(PYTHONPATH)
else
WPWD=$(shell pwd)
PYTHONPATH := $(WPWD)/../model:$(PYTHONPATH)
endif
VHDL_SOURCES_Lib = $(WPWD)/../lattice/
VHDL_SOURCES = $(WPWD)/../cores/Adder.vhd $(WPWD)/../cores/Counter.vhd $(WPWD)/../cores/Multiplyer.vhd $(WPWD)/../cores/SinCos.vhd $(WPWD)/../src/top.vhd
TOPLEVEL := top
MODULE := test_of_top
include $(shell cocotb-config --makefiles)/Makefile.inc
include $(shell cocotb-config --makefiles)/Makefile.sim
Compiling this however gives me the error:
make results.xml
make[1]: Entering directory '/HDL/cocotbTest'
make[1]: *** No rule to make target '/HDL/cocotbTest/../cores/Adder.vhd', needed by 'analyse'. Stop.
make[1]: Leaving directory '/HDL/cocotbTest'
/home/anaconda3/lib/python3.6/site-packages/cocotb/share/makefiles/Makefile.sim:84: recipe for target 'sim' failed
make: *** [sim] Error 2
I am able to run the cocotb examples using GHDL. How should I instruct cocotb to include the Vendor Primitive files.
Thank you for any help you can provide.
I think you should add the exact filenames in VHDL_SOURCES_Lib as documentation said :
VHDL_SOURCES_lib
A list of the VHDL source files to include in the VHDL library lib (currently GHDL only).
But to add precompiled library as you show, you have to pass a compile option to ghdl : -P=lattice/
Use COMPILE_ARGS to add it:
COMPILE_ARGS=-P=lattice/

I am very much lost here and could really use some help.
I'm working on an Honours project for next year that involves a physics simulation using Bullet and Vulkan for rendering. After a few months of work I have most of the project functioning. It needs a lot of refactoring and cleaning which will be the next stage.
I have been using a makefile but wish to migrate to CMake for a few reasons. Mainly because it seems to be the standard and because I want to compile for different OS's in the future (I'm running Linux but may need to deploy on Windows or Mac). Finally, I was recompiling the whole project for even a small change, which was beginning to become a problem as I started Unit Testing more.
The old makefile is as follows :

