[fltk.development] Fltk with VC6 development isn'it possible?
Hi,
This is my first post on Fltk org,
Fltk I find it very interresting but I hope
I will implement it on my VC6 environnement.
So I downloaded fltk-1.1.4 packages with lib and includes
I put in my VC6:
-Project - settings - Link:
fltk.lib wsock32.lib comctl32.lib fltkimages.lib
-Project - settings - Link:
fltk.lib wsock32.lib comctl32.lib fltkimages.lib
-Tools - Option - Directories Includes:
C:\Program Files\fltk-1.1.4
-Tools - Option - Directories Library files:
C:\Program Files\fltk-1.1.4\lib
So I tested with this sample code:
#include FL/Fl.h
#include FL/Fl_Box.h
#include Fl/Fl_Window.h
int main()
{
Fl_Window window(200, 200, Window title);
Fl_Box box(0,0,200,200,Hey, I mean, Hello, World!);
window.show();
return Fl::run();
}
So the results is linking problem:
Linking...
fltk.lib(Fl_Pixmap.obj) : error LNK2001: unresolved external symbol __ftol2
fltk.lib(Fl_Image.obj) : error LNK2001: unresolved external symbol __ftol2

Release/prj_win32cons_fltk.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
prj_win32cons_fltk.exe - 9 error(s), 0 warning(s)
I know that there is a VC6 ide directories on some packages of
Fltk but I must compil fltk.dsw projects and there are severals errors
So I think there is a way without using an existing dsw project,
Could you help me to link correctly my little Fltk program with VC++6 ?
Thank you very much?

And the gcc-based MSYS/mingw toolchain works perfectly on every Windows = variant I've tested it on and has a much more standards compliant and = high-performing compiler than VC6 (currently gcc-4.7.2 I think) and is = free in all the useful ways.

So the results is linking problem: Which seems to be telling us that the binary blobs you downloaded are = not compatible with VC6, if I understand things correctly! Really, you need to be building fltk from official sources - depending = on some old binary blobs is not a good idea.

If you must stick to VC6 (and really, just don't!) then get the = fltk-1.3.2 source and build the fltk libs using the VC6 project that is = built in. Or switch to mingw/MSYS and never look back!
