'guix-build' returns 'unknown package', Bison's testsuite fails

'guix-build' returns 'unknown package', Bison's testsuite fails

Hi,

I'm trying to package 'gobject-introspection', but I'm facing some
problems:

  1. 'guix-build' doesn't work for new packages; it returns
     "<package>: unknown package."  I'm using the '-e' option as a
     workaround, but it's not very convenient.

     For instance, if I copy the recipe for 'sed' to 'newsed.scm', then
     replace 'sed' with 'newsed' in that file, and try to build it via
     'guix-build newsed', it will return the mentioned error message.
     However, it will work if I use the '-e' option.  Also, I won't get
     any errors if I try to import it in the REPL.

  2. Bison's testsuite fails and I'm not able to fix it.  So I'd like to
     disable it because I want to test 'gobject-introspection'.  Why
     doesn't '(arguments `(#:tests? #f))' disable the testsuite?

These issues may seem unrelated, but there is a similarity: My changes
have no effect.  I've just replaced 'gnu/packages/bison.scm' with an
empty file, but 'guix-build bison' doesn't raise any errors.  Is it
related?

That has happened to me before when I forgot to execute "make install" or 
to add a file to Makefile.am.

Also, after deleting a file, it is not deleted from $PREFIX/share/...; in 
this way, it has happened to me that I had two versions of a package, one 
from a deleted/renamed file, one from the file with the new name; and the 
wrong one was built...

‘guix-build’ searches all modules under gnu/packages; in those modules,
it searches all the public variables that match ‘package?’, and finally
compares against their ‘name’ field.

Could it be that your package is not in a public variable?

That’s expected: what matters it the ‘name’ field of the ‘<package>’
instance, not the name of the file that defines it.

Can you provide more details?  It appears to build for me as
/nix/store/2kdr905aj5kkm0mrwjqxsgv6zvmh2y0j-bison-2.6.1 (x86_64-linux).

Actually, there’s an evil bug.  ‘guix-build’ & co. do this:

  GUILE_LOAD_COMPILED_PATH="@guilemoduledir@:$GUILE_LOAD_COMPILED_PATH"
  export GUILE_LOAD_COMPILED_PATH

So if you’ve run ‘make install’ before, the installed modules will
prevail over the non-installed ones.

I’ll see how to fix it.  In the meantime, you can, ahem, run
‘make uninstall’ or ‘make install’...

Thanks,
Ludo’.

I'm not sure, but I think that 'make uninstall' solved the problem.

I've attached the part of 'testsuite.log'.

Hi,

Can you check in the build log of 6kj7f8kz3h5fizir8l7nrxgras2ns3ww-m4-1.4.16
what the line “checking which shell to use for syscmd” says?  (Remember
that build logs are kept in /nix/var/log/nix/drvs or similar, depending
on your localstatedir.  Make sure the value passed to --prefix in that
log matches the one above.)

Here it reads this:

  checking which shell to use for syscmd... /nix/store/ryk1ywzz31kp4biclxq3yq6hpjycalyy-bash-4.2/bin/sh

If it chose /bin/sh, then it means that you built M4 out of the chroot
(or with /bin in the chroot), but now you’re trying to use it within a
chroot.

There were no logs.  So I ran 'nix-store --delete 6*w-m4-1.4.16', then
reinstalled it, and 'bison' succeeded.
