PCS Failing to Install with RUBY 3.1.2 (Dependency issue)

[ncsrikar]

PCS RPM that comes in the Alma Linux 9.3 Repository which is of the version PCS 0.11.6 does not seem to install with Ruby Version greater than Ruby 3.0

Assuming something wrong with the RPM I attempted to the build my own PCS version and faced the same issue again,
I have Ruby 3.1.2 installed and I have tried this a couple of times!

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables ruby_CFLAGS
and ruby_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

Hi @ncsrikar,
ad 1) installation
It looks like you have enabled some ruby modules which has non-default ruby version. Check dnf module list. Pcs is built against default ruby version (3.0.* something).

ad 2) build pcs from sources
You doesn't have installed package ruby-devel. Install it and try again.

Hi @mirecheck,
I installed Ruby from the official Alma linux repository and this is the latest version they seem to have.

pcs claims support for above Ruby >=2.5....so I found it was odd not installing for Ruby 3.1...
I checked the libraries installed and there is libruby.so.3.1() and libruby.so.3.1.2() available in my system.

Hi @ncsrikar,
it is true that upstream pcs supports Ruby >= 2.5. The issue on Alma linux is that pcs bundles some rubygems which has extensions written in C language and they were compiled against ruby and ruby libraries of version 3.0.

You can try:

1. remove ruby-3.1 packages and then install pcs which should work
2. re-build your own pcs package against ruby-3.1
3. ask Alma linux support to provide pcs package built against ruby dependencies of desired version
