Hi,

'./pre-inst-env guix-build gobject-introspection' fails with the
following error:

  GICOMP gir/cairo-1.0.gir
Traceback (most recent call last):

The problem isn't version-specific.  I tested several versions.  I also
tried to remove all Cairo-related things from 'Makefile.in', but it
didn't help.  My guess is that our GLib causes the problem, but I'm not
sure.

Here's a snippet from Nixpkgs:

   # Tests depend on cairo, which is undesirable (it pulls in lots of
   # other dependencies).
   configureFlags = "--disable-tests";

AFAICT, this flag is useless because the tests are disabled by
default.

Isn’t there by any chance a /bin/sh behind this?

You can check by running that in ‘strace -f’, from the failed build tree.

I haven't found anything strange in the output.  Could you help me to
investigate?

I've attached the recipe; it's possible that some phases aren't needed.

Looking at subprocess.py above, I see this:

The solution is to patch Python to refer to our ‘sh’ instead of /bin/sh
(as is done for Guile’s ice-9/popen.scm).

Can you do that?

TIA,
Ludo’.

I changed 'arguments', but 'gobject-introspection' failed with the same
error.

python.scm:

Good.  You can already commit that one (but please make it
(string-append bash "/bin/sh") rather.)

Are you looking at the subprocess.py that’s actually mentioned in the
gobject-introspection backtrace?

If yes, then it likely means that it’s the caller–i.e., some .py file in
gobject-introspection–that’s passing /bin/sh somewhere.  Can you check
the files mentioned in the backtrace?

HTH,
Ludo’.

I found more and added them to 'python.scm'.

There are other files that use faulty shells, but I'm not sure that they
are really needed (e.g., platform-specific ones).  Could you check them
using 'grep -r "/bin/sh" .'?

Yes.

Those are fine (I guess).  The only file I found is 'm4/libtool.m4'.  I
added it, but 'build' failed again.

I'm attaching both recipes.  Please have a look.

libraries (using GObject) and language bindings.  The C library can be
scanned at compile time and generate a metadata file, in addition to the
actual native C library.  Then at runtime, language bindings can read
this metadata and automatically provide bindings to call into the C
library.")

is used in a wide variety of application domains.  Some of its key
distinguishing features include: clear, readable syntax; strong
introspection capabilities; intuitive object orientation; natural
expression of procedural code; full modularity, supporting hierarchical
packages; exception-based error handling; and very high level dynamic
data types.")
