bug#57436: Running ./configure from `guix shell -D guix --pure` errors

[Katherine Cox-Buday]

It gives me this error: configure: error: C++ compiler 'g++' does not
support the C++11 standard

I have to run `guix shell -D guix gcc-toolchain@12.1.0 --pure` to get
./configure to work.

Since `guix shell -D` includes the development packages for Guix,
maybe the package needs updating?

I'm pretty sure GCC 10 ought to support C++11.  There's probably some
other issue with your GCC, you might want to try `guix build --repair'.

Maybe ./configure somehow picks up an old g++ from outside the "guix 
shell" environment.

To avoid this, you can do `guix shell --pure -D guix'.

Don't forget to add --localstatedir=/var to ./configure, especially if 
you hack on the daemon -- otherwise if you start the modified daemon 
from your git checkout, the state will go out of sync.

Greetings,
Maxime

Thanks, Maxime!

Does the location of the `--pure` flag matter? I.e. I was running

`guix shell -D guix --pure` (suggested by the manual)

and you're suggesting

`guix shell --pure -D guix'

I would expect it not to matter.

Greetings,
Maxime.

This turned out to be the issue. I discovered my shell startup files were
mis-configured by running `guix shell --pure --check -D guix`. This is
definitely a user error, and my fault, but maybe we should update the manual
to include the `--check` flag?

Well, “guix shell” should hint a ’--check’ the first time you run it.
And is the explanation about ’--check’ (section Invoking guix shell) not
clear?

Do you mean update the «Building from Git» section?

Yes this is what I mean.
