[OTR-dev] gaim-otr for windows followup

[Paul Wouters]

Bah, so close :)

So I got libgcrypt.dll using a mingw cross compiler setup. I should probably
diff my tree by now, as there are a few changes to make it compile. Google
should know it too, since all you find out there are the same questions,
from two years ago even, asking for a libgcrypt.dll.

The next step was to add it to the windows gaim plugin source dir. Sicne
that's a rather large built, I figured it was better to try and cross
compile gaim-otr too.

So I started to try and cross compile it.

[ etc etc etc ]

This is where I decided to stop for today and go back to book work :)

Does gaim-otr do any networking things itself? I really hope not, since
those would have to be ported to winsock2.h calls.

Also, I didn't set RANLIB, AR, AS or LD. Since autoconf is used to create the
makefiles, perhaps I've just missed a few more cross compile settings. But
regardless, any calls to 'gcc' or 'ranlib' etc, should check for these
environment variables properly. LDFLAGS might need the same 'override' syntax
as CFLAGS got.
