macOS Help for compiling library with gcc

I m learning compiling and linking of externally build c/c++ library (probably dynamic library ) into xcode project in my workin project

I have to intergrate externally built c/c++ library (probably dynamic library )

my working project suports following architectures
i386 , pcc , pcc64 , pcc7400 , pcc970 , x86_64


I m using gcc for compiling the library

can you tell me gcc command options so that i can link it in in my xcode project

Sample library is in library "src.zip file"
which is to be included in xcode project in "sample xcode project.zip"
