Description
If multiple types of the same boost library are installed (e.g. -d + -mt) it happens that RSB links under Snow Leopard against both boot libraries, resulting in undefined behavior at program startup.
If only a single boost variant is installed, everything works flawlessly except the linker still warning that it links against duplicate library entries.

This is probay an upstream bug in cmake as they provide the macro. the only thing i could imagine is that you compiled rsc with a different build type than rsb. under windows this causes troubles because cmake tries to find the boost version that matches the cmake build type and hence rsc would belinked against a different boost type than rsb itself.

I just started reinstalling both library types (mt + d) to check if I can reproduce the problem. What I already get (probably independent of the other problem) at the level of RSC are warnings about duplicate library entries:
Linking CXX executable ../build/TypeStringTools ld: warning: duplicate dylib /opt/local/lib/libboost_thread-mt-d.dylib ld: warning: duplicate dylib /opt/local/lib/libboost_filesystem-mt-d.dylib ld: warning: duplicate dylib /opt/local/lib/libboost_signals-mt-d.dylib ld: warning: duplicate dylib /opt/local/lib/libboost_program_options-mt-d.dylib ld: warning: duplicate dylib /opt/local/lib/libboost_system-mt-d.dylib [ 70%] Built target TypeStringTools

Can you post the linker command line (make VERBOSE=1)? and can yoz hav a look at what BOOST_LIBRARIES e.g. in the cmake cache? If there are no duplicate this is most likely an upstream bug.

Linker command:

In build/CMakeCache.txt, I couldn't find the BOOST_LIBRARIES variable. However, there is a variable rsc_dependencies which looks as follows:
//Dependencies for the target rsc_LIB_DEPENDS:STATIC=optimized;/opt/local/lib/libboost_thread-mt.dylib;debug;/opt/local/lib/libboost_thread-mt-d.dylib;optimized;/opt/local/lib/libboost_filesystem-mt.dylib;debug;/opt/local/lib/libboost_filesystem-mt-d.dylib;optimized;/opt/local/lib/libboost_signals-mt.dylib;debug;/opt/local/lib/libboost_signals-mt-d.dylib;optimized;/opt/local/lib/libboost_program_options-mt.dylib;debug;/opt/local/lib/libboost_program_options-mt-d.dylib;optimized;/opt/local/lib/libboost_system-mt.dylib;debug;/opt/local/lib/libboost_system-mt-d.dylib;

Ok, the same double linking also happens on linux, but GCC here is not that picky about it.
#6 Updated by J. Wienke over 12 years ago
Eh, but the linker command line you showed is from RSC... So there must be the same issue?

Applied in changeset r2829.
#8 Updated by S. Wrede over 12 years ago
Yes, the same issue applied to RSC. Compiling RSB, I still got for instance the following warning:
[ 81%] Building CXX object test/CMakeFiles/rsbtest.dir/rsb/InformerTask.cpp.o [ 81%] Building CXX object test/CMakeFiles/rsbtest_core.dir/rsb/EventIdTest.cpp.o Linking CXX executable ../build/rsbtest ld: warning: duplicate dylib /opt/local/lib/libboost_regex-mt-d.dylib ld: warning: duplicate dylib /opt/local/lib/libboost_date_time-mt-d.dylib
