[SOLVED] Determining if the include file pthread.h exists failed

[matscisteph]

Hello!

I am a new to SOFA and am installing everything on Windows 10 according to the instructions outlined here: https://www.sofa-framework.org/community/doc/getting-started/build/windows/

Everything seems ok until I try to configure everything in CMake, where I get the following error from the CMakeError.txt file:

Determining if the include file pthread.h exists failed with the following output:

As far as I can tell pthread is in the correct folder: C:\Users\User\sofa\src\applications\plugins\SensableEmulation\pthread

Could someone please direct me to a solution for this?

Thank you,

Hey @matscisteph

I’m not on Windows unfortunately so I cannot test it, but could you try to replace the following lines in the file sofa\src\applications\plugins\SensableEmulation\CMakeLists.txt :

set(SOURCE_FILES
    OmniDriverEmu.cpp
    initSensableEmulation.cpp
)

with

set(SOURCE_FILES
    OmniDriverEmu.cpp
    initSensableEmulation.cpp
)

if(MSVC)
    list(APPEND SOURCE_FILES "pthread/pthread.h")
endif()

Thanks @jnbrunet

I put that into the CMakeLists.txt you specified and am still getting the same error. Is there something else I can try?

Here is what my CMakeLists.txt looks like:

include(${SOFA_CMAKE_DIR}/preProject.cmake)

set(HEADER_FILES

    #NewOmniDriverEmu.h 
    OmniDriverEmu.h
	pthread/pthread.h
	)

set(SOURCE_FILES

    OmniDriverEmu.cpp
    initSensableEmulation.cpp 
    
)

if(MSVC)
    list(APPEND SOURCE_FILES "pthread/pthread.h")
endif()

set(README_FILES

	PluginSensableEmulation.txt
	)

IF(WIN32)
	set(THREADS_USE_PTHREADS_WIN32 true)
ENDIF()
find_package(Threads REQUIRED)
include_directories(${THREADS_PTHREADS_INCLUDE_DIR})

add_library(${PROJECT_NAME} SHARED ${HEADER_FILES} ${SOURCE_FILES} ${README_FILES})

AddCompilerDefinitions("SOFA_BUILD_SENSABLEEMULATIONPLUGIN")
AddLinkerDependencies(SofaGuiQt SofaComponentGeneral SofaHaptics ${CMAKE_THREAD_LIBS_INIT})

include(${SOFA_CMAKE_DIR}/postProject.cmake)

Thanks,

Ok I double checked everything and then changed the path for Qt in my Environment Variables from C:\Qt to C:\Qt\5.15.2\msvc2019_64\bin and that error disappeared. That seems to have solved the issue for now. Thanks!
