I’ve got a dokku droplet that uses OpenGL (via python’s PyOpenGL / pyqt5 & vispy) to create an image. Normally, OpenGL requires a GPU, but I think I’ve successfully compiled the library using mesa for CPU usage.
The issue is my program (deployed via dokku) cannot seem to find the library I created. I compiled the library using the console and put the libGL.so library in /usr/lib .
But when I try LD_PRELOAD=/usr/lib/libGL.so, I get
LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
and then:
libGL.so.1: cannot open shared object file: No such file or directory
which crashes the program.
Is there a place I need to put libraries where dokku can see them?

Hello,
As a test, I would suggest trying to install the libGL with apt rather than comping it manually:
sudo apt update
sudo apt install libgl1-mesa-glx

LD_PRELOAD is set via dokku’s config:
dokku config:set app LD_PRELOAD=/usr/local/libGL.so
