gimp2: Error: GIMP configuration failed

[squiggledid]

Port gimp2 fails during configuration on MacOS 10.14.6 with the error message:

--->  Configuring gimp2
Error: Failed to configure gimp2: consult /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_graphics_gimp2/gimp2/work/gimp-2.10.28/config.log
Error: Failed to configure gimp2: configure failure: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_graphics_gimp2/gimp2/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets if you believe there
is a bug.
Error: Processing of port gimp2 failed

I tried cleaning and trying again. Same result. I uninstalled and then tried installing again. Same result. I will attach the main.log and the config.log.

The main.log says the problem is:

:info:configure Error: GIMP configuration failed.
:info:configure   - PyGTK 2.10.4 or newer
:info:configure       *** Please install it, or skip building the python scripting extension by
:info:configure       *** passing --disable-python to configure (but then you will not be able
:info:configure       *** to use scripts for GIMP that are written in Python).
:info:configure See the file 'INSTALL' for more help.

The config.log explains further:

configure:34397: checking for pygtk-2.0 >= 2.10.4
configure:34404: $PKG_CONFIG --exists --print-errors "pygtk-2.0 >= 2.10.4"

configure:34421: $PKG_CONFIG --exists --print-errors "pygtk-2.0 >= 2.10.4"

configure:34438: result: no
Variable 'PYTHON_EXEC_PREFIX' not defined in '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/pkgconfig/pygtk-2.0.pc'

What happens if you run:

PKG_CONFIG_PATH=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/pkgconfig pkg-config --exists --print-errors "pygtk-2.0 >= 2.10.4"; echo $?

On my system the result is

0

meaning no error, but I wonder if you get a different result. If so, maybe try forcibly uninstalling and then reinstalling py27-pygtk.

I also noted these errors in the main.log which probably also indicate something wrong:

:info:configure checking for matting engine Levin... GEGL-Message: 10:04:05.538: Module '/opt/local/lib/gegl-0.4/ff-save.dylib' load error: dlopen(/opt/local/lib/gegl-0.4/ff-save.dylib, 10): Library not loaded: @rpath/libgio-2.0.0.dylib

:info:configure   Referenced from: /opt/local/lib/libavcodec.58.dylib
:info:configure   Reason: image not found

(The use of @rpath seems wrong to me.)

I tried what you suggested, and got this:

pkg-config --exists --print-errors "pygtk-2.0 >= 2.10.4"; echo $?
Package pygtk-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `pygtk-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'pygtk-2.0' found
1

I then uninstalled and reinstalled py27-pygtk. I get the same result:

pkg-config --exists --print-errors "pygtk-2.0 >= 2.10.4"; echo $?
Package pygtk-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `pygtk-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'pygtk-2.0' found
1

Yet it is indeed installed:

port installed | grep pygtk
  py27-pygtk @2.24.0_4+x11 (active)

So, has something broken broken the pkg-config search path? it is:

echo $PKG_CONFIG_PATH
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/pkgconfig

I don't know what it should be.

Both ports were updated late yesterday. Please rerun sudo port selfupdate, and try the install again.

[mascguy (Christopher Nielsen)]

Oh, be sure to re-run sudo port clean --all gimp2 first as well, before retrying the install.

[squiggledid]

I'd already uninstalled and cleaned all my gimp2 versions.

I restarted the process as soon as I got your first message. The new update resulted in py27-pygtk @2.24.0_5+x11 being installed. gimp2 (gimp2-2.10.28_0+python27.darwin_18.x86_64) then configured successfully, and started building. It is now staging into destroot.

It would seem that the new gimp2 port was released before the new version of the py27-pygtk port on which it depended. This is not good.

[mascguy (Christopher Nielsen)]

Great, glad it's working!

As for py27-pygtk: Despite a lot of exhaustive testing ahead of time, this issue was somehow missed. But thanks to two of my fellow members - who not only identified the issue, but also provided the fix - we caught it quickly. You just happened to be bitten by it, before the fix was committed.

The price of doing updates first thing in the morning in Australia, I guess :)
