I have issues linking yaml-cpp code. The weird thing is that it is compiler dependent. I am using homebrew to get yaml-cpp and gcc-4.8 . I have a simple program

#include <yaml-cpp/yaml.h>

int main(){
  YAML::Node yparams_;
  yparams = YAML::LoadFile("test.yaml");

  printf("all good\n");
  return 0;
}

It compiles and runs fine, if I use the 'g++' provided with mac

g++ test.cpp $(pkg-config --cflags --libs yaml-cpp) -o test

However, exchanging 'g++' to the homebrewed 'g++-4.8' gives me a long list of linker errors (attached below). If I run 'brew doctor' I do not get any warning. 'brew info yaml-cpp' returns with:

yaml-cpp: stable 0.5.1
http://code.google.com/p/yaml-cpp/
/usr/local/Cellar/yaml-cpp/0.5.1 (40 files, 1.0M) *
  Built from source with: --c++11
From: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/yaml-cpp.rb
==> Dependencies
Build: cmake ✔
Required: boost ✔

The output of 'brew info gcc' is

gcc: stable 4.8.3 (bottled), HEAD
http://gcc.gnu.org
/usr/local/Cellar/gcc/4.8.3_1 (1046 files, 184M) *
  Poured from bottle
From: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/gcc.rb
==> Dependencies
Required: gmp ✔, libmpc ✔, mpfr ✔, cloog ✔, isl ✔

I appreciate any hint on how to fix this issue. Thanks!

    You generally cannot link together things built with different C++ compilers, or different versions of the same compiler. You will get linker errors at best, mysterious crashes at run time or incorrect results at worst. – n. m. could be an AI Jul 22 '14 at 16:02

    More precisely, it looks like your preinstalled gcc uses libc++, and is therefore probably a clang++ in disguise, while your brewed g++ is a bona fide g++ using libstdc++. Check it witg g++ -v or whatever. If this is the case, you cannot use the two compilers together to compile interdependent pieces of C++ code in the same prigram. – n. m. could be an AI Jul 22 '14 at 16:38
  • You are right, the preinstalled gcc is a clang compiler. I guess homebrew uses the preinstalled compiler to install yaml-cpp. This is probably the reason, why I cannot link against it, when I use the custom gcc-4.8 to build my test program ... – Alex Jul 22 '14 at 17:34
