bug#66537: configure: error: The Guile bindings of GnuTLS are missing

[Hiep Pham via Bug reports for GNU Guix]

Hi,

I'm on Fedora and started a shell with:

```
guix shell -D guix help2man git strace --pure
```

And then:

```
./bootstrap
./configure --localstatedir=/var
```

And it showed me this error:

```
[snip]
checking for guile-3.0 >= 3.0.3... yes
checking for guile-3.0... yes
checking if (gnutls) is available... no
configure: error: The Guile bindings of GnuTLS are missing; please 
install them.
```

I started the shell again with some dependencies but no luck :(

```
guix shell -D guix git strace guile-gnutls gnutls --pure
```

My current (guix describe):

```

Have you installed Guile 3.0 via Fedora’s package manager also?  Then
maybe configure finds Fedora’s Guile where Guile-GnuTLS is not
installed.  You could try using a container to confirm:

guix shell -C -D guix help2man git strace

Then try again:

./bootstrap
./configure --localstatedir=/var

When this works configure is probably finding the wrong Guile binary.
Alternatively look into the file config.status which is generated by
configure for a line like

S["GUILE"]="/path/to/guile"

This shows which Guile binary is found.

Running `guix shell -C -D guix help2man git strace --pure` in a 
container solved my problem! Thanks.

I followed this contributing guide [1] in the manual. It might be 
helpful to update the documentation to run the shell in an isolated 
container.

bug#66537: [PATCH] doc: Recommend building in ‘guix shell -CPW’.

[Ludovic Courtès]

This was prompted by <https://issues.guix.gnu.org/66537>, where someone
tried to build Guix within ‘guix shell --pure’ on a foreign distro and
found that ./configure would pick software from the host system.

Suggested by Hiep Pham <hiepph9@proton.me>.

I would not recommend that or adding also the option -N.  Else, the
development experience can be annoying.

For instance, “make check” will probably fail because some substitutes
are missing (see #67532 [1], e.g., tests/derivations.scm).

Moreover, one needs to go out the shell for submitting with “git
send-email” but then git:send-email is not necessary available in PATH.

As said, I disagree with this change pushed by
01361d46b8e0481ad56665d7a06c276b08f59c6d.

Could you revert?  Because as explained by…

…the option ’-CPW’ is not a solution.  Other said, it would require in
addition ’-N’.

To me, this recommendation of container is like a bazooka for chasing
the real bug: about why --pure does not clean all as expected.  Or why
“guile” is found elsewhere?

simon

Ludo’s answer from bug#67532 [1]:

I had come to forget about that because for the ‘guix’ package
(obviously built in a network-less environment), we “pre-seed” the store
with the 4 or 5 files needed to run the test suite.

So I propose:

…a bazooka for killing a fly.  For instance, in the two message of the
initial bug report, I do not see the output of the current
recommendation: run “guix shell --check”.

Yes, “guix shell” depends on the goodwill of the user’s shell but
recommending first --pure is an opportunity for improving --check and/or
--pure itself, IMHO.

Considering this reported instance of issue, it is not clear for me that
--check would not have reported the problem.  Or why --pure does not
correctly clean all the environment variables?  Or why ./configure set
something system wide?

For me, these questions are the bug.  And -CPWN is just a temporary
workaround avoiding the bug and not a fix.

Somehow, if the use of “-CPWN” instead of “--pure“ is not an idea that
user has when hitting a failure with “guix shell --pure”, yeah maybe it
could be helpful to recommend it in addition.  And not the contrary. :-)
