Hi!
I'm trying to build geogram in Ami Linux but I'm getting error. Below you will fin the error:

============== Geogram build configured ==================

To build geogram:

go to build/Linux64-gcc-dynamic-Release or build/Linux64-gcc-dynamic-Debug

run 'make' or 'cmake --build .'

Note: local configuration can be specified in CMakeOptions.txt
(see CMakeOptions.txt.sample for an example)
You'll need to re-run configure.sh if you create or modify CMakeOptions.txt

simogasp · 2018-06-26T10:24:49Z

Hi,
I think you need to install libpthread (it should be sudo apt-get install libpthread-stubs0-dev)
Also pay attention to this line

-- The C compiler identification is GNU 7.2.1
-- The CXX compiler identification is GNU 4.8.5

It seems like you have different versions installed for the c and c++ compiler. You may need to install g++7 to use the same version for c and c++

mario-pinderi · 2018-06-26T16:50:17Z

Hi,
I updated c++ and I can confirm that libpthread-stubs is installed. I'm using Ami Linux for this.
If you see this line:
Did not find GLFW3 in the system, using built-in GLFW3
It says that it can't find GLFW3, I can confirm that GLFW3 is installed without any error.

what does

locate libpthread.so

and

locate pthread.h

say?

Hi @mariopinderist @simogasp ,

Did anyone of you find the solution because I am also facing the same issue.

mkhairy · 2019-07-11T12:44:03Z

Hi @vishav26 @mariopinderist ,

Did you guys find a solution for this issue? Thanks!

tkircher · 2019-10-01T02:43:37Z

I'm having this issue too. Edit: Solved it by including this in the top-level CMakeLists.txt:

set(CMAKE_THREAD_LIBS_INIT "-lpthread")
set(CMAKE_HAVE_THREADS_LIBRARY 1)
set(CMAKE_USE_WIN32_THREADS_INIT 0)
set(CMAKE_USE_PTHREADS_INIT 1)
set(THREADS_PREFER_PTHREAD_FLAG ON)

Found this suggestion in another forum somewhere.

one-and-only · 2020-04-13T18:14:59Z

Indeed! works for me.

mr-sobol · 2020-04-14T14:02:56Z

Thank so much!

MiguelBtt · 2020-04-16T08:00:30Z

It works perfectly!!!

joyoFeng · 2020-04-17T08:18:59Z

I'm having this issue too. Edit: Solved it by including this in the top-level CMakeLists.txt:

set(CMAKE_THREAD_LIBS_INIT "-lpthread")
set(CMAKE_HAVE_THREADS_LIBRARY 1)
set(CMAKE_USE_WIN32_THREADS_INIT 0)
set(CMAKE_USE_PTHREADS_INIT 1)
set(THREADS_PREFER_PTHREAD_FLAG ON)

Found this suggestion in another forum somewhere.

that is cool, fix for me. Thank you

rubyFeedback · 2020-06-23T20:41:17Z

tkircher's code solved this for me. Hopefully the webkitgtk guys include that solution because I am having to use his workaround for the same problem (even recent webkitgtk does not find threads, unless I add the above code to the cmake file).

ghost · 2020-09-17T09:25:33Z

Thank you tkircher. It also solved the problem on my other llvm project

MiltosKoutsokeras · 2020-10-24T21:57:09Z

I'm having this issue too. Edit: Solved it by including this in the top-level CMakeLists.txt:

set(CMAKE_THREAD_LIBS_INIT "-lpthread")
set(CMAKE_HAVE_THREADS_LIBRARY 1)

set(CMAKE_USE_PTHREADS_INIT 1)
set(THREADS_PREFER_PTHREAD_FLAG ON)

Unfortunately this trick is not applicable to every environment. I do not build geogram, but I encountered the missing pthread functions during linking. It worked while building with CMake cross compilation an armhf target in Debian 10 and same sources fail in Arch Linux. So the trick is nice, but there are corner cases which fails. It seems that compilers or CMake have trouble with -pthreads flag. It seems that pthread shared objects are symlinked differently in every system, breaking builds. Unfortunatelly the only fix I managed to see working everywhere is linking straight to the SO file with absolute path. Something like this in CMake:

TARGET_LINK_LIBRARIES(my_target
#	${CMAKE_THREAD_LIBS_INIT} # FAILS
#	/opt/cross-toolchains/arm-linux-gnueabihf/lib/libpthread.so # FAILS
	/opt/cross-toolchains/arm-linux-gnueabihf/lib/libpthread-2.28.so # WORKS
#	/opt/cross-toolchains/arm-linux-gnueabihf/lib/libpthread.so.0 # FAILS
)

Where libpthread-2.28.so is the SO and libpthread.so is symlink to libpthread.so.0 which in turns is symlink to libpthread-2.28.so:

/opt/cross-toolchains/arm-linux-gnueabihf/lib/libpthread-2.28.so
/opt/cross-toolchains/arm-linux-gnueabihf/lib/libpthread.so -> libpthread.so.0
/opt/cross-toolchains/arm-linux-gnueabihf/lib/libpthread.so.0 -> libpthread-2.28.so

@tkircher, I'm installing the librealsense package from source using HomeBrew and got the below error.

CMake Error at /opt/homebrew/Cellar/cmake/3.20.5/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
Could NOT find Threads (missing: Threads_FOUND)
Call Stack (most recent call first):
/opt/homebrew/Cellar/cmake/3.20.5/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:594 (_FPHSA_FAILURE_MESSAGE)
/opt/homebrew/Cellar/cmake/3.20.5/share/cmake/Modules/FindThreads.cmake:238 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
examples/measure/CMakeLists.txt:9 (find_package)

I tried updating the config in the CMakeLists.txt like you mentioned above but see that there are multiple CMakeLists.txt files in the package hierarchy. Which file do I make the changes to?

Also, I installed using 'brew install --build-from-source librealsense' as I was getting the following error with 'brew install'

'Error: librealsense: no bottle available!'

Update: The issue is fixed
