Thanks for the reproduction steps.
To debug: hack meson to get it to disgorge the pickled command it's executing,
then you can run the failing g-ir-scanner command line while poking at things in
/usr/lib/gobject-introspection/giscanner/
This actually looks like a bug in 'g-ir-scanner --no-libtool' (which obviously
isn't usually exercised by an autotools build), failing in this particular case.
It looks to match the following list of regexes:
([^\s]*cyg*harfbuzz[^A-Za-z0-9_][^\s\(\)]*)
([^\s]*cyg*harfbuzz\-gobject[^A-Za-z0-9_][^\s\(\)]*)

Unfortunately, the first regex matches the cygharfbuzz-gobject line, leaving the
second regex unmatched.
We have to allow a '-' to appear after the library name, as that introduces a
soversion, so I worked around this by patching

Jon,
No one has suggested a better fix, so I think we should get your fix into the
distro. It's not urgent, because harfbuzz still supports both autotools and
meson, but they're encouraging packagers to move toward meson.
How do you think we should proceed? Are you interested in adopting
gobject-introspection? Alternatively, one of us could do a non-maintainer

Thanks, Jon! Just as your mail came in, I was staring at the regex for
harfbuzz-gobject in shlibs.py, trying to understand why it wasn't
matched. It never occurred to me that the cygharfbuzz-gobject-0.dll
line in the ldd output was being used to match the regex for harfbuzz
rather than the one for harfbuzz-gobject. What a mess.
Yeah, I went around in circles on that a few times myself :)

If I remove all the commas but leave the single quotes, the command fails with the same error message as before: cp: target 'docs/index.html.tmp' is not a directory If I also remove the single quotes, the command succeeds. I think the problem is the quotes around the double ampersands, so they are treated as arguments to the cp command instead of being interpreted by the shell executing the command. So, yeah, this is a meson bug, which I will work on (if this command ends up in the build.ninja, it's executed by ninja with 'sh -c', but if it ends up in a pickle, it's executed by meson with execve()) Yes, that does seem like a meson bug. But is it also a babl bug to some extent? When babl puts '&&' in a command argument, it's assuming that the command will be executed by 'sh -c'. I have very little experience with meson. Have you ever seen this issue in other projects that use meson? I just noticed this, at https://mesonbuild.com/Custom-build-targets.html : Meson only permits you to specify one command to run. This is by design as writing shell pipelines into build definition files leads to code that is very hard to maintain. If your compilation requires multiple steps you need to write a wrapper script that does all the necessary work. We're not talking about a shell pipeline here, but it's similar. So I'm thinking this really is a babl bug. Yeah. Ideally meson would stop people from writing custom targets which use shell operators. Unfortunately, it doesn't and there are probably many other existing instances of this usage. Additionally, meson is perhaps a bit schizophrenic on this topic and (I think) actually has code to make sure this works as expected when the command ends up being put directly into build.ninja (which is what will usually happen on linux etc.) Regardless of whose bug it is, I've got a simple but ugly workaround (attached), now that you've explained to me what's going on. Good stuff.

I'm having trouble with babl, which is needed for gegl0.4, which
is needed for gimp. The problem involves gobject-introspection.
If I disable introspection, the build works fine. This would be
OK, since babl has been built without introspection for several
years. But then the gegl0.4 build complains about the missing babl

Yeah, this looks extremely plausible, there seem to be no GObject
derived types in babl's interface.
It might be possible to work around this by patching in a dummy GObject
derived type which does nothing.
I'll have to see if I can find my notes about how I debugged this before.
By the way, in case you're wondering why I disabled the building of

don't know if this is related to the introspection failure. The

By the way, in case you're wondering why I disabled the building of docs, it's
because I was getting a build failure there too. I don't know if this is
related to the introspection failure. The failing command there is
/usr/bin/meson --internal exe --unpickle

cp: target 'docs/index.html.tmp' is not a directory
I don't know why it's not showing me the actual cp command that fails.
I believe it's is an infelicity in meson that it doesn't echo the actual failing
command here.
Noted here: https://github.com/mesonbuild/meson/pull/3716#issuecomment-395746838
The corresponding information in docs/meson.build is
Reference_html = custom_target('Reference.html',
input : [
'Reference-static.html',
'toc',
index_html_tmp,
],
output: [ 'Reference.html', ],

'&&', xml_insert, '@OUTPUT@', 'TOC', '@INPUT1@',
'&&', xml_insert, '@OUTPUT@', 'BablBase', '@INPUT2@',

)
There are several such custom targets in the file, and for all except this
one, I see the actual cp command in the log. This is the only one for which
meson generates a 'meson --unpickle' command instead of a cp command.
Yeah, I wasn't expecting it to use this method of executing the command line
(storing it in a pickle and then using a python wrapper to execute it) to be
used except on Windows, so I'll have to take a more detailed look at why that's
happening.
