CMake refuses to find OSG on Debian testing

[Antsan]

I'm having a problem with the recommended way to compile OMW. I am on Debian testing 64bit.

That is, I cloned both open-mw and the openmw-specific version of osg. When running cmake on osg, I get the following warning:

Code: Select all

The build system is configured to install libraries to /usr/local/lib64
Your applications may not be able to find your installed libraries unless you:
    set your LD_LIBRARY_PATH (user specific) or
    update your ld.so configuration (system wide)
You have an ld.so.conf.d directory on your system, so if you wish to ensure that
applications find the installed osg libraries, system wide, you could install an
OpenSceneGraph specific ld.so configuration with:
    sudo make install_ld_conf

So I run

sudo make install_ld_conf

, compile and install osg, and then proceed do open-mw itself.

When running cmake on open-mw I am told that osg has not been found:

I have no idea how to either tell osg to be installed somewhere where cmake can find it[1] or how to tell cmake in open-mw where to find osg.

Information on cmake I find seems all to be about how to use cmake as a developer.

[1] It's a warning by cmake. Why doesn't that tell me how to do this?

Have you tried running `sudo ldconfig` after installing the new ld configuration file?

[Antsan]

Yep, doesn't change a thing.

[scrawl]

Ok, then the next thing I would check is: do you have /usr/local/lib/pkgconfig in your list of pkgconfig search paths?

Code: Select all

pkg-config --variable pc_path pkg-config
/usr/local/lib/x86_64-linux-gnu/pkgconfig:/usr/local/lib/pkgconfig:/usr/local/share/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/lib/pkgconfig:/usr/share/pkgconfig

If not, then preprend a PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH before the cmake call.

Edit: ignore what I just wrote, FindOSG doesn't even use pkg-config.

[scrawl]

Try this, then:

Code: Select all

cmake -DCMAKE_LIBRARY_PATH=/usr/local/lib64 <path/to/openmw_sources>

[Antsan]

Yay! This seems to have done the trick. cmake went through without errors. make is doing its thing right now.

Thank you very much!

Just wanted to chime in that later versions of cmake don't work with this suggestions, instead you can suggest this: -DCMAKE_SYSTEM_PREFIX_PATH=<path to lib>
