build a file.lib to a file.a usable on linux

问题:

I'm trying to port a api from windows to linux. So far I've done the work on file.cpp and file.h but I still have a library .lib specified to windows that is needed in order for the api to work. how can I build a file.a usable on linux from this library?

Static libraries in Linux (or all POSIX systems, like Mac OSX) are actually archives containing all object files. These archives are created with the ar command:

ar crv some_library.a some_object_file.o

The above command creates the "archive" (i.e. static library) some_library.a from the object file some_object_file.o. This library can now be used when linking other programs.
