Firebreath won't compile using Xcode 5.0.2

Question

I'm trying to build the OSX Firebreath plugin. It builds just fine if I set the target OS to 10.8, but if I try to move it back to 10.6, I get the following error message:

/Users/dwiedeback/Github/plugin-dev/
   firebreath/src/libs/log4cplus/include/
   log4cplus/internal/internal.h:142:8: 

   error: thread-local storage is unsupported for the current target

Not sure why thread-local storage isn't supported for 10.6. Has anyone run into this with Firebreath?

Answer 1

You can probably avoid this issue if you manage not to have LOG4CPLUS_HAVE_TLS_SUPPORT defined in log4cplus' defines.hxx . Then the log4cplus source will not try to use the __thread keyword and will use POSIX thread-local storage facilities instead.

However, the best of all options would be to debug and find out why is the TLS check in ConfigureChecks.cmake giving a false positive.
