MacOSX 10.8 - Undefined symbols for architecture i386:

[oipoistar]

Everything compiles fine but when linking i get the following error message:

Undefined symbols for architecture i386:
"cOAL_CustomStream::cOAL_CustomStream(tStreamCallbacks const&, tStreamInfo const&, void*)", referenced from:
cOAL_Device::LoadCustomStream(tStreamCallbacks const&, tStreamInfo const&, void*)in libOALWrapper.a(OAL_Device.o)
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status


I made sure that each project and product has i386 set. The compiler used is GCC. I am building in Xcode 4.6.2.

I also check the build .a files, unachieved them and used the file command to check if they are i386 or x86_64 and they all are i386. Also the source file which contains the above missing class/method is included in the build sources list.

Well, after wasting hours to fix this and giving up and asking for help it took a few minutes to figure it out. For some reason OAL_CustomStreams.cpp was not included in the project but was present on the drive. I just added it and it now compiles and links just fine.
