[OMPI devel] Open MPI: Undefined reference to pthread_atfork

Fri, 22 Jun 2018 12:29:18 -0700

Hi,

 

When compiling a C++ source file named test.cpp that needs a shared library named libUtils.so (which in its turn needs Open MPI shared library, hence the parameter -Wl,-rpath-link,/home/dummy/openmpi/build/lib ) as follows:

g++ test.cpp -lUtils -Wl,-rpath-link,/home/dummy/openmpi/build/lib


An error is thrown /home/dummy/openmpi/build/lib/libopen-pal.so.20: undefined reference to pthread_atfork.



I passed -pthread and -lpthread (before and after -lUtils) to g++ but none of these solved the error.



 



Environment where this error is thrown:



OS: Ubuntu 14.04



Compiler: g++ 4.9



MPI: Open MPI 2.1.3



 



Thank you for your help,



L.
