Re: [ruby-fltk-users] Anyone managed to compile under OS X?

Rob, 

I'm the current maintainer of Ruby/FLTK but I'm not one of the
original developers.  Unfortunately I only have access to Linux so I
can't debug your problems directly.

It looks like the all tests for headers pass but the ones for
individual functions fail.  This may be because your compiler is
trying to compile the test files as C instead of C++.  extconf.rb
redefines the test file to have a .cxx extension and relies on the
compiler to know that this means the contents are C++ .  This works
with gcc , but maybe your compiler behaves differently.

There's a line in extconf.rb that does this whenever the platform is
not X11 or Windows.  I assume you're not running X11 on Mac OS?

Can you send the mkmf.log file?  That should record exactly what the
compiler was doing when the feature tests failed.  Did you get as far
as running make?  If so, can you send the log of that too?

It's very annoying that the mkmf feature test functions fail for C++
and that there is no standard, reliable fix for this, or at least
there was none when I last tapped Google and the lazyweb for answers.
I'll look again and see if things have improved.
