Bug#1031189: libogre-dev: Does not automatically derive plugin path

2023-02-15 Thread Matthew Fennell 
Sorry for wasting your time, I think I was wrong to raise this bug and it can be
closed.

I see that /usr/lib/x86_64-linux-gnu/OGRE/cmake/OGREConfig.cmake defines
OGRE_PLUGIN_DIR, and that this path contains a plugins.cfg file that includes
the correct PluginFolder filepath.

Therefore, no magic is required - I simply needed to pass this variable to my
application.

Thanks again for maintaining this package - and thanks also Andreas for
moving on my report to the correct list,
Matthew

Bug#1031189: libogre-dev: Does not automatically derive plugin path

2023-02-12 Thread Matthew Fennell 
Package: libogre-dev
Version: libogre-1.12-dev
Severity: normal

Dear Maintainer,

libogre-1.12-dev installs Ogre plugins to /usr/lib/x86_64-linux-gnu/OGRE -
however, by default, Ogre is not searching in this directory when loading
plugins at run time.

matthew@matthew-laptop:~$ ls 
/usr/lib/x86_64-linux-gnu/OGRE/RenderSystem_GL.so.1.12.10
/usr/lib/x86_64-linux-gnu/OGRE/RenderSystem_GL.so.1.12.10

When I try and load RenderSystem_GL using:

root.getRenderSystemByName("OpenGL Rendering Subsystem");

I see that Ogre searches the following locations:

But cannot find the library in any of these paths, and throws the following
exception:

C++ exception with description "InternalErrorException: Could not load dynamic
library RenderSystem_GL.  System Error: RenderSystem_GL.so.1.12.10: cannot open
shared object file: No such file or directory in DynLib::load at
./OgreMain/src/OgreDynLib.cpp (line 113)" thrown in the test body.

I can work around this by adding:

PluginFolder=/usr/lib/x86_64-linux-gnu/OGRE

to the top of my plugins.cfg file. But, I was wondering if it would be possible
for the package to allow Ogre to derive the correct search path automatically -
perhaps using rpath?

Thanks for maintaining this package.
Matthew
