boost symbol not found on mac on a.out start

[Anton Kochepasov]

Hi there,

I wanted to join folly user group, cloned folly repo, read README.md (which is really good), compiled folly with using macports (macports is my primary dev option on mac) and created a small example.cpp program:

#include <folly/Conv.h>

using namespace folly;

int main()

{

    fbstring str;

    toAppend(2.5, &str);

    return 0;

}

It's compilable with g++ (MacPorts gcc49 4.9.3_0):

g++ -I/usr/local/include -L/usr/local/lib -L /opt/local/lib -lfolly -ldouble-conversion -lglog -lboost_program_options-mt -std=c++11 -m64 example.cpp

so far so good. However, when I start the ./a.out I have the following problem:

dyld: Symbol not found: __ZNK5boost15program_options22error_with_option_name23substitute_placeholdersERKSs

  Referenced from: /usr/local/lib/libfolly.57.dylib

  Expected in: flat namespace

 in /usr/local/lib/libfolly.57.dylib

Trace/BPT trap: 5

Changing LD_LIBRARY_PATH or DYLD_LIBRARY_PATH doesn't help. How this loading can be fixed?

Thank you,

Anton
