I used it to convert static library, and it says the input library is not import library.
That's coffimplib. coff2omf is in the Extended Utilities Package which is sold for 15$.
Many existing C libraries are not written as dynamic libraries. Some C libraries can be compiled as DLL, but in performance critical application, such as games, they must use static link to increase performance. I hope there is a good solution for linking C static libraries.
Well maybe Walter will give away coff2omf (and maybe obj2asm too) for free some day to solve this problematic situation.
As I said, either you buy coff2omf, try objconv or compile with dmc.
