[Boost-users] [Test] failure linking tests dynamically

Subject: [Boost-users] [Test] failure linking tests dynamically

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!
