Package: libegl-mesa0
Version: 20.3.5-1
Severity: important
File: /usr/lib/x86_64-linux-gnu/libEGL_mesa.so.0.0.0
Dear Maintainer,
When testing version 2019.1 of the Schrödinger suite we found a bug in 3 of the
packages belonging to Mesa; libgbm1, libglx-mesa0 and libegl-mesa0 (reported as
separat bugs)
We got the following error message
libGL error: MESA-LOADER: failed to open swrast:
/usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or
directory (search paths
/usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGL error: failed to load driver: swrast
The '\$' preceding '${ORIGIN}' does not seem right.
After running a script that checked all files in /lib, /lib64, /usr/lib and
/usr/libexec
we found 3 files containing the string '\$${ORIGIN}/dri'.
/usr/lib/x86_64-linux-gnu/libgbm.so.1.0.0 (from libgbm1/now 20.3.5-1 amd64)
/usr/lib/x86_64-linux-gnu/libGLX_mesa.so.0.0.0 (from libglx-mesa0/now
20.3.5-1 amd64)
/usr/lib/x86_64-linux-gnu/libEGL_mesa.so.0.0.0 (from libegl-mesa0/now
20.3.5-1 amd64)
The string is compiled inte the lib itself, it is not found in the ELF-header.
The easiest way to check if the bug is present is with
grep -a '\\\$\$\{ORIGIN\}/dri' <lib>
We have tested a binary patch as follows:
cd /usr/lib/x86_64-linux-gnu
cp -p libEGL_mesa.so.0.0.0 libEGL_mesa.so.0.0.0.ORIG
cat libEGL_mesa.so.0.0.0.ORIG | sed -e
's/:\\$${ORIGIN}\/dri:/:\/:${ORIGIN}\/dri:/' > libEGL_mesa.so.0.0.0
(and corresponding to the files from the two other packages).
With that patchs we can start the Schrödinger suite without any errors. Other
software that we have tried and that use Mesa also work without complaint after
we patched.
The occurrence of $$ is found in the newer version 22.2.0-1 as well.
