I'm integrating C check framework for my project and I was able to run
autoreconf --install
successfully without any errors.
But when I integrate the C check framework, I'm getting an error and warnings that doesn't make sense.
Here is the error I'm getting
src/Makefile.am:7: warning: variable 'main_LDADD' is defined but no program or
src/Makefile.am:7: library has 'main' as canonical name (possible typo)
tests/Makefile.am:2: error: 'SHELLTESTS_PROGRAMS' is used but 'SHELLTESTSdir' is undefined
tests/Makefile.am:3: warning:variable 'ShellTests_SOURCES' is defined but no program or
tests/Makefile.am:3: library has 'ShellTests' as canonical name (possible typo)
tests/Makefile.am:5: warning: variable ShellTests_LDADD' is defined but no program or
tests/Makefile.am:5:library has 'ShellTests' as canonical name (possible typo)
autoreconf:automake failed with exit status: 1
I've followed the C check example source code, the difference between that and my project is that my class uses other class' methods.
Anyways, this is the Makefile.am under my tests/ that is causing 'havoc' on building the project
TESTS = shelltests
SHELLTESTS_PROGRAMS = shelltests
ShellTests_SOURCES = ShellTests.c $(top_builddir)/src/Shell.h $(top_builddir)/src/Parser.h $(top_builddir)/src/JobControl.h
ShellTests_CFLAGS = #CHECK_CFLAGS#
ShellTests_LDADD = $(top_builddir)/src/libshell.la #CHECK_LIBS#
This is the file structure for my project
src -
Parser.h, Parser.c, Shell.h, Shell.c, Job.h, Job.c, Makefile.am
tests -
ShellTests.c Makefile.am
And this is the code in Makefile.am under src.
lib_LTLIBRARIES = libshell.la
libshell_la_SOURCES = Shell.c Shell.h Parser.h Parser.c JobControl.h JobControl.c
bin_programs = main
main_sources = Main.c
main_LDADD = libshell.la
I followed this user's advice to see if it removes the error: What directory should I use for "error: 'extra_PROGRAMS' is used but 'extradir' is undefined"?
Alas, it does not.
I've tried building the example project - the one that you get when you download under examples, to see if I'm missing anything. But it's not able to build on my machine.
I'm on Mac OS X Mavericks (10.9)
Autoconf 2.69
Automake 1.15
Libtool 2.4.6
Check 0.9.14
I did a couple of things to build this project successfully. I first followed what I outlined here: Check framework example giving me error when running './configure'
Then I followed c check frameworks' naming conventions for the tests source files.
Thanks for the help guys, it gave me some ideas on what the cause of compilation errors.

I inherited a C++ code with a dependency to OpenMPI that I want to delegate to Conan and CMake, and the automated build has a strange (to me at least) behavior related to sysctl that I want to understand.
How I tried to do it
I declared the required dependencies in my root CMakeLists.txt:
Note: I added the full list of requirements because I also suspect that some of them may be in conflict? That happened before with boost, that forced me to set explicitly zlib (if i remember correctly).
# stuff ...
conan_cmake_configure(
REQUIRES
zlib/1.2.12
mp-units/0.7.0
boost/1.79.0
openmpi/4.1.0
gsl/2.7
cspice/0067
GENERATORS
cmake
# that is required for cspice
CMakeDeps
CMakeToolchain
)
# more stuff ...
and then in the application CmakeLists.txt I find, include and link the executable to the required libraries:
add_executable(spock main.cpp)
find_package(cspice REQUIRED)
find_package(openmpi REQUIRED)
target_include_directories(
spock PRIVATE $<BUILD_INTERFACE:${PROJECT_SOURCE_DIR}/include>
$<BUILD_INTERFACE:${CMAKE_CURRENT_LIST_DIR}/include>
openmpi_INCLUDE_DIRS
cspice_INCLUDE_DIRS
)
target_link_libraries(spock
CONAN_PKG::boost
CONAN_PKG::mp-units
openmpi::openmpi
cspice::cspice
)
# We need C++ 20 activated with the concepts library
target_compile_features(spock PUBLIC cxx_std_20)
Problem: undefined reference to sysctl ... on my local system only.
Building on my local machine with CMake 3.23.2 results in the following error message:
Consolidate compiler generated dependencies of target spock
[ 25%] Building CXX object src/CMakeFiles/spock.dir/main.cpp.o

gmake: *** [Makefile:146: all] Error 2
However, the same build on Github workflows on Ubuntu 20.04 works. What is weird. The only difference before apart the distribution version is that github wokflows use higher privileges than me on local (I believe?).
