to obtain a cross-compilation of a useful software, MXE refers to a file that contains the string returned by software name, suffixed by .mk(example, fgfs.mk), in the mxe/src/ directory, you must provide this file to allow Makefile generation for software. otherwise, a minimal *.mk file will always return a successful build. | |||
