Hi. I’m trying to build Ganesha 3.4 (latest stable), and CMake output shows the following: -- Looking for pthread.h -- Looking for pthread.h - found -- Performing Test CMAKE_HAVE_LIBC_PTHREAD -- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failed -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found -- Found Threads: TRUE However CMake fails with the following in CMakeError.log. Not sure how to proceed. Please advise. Thanks. -Jeff Performing C SOURCE FILE Test CMAKE_HAVE_LIBC_PTHREAD failed with the following output: Change Dir: /u/jcbecker/ganesha.build/CMakeFiles/CMakeTmp Run Build Command(s):/usr/bin/gmake cmTC_52ec6/fast && /usr/bin/gmake -f CMakeFiles/cmTC_52ec6.dir/build.make CMakeFiles/cmTC_52ec6.dir/build gmake[1]: Entering directory '/u/jcbecker/ganesha.build/CMakeFiles/CMakeTmp' Building C object CMakeFiles/cmTC_52ec6.dir/src.c.o /usr/bin/cc -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -fno-strict-aliasing -DCMAKE_HAVE_LIBC_PTHREAD -o CMakeFiles/cmTC_52ec6.dir/src.c.o -c /u/jcbecker/ganesha.build/CMakeFiles/CMakeTmp/src.c Linking C executable cmTC_52ec6 /usr/bin/cmake -E cmake_link_script CMakeFiles/cmTC_52ec6.dir/link.txt --verbose=1 /usr/bin/cc -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -fno-strict-aliasing -DCMAKE_HAVE_LIBC_PTHREAD -rdynamic CMakeFiles/cmTC_52ec6.dir/src.c.o -o cmTC_52ec6 /usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: CMakeFiles/cmTC_52ec6.dir/src.c.o: in function `main': src.c:(.text+0x2d): undefined reference to `pthread_create' /usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: src.c:(.text+0x39): undefined reference to `pthread_detach' /usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: src.c:(.text+0x45): undefined reference to `pthread_cancel' /usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: src.c:(.text+0x56): undefined reference to `pthread_join' /usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: src.c:(.text+0x6a): undefined reference to `pthread_atfork' collect2: error: ld returned 1 exit status gmake[1]: *** [CMakeFiles/cmTC_52ec6.dir/build.make:104: cmTC_52ec6] Error 1 gmake[1]: Leaving directory '/u/jcbecker/ganesha.build/CMakeFiles/CMakeTmp' gmake: *** [Makefile:138: cmTC_52ec6/fast] Error 2 Source file was: #include <pthread.h> void* test_func(void* data) { return data; } int main(void) { pthread_t thread; pthread_create(&thread, NULL, test_func, NULL); pthread_detach(thread); pthread_cancel(thread); pthread_join(thread, NULL); pthread_atfork(NULL, NULL, NULL); pthread_exit(NULL); return 0; } Determining if the function pthread_create exists in the pthreads failed with the following output: Change Dir: /u/jcbecker/ganesha.build/CMakeFiles/CMakeTmp Run Build Command(s):/usr/bin/gmake cmTC_3a45d/fast && /usr/bin/gmake -f CMakeFiles/cmTC_3a45d.dir/build.make CMakeFiles/cmTC_3a45d.dir/build gmake[1]: Entering directory '/u/jcbecker/ganesha.build/CMakeFiles/CMakeTmp' Building C object CMakeFiles/cmTC_3a45d.dir/CheckFunctionExists.c.o /usr/bin/cc -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -fno-strict-aliasing -DCHECK_FUNCTION_EXISTS=pthread_create -o CMakeFiles/cmTC_3a45d.dir/CheckFunctionExists.c.o -c /usr/share/cmake/Modules/CheckFunctionExists.c Linking C executable cmTC_3a45d /usr/bin/cmake -E cmake_link_script CMakeFiles/cmTC_3a45d.dir/link.txt --verbose=1 /usr/bin/cc -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -fno-strict-aliasing -DCHECK_FUNCTION_EXISTS=pthread_create -rdynamic CMakeFiles/cmTC_3a45d.dir/CheckFunctionExists.c.o -o cmTC_3a45d -lpthreads /usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: cannot find -lpthreads collect2: error: ld returned 1 exit status gmake[1]: *** [CMakeFiles/cmTC_3a45d.dir/build.make:104: cmTC_3a45d] Error 1 gmake[1]: Leaving directory '/u/jcbecker/ganesha.build/CMakeFiles/CMakeTmp' gmake: *** [Makefile:138: cmTC_3a45d/fast] Error 2