What I tried so far
I've been trying to read about what this sysctlreference is. And I found conflicting information:
Frrom this man page:
The sysctl() function retrieves system information and allows processes with appropriate privileges to set system information.
this similar SO question came to the conclusion that
Linux does not support this function (other OS like MacOS or FreeBSD support it)
A comment from the same post concludes that in Linux,
these details can be obtained by reading the kernel-provided
pseudofiles /proc/cpuinfo and /proc/meminfo
So here is my question: why does it compile at all on the remote server if this command is not supposed to exist on the OS used?
I am attempting to set up a new Stack project on NixOS with GHCJS as the compiler following the instructions at http://docs.haskellstack.org/en/stable/ghcjs.html
I have included in my stack.yaml file the following lines of code (all on one line because tab spaces seem to give issues):
# Compiler specifying the GHCJS compiler for this project (using improved base).
compiler: ghcjs-0.2.0.20151230.3_ghc-7.10.2
compiler-check: match-exact
setup-info:
ghcjs: source:
ghcjs-0.2.0.20151230.3_ghc7.10.2:
url: "https://github.com/nrolland/ghcjs/releases/download/v.0.2.0.20151230.3/ghcjs-0.2.0.20151230.3.tar.gz"
and I have retrieved the following error message when I ran stack setup
Could not parse '/home/lorkaan/pandocJS/stack.yaml':
InvalidYaml (Just (YamlParseException {yamlProblem = "mapping values are not allowed in this context", yamlContext = "", yamlProblemMark = YamlMark {yamlIndex = 487, yamlLine = 12, yamlColumn = 17}}))
See https://github.com/commercialhaskell/stack/blob/release/doc/yaml_configuration.md.
Additionally, I tried removing the setup-info field because Stack was complaining about it, leaving my stack.yaml file like:
# Compiler specifying the GHCJS compiler for this project (using improved base).
compiler: ghcjs-0.2.0.20151230.3_ghc-7.10.2
compiler-check: match-exact
which produces this output with the stack setup command:
Warning: /home/lorkaan/pandocJS/stack.yaml: Unrecognized field in ProjectAndConfigMonoid: compiler
Preparing to install GHC to an isolated location.
This will not interfere with any system-level installation.
Already downloaded.
The following executables are missing and must be installed: make
Does anybody have any idea why this would be happening?
the first error is because of a basic syntax error in your YAML configuration. The correct version would be:
setup-info:
ghcjs:
source:
ghcjs-0.2.0.20151230.3_ghc7.10.2:
url: "https://github.com/nrolland/ghcjs/releases/download/v.0.2.0.20151230.3/ghcjs-0.2.0.20151230.3.tar.gz"
The second error is because of exactly what it says: you are lacking the make utility. You need to use your Linux distribution's package management system to install make. Since I don't know which distribution you are on, I can only recommend simply executing the $ make command and seeing if the environment is smart enough to point out which package it can be found in. Ubuntu typically does that. Then it's only a matter of apt-get install-ing the package, or possibly yum install-ing on e.g. CentOS and Fedora, etc.
P.S. questions like yours normally get a downvote for not having shown sufficient effort in diagnosing the problem (or for putting 2 totally separate problems under a single question) but I'm giving you the benefit of the doubt and just hoping you'll be tidier next time.
I'm having trouble trying to do something seemingly very simple with CMake 2.8.11.2 . I have a folder with two files:
-- CMAkeLists.txt --
add_executable(test test.c)
target_link_libraries (test somelib)
-- test.c --
// Some c code
when I create a build directory and issue cmake .., cmake runs with the following output:
C:\Users\Enis\workspace_kepler\tmp\build>cmake ..
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
-- Configuring done
-- Generating done
-- Build files have been written to: C:/Users/Enis/workspace_kepler/tmp/build
And an MSVC 2012 solution is generated inside the build folder (as I have MSVC2012 installed). Now, the problem is that when I open that solution and check the linker configuration of the test project under Properties->Configuration Properties->Linker->Input->Additional Dependencies I see that somelib is added as ;-lsomelib.lib and visual studio doesn't like that. It links successfuly only if I change that to somelib.lib manually.
What am I doing wrong? Why does CMake make such a simple mistake? What can I do to change the prefix it generates?
