go-fltk's Issues
install tries to download fltk-2.0.x-r7725
=fltk-2.0.x-r7725 is no longer on the website
get a 'not found' error
build failure FC12 AMD64
cloned the repository (a few minutes ago, 22Nov2010 13:20ish), did a make install. Make downloads fltk and starts compiling. All is well until:
g++ -Ifltk-2.0.x-r7725 -c fltk.cxx
g++ -m64 -o cgo_fltk.so fltk.cgo2.o widget.cgo2.o group.cgo2.o input.cgo2.o texteditor.cgo2.o window.cgo2.o fltk.o fltk-2.0.x-r7725/lib/libfltk2.a -lXext -lXinerama -lXft -lX11 -lXi -lm -shared -lpthread -lm
/usr/bin/ld: fltk.o: relocation R_X86_64_32 against `typeinfo for EventStealer' can not be used when making a shared object; recompile with -fPIC
fltk.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
Happy to try recompiling with -fPIC if someone can tell me where/how to add it.
Running Fedora Core 12, system update as of this morning, on an AMD64-style system.

Doesn't build undir Windows using mingw32
Hi, I succeeded building go-fltk and examples on windows box by slightly tweaking the makefile, but when I try to run examle I get the following panic error.

I suppose the problem is that something is not compiled or linked as it should?
Here are my modifications to makefiles:

What happened to Gober?
What happened to the Gober editor that's linked to? It 404s. Very curious.
