Hello, I'm evaluating Boost.Test. I did the initial evaluation using the header-only variant and now I'd like to move to dynamic linking the Test library for a larger-scale deployment. However, all attempts so far failed due to Undefined symbols for architecture x86_64: "_main", referenced from: implicit entry/start for main executable ld: symbol(s) not found for architecture x86_64 I'd put it down to my lack of experience with Test, or Boost in general, however I noticed that my libs/test/example's don't seem to build either. I'm on OS X Yosemite. I compile Boost with ./bootstrap.sh --prefix=<my_dir> ./b2 cxxflags="-stdlib=libc++" linkflags="-stdlib=libc++" ./b2 install As this doesn't seem to compile the necessary .dylibs I added <define>BOOST_TEST_DYN_LINK=1 <link>shared to the "requirements" section of the first target in libs/test/build/Jamfile.v2 and rebuilt just Boost.Test. Although I don't actually know what I was doing, this did seem to build the Boost.Test dynamic libraries, which tests are however failing to link against. The result looks the same on 1_56_0 and 1_57_0. Could someone please help me find the problem? I'm dubious about my building procedure in particular, could someone give me a complete sequence of steps necessary to build Boost with Boost.Test ready to be linked dynamically? I check the documentation, which is good and detailed but deals with various aspects in isolation and doesn't give a newcomer a good idea of the overall process. Cheers!
