C Question

fltk complains about gcc on windows

I've been trying for almost a to build

on windows in so many different ways but I always end up with:

configure: error: C compiler cannot create executable
(msys fltk/configure)


Check for working C compiler: C:/MinGW/bin/gcc.exe -- broken

I've tried it with
fltk 1.3.0
and I've even used three different MinGW distros,
. Yet it just won't compile. Here is some of the error log generated by the ./configure file:

$ ./configure --prefix=C:/libs/fltk-1.3.3


Core tests.

I previously compiled 2 other gui libraries with these same tools (nana and SFML), so there can't be anything wrong with the gcc compilers.


Something (most probably
) keeps breaking my
program and every time its "broken" I get black vcc1.exe windows. Then I must replace the mingw folder to get it working again, this happens mostly when I open netbeans. I just don't know how to fix this, so I've just been avoiding

Answer Source
  • I was finally able to build it yesterday with this version of TDM-GCC (as per the gui installer):
    • MinGW-w64/TDM64 (32-bit and 64-bit) ==> TDM-GCC
  • I used he cmake gui instead of the .configure
    1. open cmake gui.
    2. input the source code folder (root of fltk folder, ie: "C:/libs/fltk-1.3.3").
    3. input the build folder, ie: "C:/libs/fltk-1.3.3/build/".
    4. click configure
    5. ** optionally you can change some options but i didn't
    6. click Genertae
    7. in cmd (I used git bash though): cd to the build directory and run make or mingw32-make

  • I completely uninstalled cygwin because of its interference with the tool chain builds, i.e mingw and tdm-gcc (Still not sure why this happens).
