Re: [Openexr-user] exrdisplay compile woes on Redhat 7.3

[John Coldrick]

        Thanks Drew and Paul for getting back.  Couple of quick things:

        This has been happening for a couple of releases now.
        I've been able to replicate Alec's problem too but the fix Drew
suggested didn't work for me(prob a syntax error on my part :P ).
        I've had the same problem with fltk 1.1(only tried 1.2 because I
thought this might solve things ;) ).
        I've compiled fltk with the same compiler.
        GL got successfully compiled with fltk.
        I'm starting to get *really* frustrated with gcc 2.96.  ;)


        Anyway - I'm in agreement that the problem lies with configure + gcc
2.96(running 2.96-113 btw).  I'm a little hesitant to start drawing you
guys into a contracted debug session because my coding skills are
minimal and you both have fulltime jobs...;)  Essentially the problem
seems that it's not finding fltk and I'm not sure, syntax-wise, where I
can manually place the default fltk include dir into the mix.  Note that
I used the 

        --with-fltk-config=/usr/local/bin

        flag with configure but I assume this is what's busted with the
compiler/precompiler?

        With the exrmakepreview(the only other thing that won't compile), I
added the include, and changed line 85 to:

return (unsigned char) (clamp (Math<float>::pow () (x, 0.4545f) *
84.66f, 0.f, 255.        f));


        and I get:

        Anyway - I'll cut it there since I appreciate free support emails
;)...I haven't packaged an rpm before - is that a reall hassle to do? 
Those courtesy binaries always worked fine for me...

        Many thanks...

        Cheers,

        J.C.
