yorick-gl: OpenGL 3D graphics support for the Yorick language

[paumard]

Hi,

This is the OpenGL wrapper for Yorick.

Yorick is submitted: 24768.

To test this port, install it, launch yorick (preferentially with "rlwrap yorick"), and at the yorick prompt type:

#include "testgl.i"
testall3d, 32
quit

Regards, Thibaut.

PS: I have noticed a strange behavior:

port install yorick-gl
port uninstall yorick-gl
port install yorick-gl

fails with:

Error: Target org.macports.activate returned: Image error: /opt/local/lib/yorick/i/contour.i already exists and does not belong to a registered port.  Unable to activate port yorick-gl.
Error: Status 1 encountered during processing.
Before reporting a bug, first run the command again with the -d flag to get complete output.

I really don't understand why since "port -d uninstall yorick-gl" does:

[...]
DEBUG: deactivating file: /opt/local/lib/yorick/i/contour.i
[...]
DEBUG: Removing entry from file_map: /opt/local/lib/yorick/i/contour.i
[...]
DEBUG: uninstalling file: /opt/local/var/macports/software/yorick-gl/1.1.0.cvs20100504_0/opt/local/lib/yorick/i/contour.i
[...]

and after that:

ls: /opt/local/lib/yorick/i/contour.i: No such file or directory

Replying to thibaut.paumard@…:

Error: Target org.macports.activate returned: Image error: /opt/local/lib/yorick/i/contour.i already exists and does not belong to a registered port. Unable to activate port yorick-gl.

Agreed, looks like yorick-gl is not DESTDIR-aware. I'll patch its Makefile using the method used by another of the yorick ports that are DESTDIR-aware.

Committed the port in r67913 with these changes:

• changed mesa dependency from lib:-style to port:-style (we always want to use libGL from MacPorts mesa; we never want to use another libGL the user might have coincidentally installed somewhere)
• removed xorg-libXext dependency (xorg-libXext is already in mesa's dependency chain)
• patched configure script to only look for GL files in ${prefix}; even without this patch yorgl.so ended up linked with ${prefix}/lib/libGL.1.dylib like it's supposed to, but the output of the configure phase said it had found something in /usr/X11R6 and I wasn't comfortable with that
• patched Makefile to be DESTDIR-aware using technique adapted from yorick-yutils
• disabled universal variant
• whitespace and formatting changes
