Description gallo33 2011-08-15 21:31:57 UTC

Description of problem:
Linking the interprocess boost library against rt library causes the following error:
/usr/bin/ld: note: 'pthread_mutexattr_settype@@GLIBC_2.2.5' is defined in DSO /lib64/libpthread.so.0 so try adding it to the linker command line
/lib64/libpthread.so.0: could not read symbols: Invalid operation

Version-Release number of selected component (if applicable):
1.46.0

How reproducible:
Just build the first example in the page http://www.boost.org/doc/libs/1_47_0/doc/html/interprocess/quick_guide.html
I tried to link the project with the line:
/usr/lib64/ccache/c++   -g   CMakeFiles/Boost-ICP.dir/src/main.cpp.o  -o Boost-ICP -rdynamic -lrt

Comment 1 Petr Machata 2011-08-16 12:48:36 UTC

You need to compile with -pthread.  Boost.Interprocess is a source-level library, so there's no way for the library itself to "smuggle" the pthread libraries to the command line.
