    branch: master
    commit: e7ddeacc0c122564990f3a5ff6b45e3fc7dd1106

The gcc-toolchain package does not provide cc in PATH, as might be expected:

$ guix shell --pure --container gcc-toolchain
[env]$ cc --version
sh: cc: command not found
[env]$ c++ --version
c++ (GCC) 15.1.0

I'm sorry if my response is not very helpful. I've came across this issue as well while learning about GUIX, in my notes I saved this link from a report made 8 years ago:

https://issues.guix.gnu.org/28629

However, if using guix shell I think you can add this to the top of your manifest.scm files in case you are working with projects of your own:

(setenv "cc" (getenv "gcc")) ;; adapt to your needs

I found placing this before any module/use-module definitions is enough for LD_LIBRARY_PATH issues that arise with other programs out there.

If you don't like that approach I would suggest looking the SRFI-98 section in the Guile Scheme manual if you want a "cleaner" approach. Happy hacking!

This is intended behaviour. see also

(BTW, I hope @mhw can provide a link to the discussion about not adding cc symlink for gcc-toolchain

Here are some of the early discussions on this topic that I found:
