Error with OSMesa LDView

[Travis Cobbs]

Travis,

I updated the version of LDView on my dev server to 4.7 (Built from source using the 4.7 tag on the GitHub repo). 

4.6 (also built from source using the 4.6 tag) works without error. 

4.7 gives the following error:

I verified that the server has libosmesa6 and libglu1-mesa installed. Apparently 4.7 added some other dependency that I can't figure out.

The dev server is Debian 13.

I will investigate.
