[GRASS5] OpenGL GL/gl.h not found and fftw

DrakeGis · August 17, 2004, 10:35pm

Hi,
  I'm compiling grass 5.7.0 from the sources and I'm unable to find how to
include OpenGL.
   I tried "--with-opengl-includes=/usr/X11R6/include/" because gl.h
"lives" in /usr/X11R6/include/GL/ but I received a message that gl.h is
not available.
   I'm using Debian SID, and I also have the xlibmesa packages installed
on my system.
   Does anybody knows which are the correct flags ?

By the way I'm very curious about what is for "fftw".

Thanks

D.

You shouldn't need additional switches; the X switches are added
automatically for the OpenGL checks.

If the <GL/gl.h> check fails, it's usually because preprocessing that
file generated either error or warning messages. Look in the
config.log file which configure creates; there should be a couple of
lines like:

configure:9725: checking for GL/gl.h
configure:9733: gcc -E -I/usr/X11R6/include conftest.c >/dev/null 2>conftest.out

If any error/warning messages were generated, they will follow.

BTW, if you have installed nVidia's OpenGL package, you need to delete
(or move) the headers, as they are known not to work.

By the way I'm very curious about what is for "fftw".

FFTW is a Fast Fourier Transform (FFT) library. It is used by the
programs i.fft, i.zc, i.shape and r.surf.fractal. If you don't need
these programs, you can use --without-fftw. Otherwise, you need FFTW
2.x installed (neither 1.x nor 3.x will work); see www.fftw.org for
more information.

Use 'apt-file search gl.h' to find what package it comes from:

Are the xlibmesa-gl-dev and xlibmesa-glu-dev packages installed?

GRASS 5.7 config for Debian:

get latest CVS version of GRASS 5.3
get latest CVS version of GRASS 5.7

CFLAGS="-march=pentium4 -Wall" ./configure \
    --with-grass50=/usr/src/grass/grass53 \
    --with-tcltk-includes=/usr/include/tcl8.3 \
    --with-postgres-includes=/usr/include/postgresql \
    --with-motif --with-motif-includes=/usr/X11R6/include \
    --with-readline --with-gdal --with-cxx --with-glw \
    --with-freetype --with-freetype-includes=/usr/include/freetype2 \
    2>&1 | tee config_log.txt

make mix
make

To run GRASS 5.7, simply start
./bin.$ARCH/grass57

You can now use the GDAL and PROJ packages from Debian to compile GRASS.

By the way I'm very curious about what is for "fftw".