I faced the same issue. The root of the problem is CMAKE_LINK_LIBRARY_FLAG but I have no idea what sets it. Resetting it, demonstrated in the snippet below, should help you.
set(CMAKE_LINK_LIBRARY_FLAG "")
There appears to be a Ant / jni.h problem (for my setup) with LibusbJava. I get the following error when setting up LibusbJava by running
ant linux
in CentOS 6.3 as root (quick and dirty test, thanks for those concerned about user level =0). I will redo with proper restrictions as shown on a libusbjava reference after reflection when first install works. LibusbJava, is a Java wrapper for the libusb library.
The output starts out like this:
[root#somebox LibusbJava]# ant linux -lib $JAVA_HOME/include -lib $JAVA_HOME/include/linux
Buildfile: build.xml
clean:
Build LibusbJava Test Linux:
Build LibusbJava Test:
[echo] Building Library for unit tests:
[exec] /.../libusbjava/trunk/LibusbJava/LibusbJava.cpp:27:17: error: jni.h: No such file or directory
[exec] /.../libusbjava/trunk/LibusbJava/LibusbJava.cpp:34:26: error: test/CuTest.h: No such file or directory
`...`
as it was not set on my system. It appears that jni.h is a header called by C++ code, which I had to add to the LibusbJava.cpp file. This is the new include, /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9.x86_64/include/jni.h. I then get an error with jni.h not being able to fine jni_md.h which is an include in jni.h #include "jni_md.h".
Clearly this is not the right approach, so perhaps I need a correct Ant reference, but I cannot seem to do it with a -lib switch. Besides, this just creates thousands of jni.h file errors during the Ant build attempt.
How can I fix this problem?
Notes: I've set$JAVA_HOME up like JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9.x86_64 and javac and java work fine.
New discovery... after helpful questions which guided me, I am much closer to successful compilation.
When I install LibusbJava and manually install all the library references in build.xml there is still an error compiling the LibusbJava based on a memset error. I see memset patches for libusb that appeared in 2007 and it's unclear how to use or if they relate. Investigating... Hints, comments and questions welcome. My most sincere thanks for the help thus far.

BUILD FAILED
but I find no referece to an include string.h or cstring. The header of Usb_Device.cpp mentions it is a C++ Stub for the java class of a java class ch.ntb.inf.libusbJava.Usb_Device. which only has this include #include "Usb_Device.h" which also does not appear to have a string include. Perhaps just insertion of#include`?
I have a CMake module to locate FreeGLUT:
FIND_PATH(FREEGLUT_INCLUDE_DIR NAMES GL/freeglut.h)
FIND_LIBRARY(FREEGLUT_LIBRARY NAMES freeglut freeglut_static)
SET(FREEGLUT_LIBRARIES ${FREEGLUT_LIBRARY})
SET(FREEGLUT_INCLUDE_DIRS ${FREEGLUT_INCLUDE_DIR})
INCLUDE(FindPackageHandleStandardArgs)
FIND_PACKAGE_HANDLE_STANDARD_ARGS(FreeGLUT DEFAULT_MSG FREEGLUT_LIBRARY FREEGLUT_INCLUDE_DIR)
MARK_AS_ADVANCED(FREEGLUT_INCLUDE_DIR FREEGLUT_LIBRARY)
It works fine and locates freeglut_static.lib when I generate NMake Makefiles on Windows. I'm attempting to statically link FreeGLUT into my DLL:
FIND_PACKAGE(FreeGLUT REQUIRED)
ADD_LIBRARY(vti SHARED ${VTI_SOURCES})
ADD_DEFINITIONS("-DBUILD_VTI=1 -DFREEGLUT_STATIC=1")
INCLUDE_DIRECTORIES(${CMAKE_SOURCE_DIR}/include ${FREEGLUT_INCLUDE_DIRS})
TARGET_LINK_LIBRARIES(vti ${FREEGLUT_LIBRARIES})
My source code builds correctly, but when it gets to the linking stage, VC++ fails with:
LINK : fatal error LNK1104: cannot open file 'freeglut.lib'
Which is strange since freeglut.lib isn't mentioned anywhere that I can see in the generated NMake makefiles. It should be trying to link with freeglut_static.lib, which CMake locates and sets in FREEGLUT_LIBRARIES.
What might be causing this?
This is caused with pragma directives in FreeGLUT code (see freeglut_std.h). Using FREEGLUT_STATIC should really fix that for you, but I think you should pass it to CMake without quotes: ADD_DEFINITIONS(-DBUILD_VTI -DFREEGLUT_STATIC)
