I would like to adopt gimp and related packages. At the moment 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 introspection files, so I would have to
disable introspection there too, which hasn't been done in the past.
So my preference is to figure out what the problem is and get the babl build
working with introspection. I'm attaching my cygport file and patch.
Here's the failing command...

ERROR: can't resolve libraries to shared libraries: babl-0.1
I don't understand the error message, because the command line contains
-L/tmp/cygbabl/babl-0.1.74-1.x86_64/src/babl-0.1.74/x86_64-pc-cygwin/babl
and that directory contains libbabl-0.1.dll.a and cygbabl-0.1-0.dll. I even
tried adding that directory to my PATH to make sure the right cygbabl-0.1-0.dll
would be found, but that didn't help.
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
/tmp/cygbabl/babl-0.1.74-2.x86_64/src/babl-0.1.74/x86_64-pc-cygwin/meson-private/meson_exe_env_7bf39b99114d34540b83d26a5d8f097e05882836.dat
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. 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', ],
command: [
env_bin,
'cp', '@INPUT0@', '@OUTPUT@',
'&&', xml_insert, '@OUTPUT@', 'TOC', '@INPUT1@',
'&&', xml_insert, '@OUTPUT@', 'BablBase', '@INPUT2@',
],
build_by_default: true,
)
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.
