Re: octave build issue -- error in fltk-backend.

[Alonso Escobar]

Me too!, I've got the same problem. I'm running on a:

CPU: Turion 64 x2 TL-60
gcc/gfortran 4.4.1 (latest available at the Mandriva reposteries )
OS :  Mandriva 2010
fltk:  1.3.x-r7677 (just compiled, "fluid" works )

Flags for the C++ compiler:
-O3 -fno-tree-vectorize -pipe -march=native -mmmx -msse -msse2 -msse3
-m3dnow -fopenmp
(nothing to do with th flag of Imam Toufique)

After the installation failed, I changed the path of the #include files in
"fltk_backend.cc" to the whole path, i.e. :
#ifdef HAVE_CONFIG_H
#include </home/jalorer/octave-3.3.52/config.h>
#endif

#if defined (HAVE_FLTK)

#include </usr/include/c++/4.4.1/map>
#include </usr/include/c++/4.4.1/set>
#include </usr/include/c++/4.4.1/sstream>
#include </usr/include/c++/4.4.1/iostream>

#include </usr/include/FL/Fl.H>
#include </usr/include/FL/Fl_Window.H>
#include </usr/include/FL/Fl_Output.H>
#include </usr/include/FL/Fl_Button.H>
#include </usr/include/FL/Fl_Box.H>
#include </usr/include/FL/Fl_Gl_Window.H>
#include </usr/include/FL/fl_ask.H>
#include </usr/include/FL/fl_draw.H>
#include </usr/include/FL/gl.h>

#include "/home/jalorer/octave-3.3.52/liboctave/cmd-edit.h"
#include "/home/jalorer/octave-3.3.52/liboctave/lo-ieee.h"

#include "/home/jalorer/octave-3.3.52/src/defun-dld.h"
#include "/home/jalorer/octave-3.3.52/src/error.h"
#include "/home/jalorer/octave-3.3.52/src/gl-render.h"
#include "/home/jalorer/octave-3.3.52/src/gl2ps-renderer.h"
#include "/home/jalorer/octave-3.3.52/src/graphics.h"
#include "/home/jalorer/octave-3.3.52/src/parse.h"
#include "/home/jalorer/octave-3.3.52/src/toplev.h"
#include "/home/jalorer/octave-3.3.52/src/variables.h"

(of course I verified that all of them existed)
and rerun the command that failed:
/bin/sh ../libtool  --tag=CXX   --mode=compile g++ [...] -f
'DLD-FUNCTIONS/fltk_backend.cc' || echo './'`DLD-FUNCTIONS/fltk_backend.cc 

But i got the same errors.

Also, Before trying with fltk 1.3.x-r7677, I was tying with the latest fltk:
v. 2.0.x-r7680. The "configure" script didn't recognise it a first because
instead of installing "fltk-config" it installs "fltk2-config" (and it
doesn't copy the "FL" directory directly /usr/include, but into
/usr/compat/include, or something like that ), anyways, I symlinked
"fltk-config" to "fltk2-config" and moved (or symlinked, can't remember)
"FL" to the same position as the old version (so the final path was
"/usr/include/FL"), but the installation of Octave failed, although with
another error:

Error 1
make[3]: Leaving directory `/home/jalorer/octave-3.3.52/src'

in this case I didn't try changing the path of the #include files to their
absolute paths. Also, as you can see,  I wasn't using any optimization
flags.

Any help will be greatly appreciated, thanks.
