perl 5.36 cpan | OpenGL fails tests

[shawnlaffan]

As noted in #93, OpenGL is failing its tests under gcc-13. This has not been fixed by the vmem patching that gets PDL to build.

OpenGL is currently disabled in the build system so opening this issue to flag it as a known issue.

For me, the 3 test scripts in the "t" folder all pass when run as perl -Mblib t/<script.t>.
But those tests don't get run under gmake test because test.pl aborts isomewhere inside glutMainLoop().

Is that the issue we have to deal with ?

I don't know to what extent it's a problem, but I notice there's a glutCloseFunc() call inside test.pl even though I can see it reported in the test.pl output that glutCloseFunc: not implemented.

IME it doesn't matter how many graphics libraries you repair - there's always one more that demands fixing ;-)

Yes, that's the issue.

And now I have searched a little harder I found the previous discussion of this in some code comments, starting at 409d29b#r110340879

I'll generate the gdb backtrace once I have a 5.36 with a working gdb.

I see that the freeglut developers no longer provide a Configure script. I presume we need to use cmake.
I assume you are building freeglut-3.4.0.
If you care to share the mantra that will build, test and install freeglut, I'll give it a go. (It's not of great importance to me, so feel free to ignore.)

I'm a little curious to see if 32-bit builds of OpenGL-0.70 are similarly afflicted.

Yes, it's 3.4.0. Build is at:
