What OS are you running on? I've been having the exact same problem you=20
have on my Win98 box, but the same program compiles just fine on the=20
Win2000 systems at my college. The 98 box is running Dev 4.9.8.4, and I'm=
=20
fairly certain the 2000 box is, as well.
I installed the same version of the FLTK DevPack on both systems, and I'm=
=20
using the same linker options. There are a few differences in the=20
compiler log, but I'm not entirely sure why. I've included the logs from=
=20
both compiles below. (Thanks in advance.)
