aven 1.2.3 doesnt run on fedora 16 64 bit linux

[jmbegley]

Running aven on a 64bit linux (fedora 16) laptop only displays an error message "Bug in program detected! Please report this to the authors" and then exits. Running aven from the command line displays:

[james@jumbo ~]$ aven
Bad memory access
[james@jumbo ~]$

Running aven through GDB (with no debugging symbols) gives

(gdb) file /usr/bin/aven
Reading symbols from /usr/bin/aven...(no debugging symbols found)...done.
(gdb) run

Any ideas? version 1.2.2 was working fine ...

1.2.3 is working on my laptop, which is Debian amd64, so I don't think this is a 64-bit issue.

It looks to me like your OpenGL implementation doesn't like glClearColor getting called before OpenGL has been initialised, whereas mine doesn't seem to mind. Can you try the patch I'll attach in a moment?

[Olly Betts]

Call glClearColor after OpenGL is initialised

[jmbegley]

With that patch I get:

[james@jumbo ~]$ aven

The versions of the libGL libraries installed are

[james@jumbo ~]$ rpm -qa | grep GL

[Olly Betts]

fix to not use gl before it is initialised

[Olly Betts]

OK, the new patch should fix that too, and also logs if we try to use OpenGL before it is initialised, to help avoid this issue recurring.

Can you try this one?

[jmbegley]

Yeah, that patch works. Thanks.

[Olly Betts]

Cool, committed as r3921.
