Greetings all, I have been using J on linux system (well, all kinds of systems, but linux most commonly). Just about everything has always worked out of the box for me, excepting OpenGL. I didn't worry about it too much until recently.. I don't do a lot of graphics in my work and my personal workstation had a notoriously bad on-board GPU that nothing every really worked on anyhow. I have since upgraded and have a moderately-priced card (GeForce 9500 GT) and all my advanced video functions are working perfectly. Except OpenGL under J
I am running J602 installed by 'j602a_linux32.sh' on an up-to-date 32-bit Fedora 11 $ uname -a "Linux odyseus.local 2.6.30.8-64.fc11.i686.PAE #1 SMP Fri Sep 25 04:56:58 EDT 2009 i686 i686 i386 GNU/Linux" $ grep model /proc/cpuinfo model name : Intel(R) Pentium(R) D CPU 2.80GHz following suggestions found in http://www.jsoftware.com/jwiki/System/Installation/Linux under OpenGL, I seem to have the right libraries: lrwxrwxrwx. 1 root root 10 2009-07-15 21:09 /usr/lib/libGL.so -> libGL.so.1 lrwxrwxrwx. 1 root root 12 2009-07-15 21:07 /usr/lib/libGL.so.1 -> libGL.so.1.2 -rwxr-xr-x. 1 root root 460808 2009-06-12 00:50 /usr/lib/libGL.so.1.2 lrwxrwxrwx. 1 root root 11 2009-07-15 21:09 /usr/lib/libGLU.so -> libGLU.so.1 lrwxrwxrwx. 1 root root 20 2009-07-15 21:07 /usr/lib/libGLU.so.1 -> libGLU.so.1.3.070600 -rwxr-xr-x 1 root root 443900 2009-06-12 00:50 /usr/lib/libGLU.so.1.3.070600 lrwxrwxrwx 1 root root 14 2009-10-19 10:55 /usr/lib/libOSMesa.so -> libOSMesa.so.6 lrwxrwxrwx 1 root root 18 2009-10-19 10:55 /usr/lib/libOSMesa.so.6 -> libOSMesa.so.6.5.4 -rwxr-xr-x 1 root root 2251744 2009-06-12 00:50 /usr/lib/libOSMesa.so.6.5.4 I have a few JREs at my disposal, this is my current default which has worked fine for a lot of other stuff and I use Java a great deal more than most users. $ java -version java version "1.6.0_0" OpenJDK Runtime Environment (IcedTea6 1.6) (fedora-29.b16.fc11-i386) OpenJDK Client VM (build 14.0-b16, mixed mode) I came across Raul Miller's OpenGL test on http://www.jsoftware.com/jwiki/Raul%20Miller/OpenGL ... testogl '' gives me 0 running the components of that verb line-by-line: require 'jzopengl' ogl=.''conew'jzopengl' ogl=.''conew'jzopengl' alloc__ogl 4 4 |makecurrent failed: assert | x assert 0 any further suggestions? -- - michael dykman - [email protected] "May you live every day of your life."
