Re: [Mingw-users] adding my own libraries to mingw

[William S. <wil...@gm...>]

The problem below I have no idea about. I tried my own ugly makefile
(which I showed you before). It worked, but make seemed confused about
what directory it was in! It claimed it couldn't find librand.a (to
move) or rand.o (to delete). So I did those things by hand.

Then I compiled my test program that used my rand library. Before that
I told you that I edited the specs file as instructed. Worked!

So the two mysteries are
- those weird messages I got when doing a make of the library with the
nice makefile
- the fact that make got confused about what dir it was in when using
my ugly makefile

Thanks for any help!
