So, it requires at least GCC 8, while GCC 7.5.0 is the default in MarIuX. So, I source the GCC 11.1.0 profile, but have to do more I guess:

$ source /pkg/node-16.15.0-0/profile
$ npm --version
node: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by node)

Help from the RPATH experts much appreciated.

Or do I just adapt LD_LIBRARY_PATH in the profile like below?

$ export LD_LIBRARY_PATH=/pkg/gcc-11.1.0-0/lib64:/pkg/gcc-11.1.0-0/lib
$ npm --version
8.5.5

rpath is complicated. Even more so, as "man ld" is not working currently :-)

Maybe just put the LD_LIBRARY_PATH into the node profile. This only works for commands via wrapper not for someone doing /package/node-XXX/bin/blabla but you shouldn't been doing that anyway.

No, better ". /pkg/gcc-11.1.0-0/profile" into the profile of node.

No, better ". /pkg/gcc-11.1.0-0/profile" into the profile of node.

Unfortunately, that does not work with GCC packages: #193

To work around it, I am using LLVM/clang 13.0.1 package instead.

You could also fix the gcc package first. Win-Win. But this is fine, too.

I stayed with LLVM/clang 13.0.1, as that is from 12/2021 and newer than GCC 11.1.0 from 4/2021.
