I've worked on a t4k_common.mk, and gotten t4k_common to build and
install (apparently) successfully.  However, when I try to then build
tuxmath using t4k_common, I get a bunch of  "undefined reference"
errors arising from the code in t4k_common.  E.g., when a file in
t4k_common calls a function from SDL_Pango, it results in an undefined
reference error, which only shows up at the stage where tuxmath,
t4k_common, and all the dependencies are statically linked together.
Looking at the final gcc invocation in the make process, the needed
linker arguments (e.g. "-lfoobar") are indeed missing.

I can supply the exact files and output, but I'm looking more for
general knowledge than for someone to fix my specific issue for me.

So how is a lib in mingw-cross-env supposed to supply the arguments so
that all the libs it needs will be found?

(pardon my newbiehood, and feel free to point me toward a relevant fine manual).

Thanks for any help,
