Problem with fonts in Emacs

xset +fp /usr/X11R6/lib/X11/fonts/100dpi 
xset +fp /usr/X11R6/lib/X11/fonts/75dpi 
xset fp rehash

Permanent solution: add the following lines to /etc/X11/xorg.conf as root (under the "Files" section):

FontPath "/usr/X11R6/lib/X11/fonts/100dpi"
FontPath "/usr/X11R6/lib/X11/fonts/75dpi"

Install Coin3D with Simage

Simage:

• Download simage 1.6.1
• 'configure'
• 'vi libtool'
• comment out the line starting with "predep_objects" to avoid multiple definition errors
• 'make'
• 'make install'

Coin3D:

• Download Coin3D 2.5.0
• 'configure --disable-dl-simage'
• make sure simage is listed to be statically linked, not at run-time
• 'vi Makefile'
• in line starting with 'CC' add '-fPIC'
• to avoid linker problem with libGL.so:
  • 'su'
  • mv /usr/lib/libGL.so /usr/lib/libGL.so.bak
  • ln -s /usr/lib64/libGL.so /usr/lib/libGL.so
  • exit
• Download Zlib 1.2.3
  • 'vi makefile'
  • edit the line starting with 'CC': add -fPIC
• 'make'
• copy libraries to extern_libs/lib64
• Undo change to libGL.so:
  • 'su'
  • mv /usr/lib/libGL.so.bak /usr/lib/libGL.so
