Compiler errors on Ubuntu 20.04

[hansbogert]

This seems to be related to #35 but I'm not well-versed enough in either snap or emacs to understand where this is going wrong:

Thanks for reporting this issue - can you post the output of snap info emacs? Also within emacs:

M-x describe-variable native-comp-driver-options (or similarly C-h v native-comp-driver-options).

I can't reproduce this myself locally on an up-to-date Ubuntu 20.04 install so any other details you can provide would be great.

M-x describe-variable native-comp-driver-options (or similarly C-h v native-comp-driver-options).

native-comp-driver-options is a variable defined in ‘comp.el’.

Its value is ("--sysroot=/snap/emacs/966/" "-B/snap/emacs/966/usr/lib/gcc/")

Options passed verbatim to the native compiler’s back-end driver. Note that not all options are meaningful; typically only the options affecting the assembler and linker are likely to be useful.

Passing these options is only available in libgccjit version 9 and above.

This variable was introduced, or its default value was changed, in version 28.1 of Emacs. You can customize this variable.

If this helps, it's a spacemacs instance.

Thanks - so that all looks normal - I wonder if this is specific to spacemacs... can you try and come up with a minimal recipe to reproduce the issue?

[hansbogert]

Can't reproduce anymore after removing ~/.spacemacs.env it held a couple of outdated environment variables. I never knew spacemacs created that on first start.

Hope this helps others.

Thanks, glad you were able to resolve it.