I installed cmake using the latest install script for 3.21.0.
I created a CMakeLists.txt in the root of the project as follows :
cmake_minimum_required(VERSION 3.21.0)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17")
project(LanderSim)
file(GLOB_RECURSE SOURCES "src/**.cpp")
add_executable(main ${SOURCES})
find_package(Bullet CONFIG REQUIRED)
if (BULLET_FOUND)
include_directories(${BULLET_INCLUDE_DIRS})
target_link_libraries(main PRIVATE LinearMath Bullet3Common BulletDynamics BulletSoftBody)
endif (BULLET_FOUND)
After many hours of trying I decided to try vcpkg. Following the install instructions from bullet :
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
./vcpkg install bullet3
This resulted in errors of
CMake Error at CMakeLists.txt:11 (find_package):
Could not find a package configuration file provided by "Bullet" with any
of the following names: BulletConfig.cmake bullet-config.cmake
Looking in CMakeCache.txt i see "Bullet_DIR:PATH=Bullet_DIR-NOTFOUND"
I found the BulletConfig.make file in "/home/ash/vcpkg/installed/x64-linux/share/bullet3" and in "/home/ash/vcpkg/packages/bullet3_x64-linux/share/bullet3" and set the MakeCache.txt var Bullet_DIR:PATH to these variables (tested one at a time).
Running again I get CMake set_and_check() function not recognised. Or something to that effect. Looking in the BulletConfig.make file I see these set_and_check() functions aren't recognised by the linter. I cant find any information about them being deprecated online but I assume this is the case. So I change to set() and CMake then succeeds and builds its files.
Running make I then get an error.
fatal error: btBulletDynamicsCommon.h: No such file or directory,
#include <btBulletDynamicsCommon.h>
I tried prepending bullet/ to the include path as others had this issue but it causes the same error.
So I must be doing something wrong and I'm obviously not understanding the process that CMake uses to add includes and link libraries. I'm sure, given the popularity of CMake, that there must be something obvious. But I've spent about 10 hours over a few days searching and trying different variations and I'm starting to get very frustrated.
I've bounced off CMake before (hence why I was working with a makefile for months), but I'm determined to do this properly. I just could really use some help if anyone knows how to get CMake to generate a makefile that can see a package installed with vcpkg.
Or indeed if the vcpkg of Bullet is out of date, then a way to link and include it with CMake alone would be great. I just thought vcpkg would be easier as it provides a cleaner file structure by default as well as a CMake config file.
Thanks.
EDIT1
I've used 'cmake .' and 'cmake . -DCMAKE_TOOLCHAIN_FILE=/home/ash/vcpkg/scripts/buildsystems/vcpkg.cmake' to build the makefile. Both result in the same missing headers errors when calling make.
EDIT2
All CMake files were removed from the project (except CMakeLists.txt) before each call to cmake to ensure no values were stored there.
EDIT3
Poked around a bit more. Here is the BulletConfig.cmake file :
#
# BulletConfig.cmake(.in)
#
# Use the following variables to compile and link against Bullet:
# BULLET_FOUND - True if Bullet was found on your system
# BULLET_USE_FILE - The file making Bullet usable
# BULLET_DEFINITIONS - Definitions needed to build with Bullet
# BULLET_INCLUDE_DIR - Directory where Bullet-C-Api.h can be found
# BULLET_INCLUDE_DIRS - List of directories of Bullet and it's dependencies
# BULLET_LIBRARIES - List of libraries to link against Bullet library
# BULLET_LIBRARY_DIRS - List of directories containing Bullet' libraries
# BULLET_ROOT_DIR - The base directory of Bullet
# BULLET_VERSION_STRING - A human-readable string containing the version
set(PACKAGE_PREFIX_DIR /home/ash/installed/x64-linux)
set ( BULLET_FOUND 1 )
set ( BULLET_USE_FILE "${PACKAGE_PREFIX_DIR}/share/bullet3/UseBullet.cmake" )
set ( BULLET_DEFINITIONS "" )
set ( BULLET_INCLUDE_DIR "${PACKAGE_PREFIX_DIR}/include/bullet" )
set ( BULLET_INCLUDE_DIRS "${PACKAGE_PREFIX_DIR}/include/bullet" )
set ( BULLET_LIBRARIES "LinearMath;Bullet3Common;BulletInverseDynamics;BulletCollision;BulletDynamics;BulletSoftBody" )
set ( BULLET_LIBRARY_DIRS "${PACKAGE_PREFIX_DIR}/lib" )
set ( BULLET_ROOT_DIR "${PACKAGE_PREFIX_DIR}" )
set ( BULLET_VERSION_STRING "3.17" )
# Load targets
if(NOT TARGET Bullet3Common)
file(GLOB CONFIG_FILES "${PACKAGE_PREFIX_DIR}/share/bullet3/*Targets.cmake")
foreach(f ${CONFIG_FILES})
include(${f})
endforeach()
set(_DIR)
endif()
As stated before a few of the set functions were set_and_check(). So I changed to set() as apparently cmake 3.21 has no set_and_check() function. After a little testing by printing message(), i found that PACKAGE_PREFIX_DIR was not being set anywhere. So that is why I've set it explicitly in this file. The variables are now set correctly as reported by message() in the CMakeLists.txt file. But still it make cannot find the header files.
EDIT4
I created an empty project and ran through each library I wanted to include. Everything works except for Bullet3. However it does now see the header files. What changed between the two CMakeFiles? Nothing as far as I can tell. I'll need to find out because I have to port this project over but in the meantime this is another issue with the package.
from /home/ash/projects/C++/CMakeImportTests/src/main.cpp:22:
/home/ash/vcpkg/installed/x64-linux/include/bullet/BulletCollision/CollisionDispatch/btCollisionWorld.h:77:10:
fatal error: LinearMath/btVector3.h: No such file or directory
77 | #include "LinearMath/btVector3.h"
I think this is the same issue as described #7877
If i remove all includes of Bullet but leave the CMakeList.txt untouched, we get this error:
[ 50%] Building CXX object CMakeFiles/main.dir/src/main.cpp.o
[100%] Linking CXX executable main
/usr/bin/ld: cannot find -lLinearMath

