the build system can't seem to find igdgmm library when linking even though it's under /usr/local/lib directory

Does the build need to know about this library with pkconfig? if so, how can I do that?

CMakeCache.txt

hi @cmsanta please try refreshing dynamic linker sudo ldconfig if it doesn't help then please get cmdline from linking libigdrcl.so and verify if path is correct

ldconfig doesn't help. This is new in 24.13.29138.7. Was fine in the previous release.

ldconfig doesn't help. This is new in 24.13.29138.7. Was fine in the previous release.

Does ldconfig -v list the library?

And if not, is that path in your ldconfig configuration? head /etc/ld.so.conf /etc/ld.so.conf.d/*

[chao-camect]

I have the same issue. It's the same for 24.22.29735.20. the so is in ldconfig -v

[mikamiel]

The problem is that in Ubuntu 24.04 (at least) ld.gold linker is not informed about search path /usr/local/lib (gmmlib library build script installs libigdgmm.so in that dir by default). I didn't find a way to add search path to ld.gold linker in Ubuntu globally or through env variables.

So, to workaround just copy or link file libigdgmm.so into /usr/lib folder.
