I have a program written on C which compiling without problems on Linux and Snow Leopard. Some days ago I embedded lua and after that I got some prolems. On Linux I compile now with LDFLAGS = -llua in makefile. I also added the same for Makefile on Mac. But now on Mac I got this errors: Code: > CC=gcc-4.0 make arch=i386 Undefined symbols: .... ld: symbol(s) not found collect2: ld returned 1 exit status Whats the problem? Lua compiled from sources for i386 arch. (Compiled for x86_64 - same problems) Thanks, any help is much appreciated.