make[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/main.dir/all] Error 2
make: *** [Makefile:91: all] Error 2
Is this a clue that some environment variable is not set?
EDIT5
There seems to be an ordering dependency for the target_link_library call. The suggested usage is:
target_link_libraries(main PRIVATE LinearMath Bullet3Common BulletDynamics BulletSoftBody)
Checking bullet.pc in the libs/ directory i found
Libs: -L${libdir} -lBulletSoftBody -lBulletDynamics -lBulletCollision -lLinearMath
So I tried rearranging and following the pattern:
target_link_libraries(main PRIVATE BulletSoftBody BulletDynamics BulletCollision Bullet3Common LinearMath)
Additionally there was also a need to manually link directories.
target_link_directories(main PRIVATE ${BULLET_LIBRARY_DIRS})
This now compiles without error in my test project. It seems LinearMath must be after most of the other libraries (although it can be before Bullet3Common it seems).
For some reason it's still not finding the header files when I copy the exact same CMake commands over to my main project. So I'm not free of this yet.
I should say that I was able to remove the change I made to BulletConfig.cmake of setting PACKAGE_PREFIX_DIR statically.
So just to recap my issue. A small test project works and I can use bullet and number of other libraries that I use in my main project. But if i copy this working CMakeLists.txt to my main project it can no longer find the headers and throws this error :
btBulletDynamicsCommon.h: No such file or directory
8 | #include <btBulletDynamicsCommon.h>
Bullet_DIR:PATH=/home/ash/vcpkg/installed/x64-linux/share/bullet3 is the same in both cases.
After all that.
The set_and_include() error is a known issue and mathisloge over at vcpkg git said the Bullet package needs to be updated. The workaround is to change the calls to set().
The ordering of the target libraries is important. The suggested way in the Bullet vcpkg package is :
target_link_libraries(main PRIVATE LinearMath Bullet3Common BulletDynamics BulletSoftBody)
But this fails to compile. It should be:
target_link_libraries(main PRIVATE BulletSoftBody BulletDynamics BulletCollision Bullet3Common LinearMath)
Also had to tell cmake the link directories using :
target_link_directories(main PRIVATE ${BULLET_LIBRARY_DIRS})
Then I still had header missing errors. But after a restart things just started working again. Hopefully there is enough here to help someone if they hit similar problems.
I'm pretty new to installing, rearranging files, and somewhat writing code on Linux. When tasked to install CLion along with SFML and CMake, I've come into a lot of problems figuring out how to make them work. I'm currently using a Debian GNU/Linux bullseye/sid(copied straight from what I saw), so if there's anything specific about that, that'd be nice to know too.
The problem in particular that I'm encountering is when I decide to run my file. I get these set of errors.
/usr/bin/ld: attempted static link of dynamic object `/home/user/Development/sfmlbuild/lib/libsfml-audio.so'
collect2: error: ld returned 1 exit status
make[3]: *** [CMakeFiles/sfml_project.dir/build.make:88: sfml_project] Error 1

make[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/sfml_project.dir/rule] Error 2
make: *** [Makefile:118: sfml_project] Error 2
This is what I have in my CMakeLists.txt as well, which I assume locates most of the SFML files, so CLion can use them.
cmake_minimum_required(VERSION 3.7)
set(PROJECT_NAME sfml_project)
project(${PROJECT_NAME})
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++14 -static")
set(CMAKE_CXX_STANDARD 14)
set(SOURCE_FILES main.cpp)
if (CMAKE_BUILD_TYPE STREQUAL "Release")
add_executable(${PROJECT_NAME} WIN32 ${SOURCE_FILES})
else ()
add_executable(${PROJECT_NAME} ${SOURCE_FILES})
endif ()
set(SFML_ROOT "/home/user/Development/sfmlbuild")
cmake_policy(SET CMP0074 NEW)
set(SFML_STATIC_LIBRARIES FALSE)
set(CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/cmake_modules")
find_package(SFML REQUIRED COMPONENTS audio graphics window system)
if (SFML_FOUND)
include_directories(${SFML_INCLUDE_DIR})
target_link_libraries(${PROJECT_NAME} ${SFML_LIBRARIES} ${SFML_DEPENDENCIES})
endif ()
I'm unsure what to do from here, or if there's anything wrong in particular with how I have my CLion setup. I set my CMake application to the folder where I have my sfml_project. And my sfmlbuild which contains the Linux version of SFML, downloaded from the suit, is in a separate folder which is where the libsfml-audio.so is located inside of. As for the build, execution, and development part of the CLion program, I have the Toolchains to detect the Make, C compiler, and C++ compiler where I also left the profile that's available to default. Maybe those have to do with something that's wrong, but I'm honestly unsure what to do from here.
If anyone can provide me feedback, small or large, then I would greatly appreciate it and try to get back as fast as I can with responses on whether or not I've done certain things.
I furthermore apologize as this is my first time utilizing this website to ask for any questions, so if this is a question poorly done, I accept my inexperience, and I hope to do better next time.

I suppose I should've put what the errors were exactly as well, so I'll add them here too.

I apologize for posting all of this information so late; I still don't quite understand too much, but I hope this gives some more information for aid.
One potential issue is your find_package flag, looking on at a project I've made I used
find_package(SFML 2.5.1 COMPONENTS graphics audio REQUIRED)
Try putting the version number
another issue, according to this website SFML_ROOT is replaced by SFML_DIR. Hers the website: https://en.sfml-dev.org/forums/index.php?topic=24070.0
How can I add prerequisite rule for all source files (c/cpp)? It would be simple if entire make file was done by me, but I use android build system that hides most of the stuff from me.
The reason I want to do it:
I added a rule to generate my header file which is included by some c/cpp files. It works well as long as dependencies are already generated. However, with a clean project there is no dependency info available before compilation and as a result make won't run my rule for a clean project because it doesn't know that certain cpp file depends on a header file that doesn't exist yet. That's why I need to add some kind of rule to ensure that my prerequisite rule runs before any compilation takes place.
So far, I did this:
include $(CLEAR_VARS)
.PHONY: ForceRule
MyHeader.h: ForceRule
ForceRule: CreateHeader.sh
$(shell CreateHeader.sh MyHeader.h)
# below is standard android way to build shared lib from cpp files:
LOCAL_SRC_FILES: File1.cpp File2.cpp
LOCAL_PATH := $(CURDIR)
include $(BUILD_SHARED_LIBRARY)
It's hard to be sure with black-box makefiles (and I think your approach is wrong), but you could try this:
MyHeader.h: CreateHeader.sh
$(shell CreateHeader.sh MyHeader.h)
%.o: %.cpp MyHeader.h
I am using a mix of Java and native JNI C++ code for an android project, using NDK r8b, in Eclipse in OSX. I want to be able to use the regular C++ classes (map, string) in std namespace.
In the Android.mk file the following were added:
APP_STL := stlport_shared
Here I also tried static library. Refer to http://docs.huihoo.com/android/ndk/r5/CPLUSPLUS-SUPPORT.html
STLPORT_FORCE_REBUILD := true
Also tried removing the forced build.
In the C/C++ path and variables:
${NDKROOT}/sources/cxx-stl/stlport/stlport
"map" and "string" headers were included in the .cpp file. I am able to use std::string and std::map. The assistant picks up on them. When searching for the definition (F3 in eclipse) the header file is shown, i.e. resolved. Also, the outline shows the "string" and "map" header files and when double clicking them it also brings the headers to the forefront.
However, the build doesn't pick them up. I get the following:
> ndk-build
> Gdbserver : [arm-linux-androideabi-4.6] libs/armeabi/gdbserver
> Gdbsetup : libs/armeabi/gdb.setup
> Gdbserver : [arm-linux-androideabi-4.6] libs/armeabi-v7a/gdbserver
> Gdbsetup : libs/armeabi-v7a/gdb.setup
> Compile++ arm : ImageTargets <= ImageTargets.cpp
> xxx/Project/Code/MyImageTarget/jni/ImageTargets.cpp:20:18: fatal error: string: No such file > or directory
> compilation terminated.
> make: *** [xxx/Project/Code/MyImageTarget/obj/local/armeabi/objs-> debug/ImageTargets/ImageTargets.o] Error 1
Has anyone any idea what else is there to try.
Use V=1 parameter on ndk-build command line. This will echo all executed commands, including compilation and link, with all their parameters that NDK build assigns.
In your case, the answer can be found without detailed build log:
In the Android.mk file the following were added:
APP_STL := stlport_shared
This is your mistake. The document you cited explains that this setting should go into Application.mk. This file is usually considered optional. Yes it is. Instead of creating this file, you can specify APP_STL on the command line:
ndk-build V=1 APP_STL=stlport_static
I don't know why and how Eclipse resolves #include <string> or map.
I was trying to compile libSDL-1.2.14 for my mips platform.
But it was not successful.
These were the steps that I tried out :
export PATH=/opt/mips-4.3/bin:$PATH
Went inside the libSDL-1.2.14 source folder.
Gave a "./configure --prefix=/usr/local/SDL_Lib --host=mips-linux-gnu"
Executed the "make" command
This was the error received :
cc1: warning: include location
"/usr/include" is unsafe for
cross-compilation
./src/audio/dma/SDL_dmaaudio.c: In

./src/audio/dma/SDL_dmaaudio.c:167:
error: 'asm' operand has impossible

But then i reconfigured the make file by giving the following commands :
make clean
./configure --prefix=/usr/local/SDL_Lib --host=mips-linux-gnu CPPFLAGS=-I/opt/mips-4.3/mips-linux-gnu/libc/usr/include/
make
NOTE : /opt/mips-4.3/mips-linux-gnu/libc/usr/include/ - This is the path where you can locate the select.h file for the mips Platform.
It contains the definitions of the macros FD_ZERO and FD_SET.
Still I am getting the same error.

Please help me with some valuable pointers.

First, don't set the path to the cross-compiler as the first part of your PATH, set it as last:
export PATH=$PATH:<path to cross-compiler>
It's safer this way. Second, run ./configure --help to get all the options. What that error message would say if it was smarter is the following:
You're trying to cross-compile since you're setting the --host flag
But you're not changing any of the other options for where to find includes and libs for the target environment
I'm going to use /usr/include by default
But that's for the host system which will not work when cross-compiling
Check what other configure options you need to set to tell the configure script where to find the .h files (includes) and the libraries for your target. These usually come with the cross-compiler that you download. Also, you should probably set the CROSS_COMPILE environment variable to the cross-compiler prefix before running configure. The prefix is the part before gcc in a cross-compiler, assuming you're using GCC as your cross-compiler.
