Something is awry in your build - if you have correctly set things up for 32 bit builds, why is the error talking about x86_64? Once you figure that out I'd guess that all will be well. > which makes me wonder if I cant use 1.3 for a 32 bit build.

The error you flagged would suggest that you have a mix of 32-bit and 64-bit stuff going into your final object, and it is that which is causing the problem. Once you clean things up to be either all-32-bit or all-64-bit I'd expect things to go a lot more smoothly. I can't tell you how to do that, as I have no idea what tools or system you are on, and the tweaks necessary to persuade any given build system to do the Right Thing can tend to be a little platform specific... However, rest assured that others are doing this and it Just Works, so you should be fine! _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
