Hi all, I have the following issue trying a fresh installation on a VM-Ubuntu 18.04. After installing the dependencies etc from here: https://wiki.gnuradio.org/index.php/UbuntuInstall
and after checking out the maint_3.7 branch the cmake fails with the following CMakeError.log file. Something tell me I am missing something obvious, but don't know what... This is the first time I see something like this. Any help is appreciated. best Achilleas ----------- Determining if the pthread_create exist failed with the following output: Change Dir: /home/anastas/workarea-gnuradio/build_maint37/CMakeFiles/CMakeTmp Run Build Command:"/usr/bin/make" "cmTC_a2fc5/fast" /usr/bin/make -f CMakeFiles/cmTC_a2fc5.dir/build.make CMakeFiles/cmTC_a2fc5.dir/build make[1]: Entering directory '/home/anastas/workarea-gnuradio/build_maint37/CMakeFiles/CMakeTmp' Building C object CMakeFiles/cmTC_a2fc5.dir/CheckSymbolExists.c.o /usr/bin/cc -std=gnu99 -fvisibility=hidden -Wsign-compare -Wall -Wno-uninitialized -o CMakeFi les/cmTC_a2fc5.dir/CheckSymbolExists.c.o -c /home/anastas/workarea-gnuradio/build_maint37/CMakeF iles/CMakeTmp/CheckSymbolExists.c Linking C executable cmTC_a2fc5 /usr/bin/cmake -E cmake_link_script CMakeFiles/cmTC_a2fc5.dir/link.txt --verbose=1 /usr/bin/cc -std=gnu99 -fvisibility=hidden -Wsign-compare -Wall -Wno-uninitialized -rdynamic CMakeFiles/cmTC_a2fc5.dir/CheckSymbolExists.c.o -o cmTC_a2fc5 CMakeFiles/cmTC_a2fc5.dir/CheckSymbolExists.c.o: In function `main': CheckSymbolExists.c:(.text+0x1b): undefined reference to `pthread_create' collect2: error: ld returned 1 exit status CMakeFiles/cmTC_a2fc5.dir/build.make:97: recipe for target 'cmTC_a2fc5' failed make[1]: *** [cmTC_a2fc5] Error 1 make[1]: Leaving directory '/home/anastas/workarea-gnuradio/build_maint37/CMakeFiles/CMakeTmp' Makefile:126: recipe for target 'cmTC_a2fc5/fast' failed make: *** [cmTC_a2fc5/fast] Error 2 File /home/anastas/workarea-gnuradio/build_maint37/CMakeFiles/CMakeTmp/CheckSymbolExists.c: /* */ #include <pthread.h> int main(int argc, char** argv) { (void)argv; #ifndef pthread_create return ((int*)(&pthread_create))[argc]; #else (void)argc; return 0; #endif } Determining if the function pthread_create exists in the pthreads failed with the following output : Change Dir: /home/anastas/workarea-gnuradio/build_maint37/CMakeFiles/CMakeTmp Run Build Command:"/usr/bin/make" "cmTC_cfcc3/fast" /usr/bin/make -f CMakeFiles/cmTC_cfcc3.dir/build.make CMakeFiles/cmTC_cfcc3.dir/build make[1]: Entering directory '/home/anastas/workarea-gnuradio/build_maint37/CMakeFiles/CMakeTmp' Building C object CMakeFiles/cmTC_cfcc3.dir/CheckFunctionExists.c.o /usr/bin/cc -std=gnu99 -fvisibility=hidden -Wsign-compare -Wall -Wno-uninitialized -DCHECK_FUNCT ION_EXISTS=pthread_create -o CMakeFiles/cmTC_cfcc3.dir/CheckFunctionExists.c.o -c /usr/share/c make-3.10/Modules/CheckFunctionExists.c Linking C executable cmTC_cfcc3 /usr/bin/cmake -E cmake_link_script CMakeFiles/cmTC_cfcc3.dir/link.txt --verbose=1 /usr/bin/cc -std=gnu99 -fvisibility=hidden -Wsign-compare -Wall -Wno-uninitialized -DCHECK_FUNCTI ON_EXISTS=pthread_create -rdynamic CMakeFiles/cmTC_cfcc3.dir/CheckFunctionExists.c.o -o cmTC_c fcc3 -lpthreads /usr/bin/ld: cannot find -lpthreads collect2: error: ld returned 1 exit status CMakeFiles/cmTC_cfcc3.dir/build.make:97: recipe for target 'cmTC_cfcc3' failed make[1]: *** [cmTC_cfcc3] Error 1 make[1]: Leaving directory '/home/anastas/workarea-gnuradio/build_maint37/CMakeFiles/CMakeTmp' Makefile:126: recipe for target 'cmTC_cfcc3/fast' failed make: *** [cmTC_cfcc3/fast] Error 2 ---------
