problem with gnutls in my local emacs build.

[joakim]

Hello,

I have a problem with gnutls in my local emacs build, on Fedora 34.

I get this error:

emacs -Q

(package-refresh-contents)

  
Debugger entered--Lisp error: (gnutls-error #<process elpa.gnu.org> -402)
  signal(gnutls-error (#<process elpa.gnu.org> -402))

I build from master from time to time, and my previous build works fine.
There is a difference in gnutls versions though:
  
working emacs:
libgnutls-version is a variable defined in ‘C source code’.

Its value is 30615


Broken emacs:
libgnutls-version is a variable defined in ‘src/gnutls.c’.

Its value is 30702

So I guess maybe something happened in the Fedora gnutls packages?

So I was thinking I should try to use a local gnutls build, so I can
tweak the config parameters to suit emacs. I would like this gnutls
build to be only know by emacs, and not the entire machine.

Is there some way to do this, other than building the pieces I want in
a container or something?

Thanks
