enblend 3.0 fails to build / glut-related

[michael@…]

Hello everyone,

For some while now I can't build the enblend port. Today I have updated my Macports tree and updated all installed ports, but enblend still fails to build with glut.h-related messages. The system is MacOSX 10.5.6 and Macports 1.7

The Portfile for enblend is: # $Id: Portfile 47383 2009-02-27 20:59:18Z jeremyhu@… $

$ port outdated No installed ports are outdated.

$ port clean --all enblend

$ port -dcuv install enblend --> See attached Transscript.

I see the same problem. This looks like an X11 issue. I'm Cc'ing Jeremy on this in case he has some insight.

Last year I started toying around with enblend (and the - then new - enfuse). I never got the GPU support to work properly, so I usually disabled it. My main focus back then was creating a "standalone" version, I tried to ​document that. I didn't explore that any further, as some things started to fall apart (mainly because of non-working universal variants).

With a few tweaks (the cd command is no longer supported) I was able to build a current CVS snapshot with my portfile. I'm attaching a diff for the portfile, which should bring the enblend port to version 3.2, including enfuse. I'm not a programmer, so maybe someone more savvy with TCL and the MacPorts system should have a look at it. I don't have GLUT and GLEW installed, so the configure script disables those options automatically. There should be some explicit configure.args-append directive for that (I didn't try --without-glut or --without-x).

This doesn't solve the problem with GLUT and GLEW mentioned in this ticket, but it should enable people to build a working enblend (and enfuse). Did anybody try the GPU-enabled versions and do they really speed up blending/fusing?

Patch to update enblend-3.0 to enblend-enfuse-3.2

This isn't really an X11 issue.

The problem is that it's trying to use a CGL libGLEW and a GLX libGL and libglut.

My suggestion is to change the glew port to have a no_x11 variant to install the CGL version and provide a GLX version by default.

Or we should rename the glew port to something like glew_cgl and just bump the version of mesa to 7.3 which will provide glew (I wanted to wait for 7.4 for this though)
