adios does not compile/link on Apple Mac OS(Undefined symbols for architecture x86_64)

[burlen]

the full error is:

libtool: link: /usr/bin/clang -O2 -g -fPIC -o bpdump bpdump-bpdump.o  ../../src/libadios_internal_nompi.a
Undefined symbols for architecture x86_64:
  "_adiost_tool", referenced from:
      _adiost_pre_init in libadios_internal_nompi.a(libcoreonce_a-adiost_callback_internal.o)
     (maybe you meant: _my_adiost_tool, _default_adiost_tool )
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

don't know if it's related but I see numerous warning above about .a files with no symbols

/Library/Developer/CommandLineTools/usr/bin/ranlib: file: libadiosreadf.a(adiosf_defs_mod.o) has no symbols

@mw70 have you had success building adios on apple?

Kevin Huck has a fix for this...

[khuck]

I made a patch in my fork: https://github.com/khuck/ADIOS but I have to test it on other platforms before making the pull request.

@khuck Thank you! your patch fixed the mac build. You mentioned you hadn't tested on linux, so I gave it run. it breaks the linux build. error looks familiar.

[khuck]

OK, I removed the check for __clang__ for the weak definition, it should always be defined as a weak symbol now.

Is this fix merged yet? I am getting the same error on my mac.
