Your suggestion works! Now, I extend my test program to generate a dynamic library. However, when I use g++ to link, I got the following error $ g++ -g -Wall -dylib bin_osx/osServDarwin.o bin_osx/utilsDarwin.o bin_osx/nlstrDarwin.o bin_osx/nlthreadDarwin.o bin_osx/nlthreadpool.o -o bin_osx/libcebrain.dylib -lpthread -liconv /usr/bin/ld: Undefined symbols: _main collect2: ld returned 1 exit status Could you tell me if where I did wrong again? Under this case, do I have to use ld instead? (Hope not, otherwise, it is hassle to write my general makefile to specify what linker used for dynamic library and for executable differently.)
