I have been working through the LLVM Kaleidoscope Tutorial for OCaml. On the third part of the tutorial, I have navigated to the example code in the folder
OCaml-Kaleidoscope\Chapter3
I am encountering an issue when compiling with
ocamlbuild toy.byte
on cygwin. This is the code given in the tutorial to compile.
The error I am getting is
''ocamlc.opt -c -o codegen.cmo codegen.ml
File "codegen.ml", line 5, characters 5-9:
Error: Unbound module Llvm
Exit code 2 while executing this command:
''ocamlc.opt -c -o codegen.cmo codegen.ml
I looked up some solutions to this issue. One solution I found was to use
ocamlbuild -use-ocamlfind toy.byte -package llvm
instead of
ocamlbuild toy.byte
However, when I tried that I received this error:
Failure: ocamlfind not found on path, but -no-ocamlfind not used.
To fix this I tried:
opam install ocamlfind
But ocamlfind is already installed.
Another solution I found was to use:
opam install llvm
This resulted in:

`opam depext llvm.3.7' may help you find the correct installation for your

I am using version 3.8.0 of llvm and version 4.02.3 of OCaml from this link.
Am I on the right track? What do I need to do to fix this?
As I have answered in your question LLVM tutorial OCaml Compilation Assembler Error, your best way is not to use Windows.
OPAM is now usable in Cygwin OCaml or even in MinGW OCaml (using Cygwin opam binary) but packages in the OPAM repository are not tested in these environments. Just avoid them unless you are experienced with OCaml program development in Windows.
If you stick to Windows, then check the build at C:\cygwin64\home\setup\.opam\system\build\llvm.3.7. There should be stdout and stderr log files which can help to understand what happend.

Initially, I had pcl-1.10 in /usr/(installed using sudo apt install libpcl-dev). Then I self-built pcl-1.12 in /usr/local/ for some reason. Now I uninstalled pcl-1.12 using sudo make uninstall and wanted to use the default pcl-1.10. But when I compiled my project, the error message showed
$ colcon build --cmake-args -DCMAKE_BUILD_TYPE=Release
Starting >>> lidarslam_msgs
Starting >>> ndt_omp_ros2
--- stderr: ndt_omp_ros2
make[2]: *** No rule to make target '/usr/local/lib/libpcl_surface.so', needed by 'align'. Stop.

make: *** [Makefile:141: all] Error 2
---
Failed <<< ndt_omp_ros2 [0.16s, exited with code 2]
It seems that the PATH stills points to the /usr/local/lib even if I uninstalled the package. Is there a way I can reset PATH to the global package path? For this case, I believe the pcl-1.10's libpcl_surface.so is in /usr/lib/x86_64-linux-gnu/libpcl_outofcore.so .
I am working on ROS2 and compiling the CMakeList.txt using colcon. So I can't modify the makefile. I assume it is a PATH problem.
A way is to use symlink to link all the .so file in /usr/lib/x86_64-linux-gnu/ to /usr/local/lib but I found it kind of stupid...
I have some makefile that is used to compile a program. During compilation I get an error:
In file included from kernel/driver.cc:20:
./kernel/yosys.h:81:12: fatal error: tcl.h: No such file or directory
81 | # include <tcl.h>
| ^~~~~~~
compilation terminated.
make: *** [Makefile:696: kernel/driver.o] Error 1
Then I rerun Cygwin setup application and install new package tcl-devel. I restart the Cygwin terminal and try again. The same error pops up. I don't understand! Why aren't headers found?
My tcl and tcl-devel are both of version 8.6.11-1.
I'm trying to build PCL 1.8.0 on my Ubuntu 14.04 machine from source, following these instructions. But every time I get the following error:

for locate QWidget I get amongst others the following output:
...
/usr/include/qt4/QtGui/QWidget
...
/usr/include/qt5/QtWidgets/QWidget
...
So how can I resolve the error and install pcl?
The problem happens because your configuration is trying to mix Qt4 and Qt5 during PCL build.
According to the link you've provided, PCL is suppossed so be built against Qt4 in this case.
Try to remove everything in release directory and re-initialize CMake config with correct version of Qt.
Like that (following provided example):
cd ~/Documents/pcl
rm -rf relese
mkdir release
cd release
cmake -DCMAKE_BUILD_TYPE=Release -DPCL_QT_VERSION=4 -DBUILD_GPU=ON -DBUILD_apps=ON -DBUILD_examples=ON ..
make
I am trying to compile QT 5.5.1 on Amazon AMI 2015.09, which looks la lot like Centos 6.5.
I keep getting this error:
Project ERROR: Unknown module(s) in QT: quick
However, there is no quick module that I can find, and no obvious way to enable to disable it from looking at the ./configure script.
My procedure:
I downloaded qt-everywhere-opensource-src-5.5.1.tar.gz
I unpacked it.
I ran ./configure
Confirmed that I want the opensource license and agreed to the LGPL.
Ran gmake -j4 (but I get the same behavior with gmake.
Interestingly, make distclean gives me this error:
Project ERROR: Unknown module(s) in QT: quick-private

At another poster's suggestion I tried ./configure -skip qtquick but that didn't work:
$ ./configure -skip qtquick
+ cd qtbase
+ /home/ec2-user/qt-everywhere-opensource-src-5.5.1/qtbase/configure -top-level -skip qtquick
Attempting to skip non-existent module qtquick.

this is what I think will solve your problems:
You have use `make confclean' instead of making distclean for deleting the previous configuration.
Configure in verbose mode — more information will be provided, sorry, I don't remember exact flag, if I'm not mistaken, it's -v.
If you don't need quick, add -skip qtquick to the configure.
I want to install octaviz package in octave software.
From the documentation there is stated:
-You'll need octave 2.1.53 or later and VTK CVS to build octaviz. To compile octaviz, run ccmake . in the root directory of the source tree, then make and finally make install.
I first ran ccmake ., and it completed successfully after I installed some libs that I was missing.
But, the I ran "make" and it exits with the following errors:
>> make
[ 1%] Built target vtkWrapOctave
[ 1%] Building CXX object Common/CMakeFiles/octaviz.dir/octaviz.o
/home/user12345/octave/octaviz/Common/octaviz.cc:31:24: fatal error: octave/oct.h: No such file or directory
#include <octave/oct.h>
^
compilation terminated.
make[2]: *** [Common/CMakeFiles/octaviz.dir/octaviz.o] Error 1
make[1]: *** [Common/CMakeFiles/octaviz.dir/all] Error 2
make: *** [all] Error 2
Any idea what I am missing here?
You are missing the octave/oct.h header. This usually means that you don't have Octave installed. If you do have it installed, maybe you are missing the header files and shared libraries (if you are using Linux, did you install octave's -dev or -devel packaqes?) If you have them installed, you must have ran the configure script incorrectly. Either specify the correct options or set the CXX_FLAGS. If you don't know about compiler flags you probably should not change them and instead figure out how to install the octave libraries correctly.
