========================
Installing POGL (OpenGL-0.58_003):
$perl Makefile.PL
glversion.c:13:21: error: GL/glut.h: No such file or directory
freeglut3 2.4.0 package was already installed, so I added the -dev
package. This had a bunch of other -dev dependencies, X & mesa & the
like. I understand from the POGL docs that headers might not be
required since they come with the module, but thought it might be useful
anyway.
$ perl Makefile.PL verbose
$verbose set to 1
found libs:
GL = 'GL'
GLU = 'GLU'
GLUT = 'glut'
GLX = 'glx'
Testing for OpenGL Extensions
Testing GLUT version
glversion: cd utils;make -f Makefile GLUT_LIB=glut GLUT_DEF=HAVE_GLUT
clean;make -f Makefile GLUT_LIB=glut GLUT_DEF=HAVE_GLUT
/usr/bin/ld: cannot find -lXi
collect2: ld returned 1 exit status
make: *** [glversion] Error 1
It can't find -lXi, but /usr/lib/libXi.so.6->/usr/lib/libXi.so.6.0.0
exists.... ah, but for some reason there's no symlink libXi.so
->libXi.so.6, so I added that. Similar problem and solution for -lXmu.
After that the Makefile was created just fine.
make was slow on my 4-year-old $300 desktop, but finished successfully.
make test was fun!
The only thing that didn't work as expected was that hitting the 'f' key
didn't toggle the FBO field, whatever that does. Otherwise rotation,
lighting, zooming, blending, etc worked fine. It went into fullscreen
mode just fine, but didn't come out of it so well. After closing the
window I had to drag my emacs window over some black spots it left on
the screen. But maybe that's just my crummy integrated graphics not
being able to handle all that.
make install was fine. I haven't installed OpenGL::Image or
OpenGL::Shader yet.
========================
Building PDL-2.4.4_09git pogl-merge branch
I moved my ~/.perldl.conf out of the way so it would use the one in the
git repo. Makefile and make were fine.
make test said:
t/vaffine...................ok
t/xvals.....................ok
All tests successful.

and then did the subdirs-test target:
