如何在64位OSX上编译GCC 32位应用程序

Question

i try to compile a 32 bit app on my mac osx 64bit

I have a 32bit lib included.

I try to create a personal lib

 gcc -m32 -c fileA.c -Iinclude -o fileA.o gcc -m32 -c fileB.c -Iinclude -o fileB.o 

All Ok

now I create .a File

 ar ruv ./lib/myLib.a fileA.o fileB.o 

When I try to launch

 gcc -m32 -o imageMod imageMod.c -Iinclude -Llib 

I receive the following error

Undefined symbols for architecture i386: "_addozzo", referenced from: _main in imageMod-nfyyGP.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)

anyone can help me?

您需要告诉gcc链接到库中：

gcc -m32 -o imageMod imageMod.c -Iinclude -Llib -l:myLib.a
