GLError 1285

GNU Radio

I have users of my simple_ra application complaining of this:

Traceback (most recent call last):
File
“/usr/local/lib64/python2.7/site-packages/gnuradio/wxgui/plotter/plotter_base.py”,
line 209, in _on_paint

(src/errorchecker.c:1218)
OpenGL.error.GLError: GLError(
err = 1285,
baseOperation = glCallList,
cArguments = (1L,)
)

After running for an hour or two.

This is on F22, but on F20, there’s no such issue. So, it appears that
there’s a memory leak somewhere, but not sure where.

Hi,

OpenGL_accelerate.errorchecker._ErrorChecker.glCheckError
there’s a memory leak somewhere, but not sure where.
I’d suspect the driver …

What hardware are they running this on ? (which GL driver)

Cheers,

Sylvain

Here’s info from one of the users:

Thanks for reporting the error on the mailing list.
To answer Sylvain, here’s the chipset and Mesa driver I’m using. I
suspect Dave also uses an Intel chipset.

$ dnf list installed | grep -i mesa-dri-drivers

I’m not a subscriber on the mailing list and I’m unknown there, maybe
you could forward them this.
If some debug info is required such as an strace, I’ll subscribe to
their list and deal with them directly.

Damien
