[Kaffe] problem with bad libgif link in CVS code

[Moses DeJong]

Hi all.

I had a big problem with kaffe out of todays CVS. I was running on a
solaris sparc 5.6 system when I ran into a problem with libgif. The
configure script seemed to think libgif worked and it linked Kaffe
to it, but when I ran the code it crashed.

I could not find libgif on my system and I had no clue how to fix the
configure.in script so I just tossed a hack into configure so that the
contest compile failed. After installing I now had no link to libgif.

checking for DGifOpenFileHandle in -lgif... no

        libdl.so.1 =>    /usr/lib/libdl.so.1
        libmp.so.2 =>    /usr/lib/libmp.so.2



That worked for me but it seems like the configure script should be
able to figure out that no libgif exists on my system.


I hope that helps
