build issues with cmake (on debian bullseye)

[GeraldJansen]

With a fresh clone of current master, installation fails because libhamster.so doesn't get created in the make step. Looking a bit closer, I got this:

[build]$ make

[build]$ ls panel-plugin/CMakeFiles/hamster.dir
build.make      cmake_clean.cmake  depend.internal  flags.make  progress.make
C.includecache  DependInfo.cmake   depend.make      link.txt    relink.txt

I'm not sure what those vm.drop_caches = 3 messages are about, but no object files are being created.

I need to update the instructions. The following works for me on debian bullseye:

The fix with 17.1 is that the end install is in /usr/lib/x86_64-linux-gnu/xfce4/panel/plugins/libhamster.so instead of /usr/lib/xfce4/panel/plugins/libhamster.so hard coded but the build itself should not be affected. So called multi-lib-awareness required by fedora, also supported by debian if e.g. 32-bit x86 is enabled.

Thanks for the feedback and new instructions. I followed them but the result is still the same (i.e. no hamster.dir/*.o files created and no libhamster.so created.) I'm still getting the messages about vm.drop_caches = 3 and have no idea what could be triggering them.

[aquaherd]

fired up a podman and built there succeessfully - no idea how to proceed from here on

Perhaps a virtual machine issue? Will build succeed with export MAKEFLAGS=j1 ?

[GeraldJansen]

I must apologize for wasting your time. I had a long forgotten personal alias for cc as a cleancache script :-(

The build and installation works just fine now. Thanks again.

[aquaherd]

No worries.
