I have pkgconfig installed, I had to update the env variable but I did get the flags. So xcode uses this compile line

/Developer/usr/bin/g++-4.0 -arch i386
-L/Users/MacBook/Code/testing/build/Debug -F/Users/MacBook/Code/testing/build/Debug -F/Developer/Library/Frameworks -filelist /Users/MacBook/Code/testing/build/testing.build/Debug/testing.build/Objects-normal/i386/testing.LinkFileList -L/opt/local/lib -L/usr/local/lib -lgretl-1.0 -lxml2 -lpthread -lz -liconv -lm -framework TALib  -o /Users/MacBook/Code/testing/build/Debug/testing
Undefined symbols:
  "libgretl_init()", referenced from:
      _main in main.o
  "libgretl_cleanup()", referenced from:
      _main in main.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

specifically I added -L/opt/local/lib -L/usr/local/lib -lgretl-1.0 -lxml2 -lpthread -lz -liconv -lm  based on the result from pkgconfig. And I have confirmed libgretl-1.0.0.dylib is in /usr/local/lib

Thanks again!

Joel
