 You will also need to set LIBGL_DRIVERS_PATH

FWIW, I recommend using single quotes around $LIB:

LD_LIBRARY_PATH='/some/chroot/usr/$LIB/'
LIBGL_DRIVERS_PATH='/some/chroot/usr/$LIB/dri'

Otherwise the shell will substitute it with the wrong thing.

A few things that come to mind:

a) A 32/64 bit issue

For example: one is pointing to 32bit binaries, while 64bit ones are
needed, or vice-versa.

Have _both_ present and use $LIB. The variable will expand accordingly
- be that lib, lib32, lib64, lib/x86_64-linux-gnu or other

b) Missing/wrong dependency - libstdc++, llvm, other
The debug hints below will help here.


Note that the issue (one here or bugzilla) can be in either the
frontend libraries or the backend DRI driver.

* For normal libraries - libGL/libEGL/libglapi, libgbm
LD_LIBRARY_PATH=/some/chroot/usr/$LIB/
to debug
LD_DEBUG=libs

* For the backend DRI module - foo_dri.so
LIBGL_DRIVERS_PATH=/some/chroot/usr/$LIB/dri
to debug
LIBGL_DEBUG=verbose

I'd start with setting all of the above and getting things to run.
Next step is to track if it's a frontend or backend issue.

Note: ensure that the configure/build options haven't changed. Or
check that that their change isn't causing the bugzilla issue.

Sorry I kind of mixed that up, you should also set LD_LIBRARY_PATH to
use the mesa libraries related to the drivers. This will probably do: 

LD_LIBRARY_PATH= \
/home/user/mesa-dri-drivers-18.0.0-0.1.rc4.fc27.x86_64/usr/lib64

Maybe it is a typo? I already mentioned LIBGL_DRIVERS_PATH in my message

[Mesa-dev] PATH(s) to run Firefox with different Mesa versions

2018-03-05 Thread Germano Massullo 
Good day
I am testing Firefox with various Mesa versions to find which version
started triggering the bug
<>
https://bugs.freedesktop.org/show_bug.cgi?id=104216

I packaged Mesa 18 for Fedora 27
https://copr-be.cloud.fedoraproject.org/results/germano/mesa_18/fedora-27-x86_64/00720216-mesa/
and then I unpacked
mesa-dri-drivers-18.0.0-0.1.rc4.fc27.x86_64.rpm
and runned Firefox with command
LIBGL_DRIVERS_PATH=/home/user/mesa-dri-drivers-18.0.0-0.1.rc4.fc27.x86_64/usr/lib64/dri/
firefox

Question: is LIBGL_DRIVERS_PATH enough to let Firefox use a different
Mesa version?
I am asking this because on the console I am getting

libGL error: unable to load driver: radeonsi_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: radeonsi
libGL error: unable to load driver: radeonsi_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: radeonsi
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast
libGL error: unable to load driver: radeonsi_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: radeonsi
libGL error: unable to load driver: radeonsi_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: radeonsi
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swras
