Yep!
According to https://stackoverflow.com/questions/34879686/loading-gnu-ld-script-with-dlop... and https://sourceware.org/legacy-ml/libc-alpha/2011-07/msg00152.html
It would probably a good Idea to expose the contents of gnu/lib-names.h in case we are on a GNU-Libc system (like RHEL/Debian based as opposed to eg, musl-based systems such as Arch, or any other Unix for that matter).
Should we hence put a category of well-known system library names into primitives with default names as fallback?
such as
UnixFFI class>>libcName <primitive: 'primitiveLibcName' module: 'SqueakFFI'> "or something" ^ 'libc.so' "unixy default"
(I'm making thinks up as I go…)
-t
I then checked in /lib64/ and found
/lib64/libc.so.6
I put that in the preferences and all is good.
Thank you for your help!

Thanks for the advice.
I did as you suggested.
Runing squeak.sh I just noticed the following in the xterm from which I launced it:

I removed the leading '/' due to the dlopen: // message, but same result different output.

Hmm... you might want to try a fully qualified path? At least that's required in Ubuntu ... if you have an idea on how to improve CStandardLibrary class >> #guessModuleName, feel free to share it here. :-)
Do other libraries load through FFI?

Hi folks
I downloaded the latest Squeak from trunk (looking good btw, and very fast)
After installation and adding the options in the wizard, I am getting:
C standard library not available. Please check module name in preferences.
Error: External module not found
I am running Slackware Linux 64. Slackware has an oddity about it in that the core libraries are in /lib64 instead of /lib in case you suspect its a path issue.

Hi Tobias --
Should we hence put a category of well-known system library names into primitives with default names as fallback?
Hmm... can this info already be retrieved from other VM parameters already accessible? See CStandardLibrary class >> #guessModuleName for the current "magic". It uses the following VM attributes:
1001 #platformName 1002 #osVersion 1003 #platformSubtype
