gimp @2.8.16: +gmic variant is not compatible with +quartz

[kurn@…]

Yosemite 10.10.5 - Xcode 7.2.1 (7C1002) - I asked for +gmic variant but gmic filters did not appear in the Filters menu. Here is terminal output:

First, please verify which versions of gimp, gimp2 and gmic are installed. What is the output from the following commands?

$ port installed gimp gimp2 gmic
$ which gimp

Replying to devans@…:

First, please verify which versions of gimp, gimp2 and gmic are installed. What is the output from the following commands?

$ port installed gimp gimp2 gmic
$ which gimp

Your request, plus a few more:

bash Godzilla.local 500 ~ $ port installed gimp gimp2 gmic
The following ports are currently installed:
  gimp @2.8.16_0+gmic+quartz (active)
  gimp2 @2.8.16_3+help_browser+python27+quartz (active)
  gmic @1.5.0.8_6 (active)

Since I use the Finder to launch, I can choose which of the 2 in the Applications directory to start. I didn't realize there was a third. Also, strange that the one in the App is newer than the one in MacPorts and the one in /opt is newer still.

Hopefully, you can tell me where MacPorts installs and how to connect to it.

Sorry for not getting back to you on this. I had it in my mind that the issue was resolved but I see it is not. So thanks for the nudge.

It appears that you have two or maybe parts of three different installations of gimp on your machine only one of which is the MacPorts version and there may be some interaction between them.

As your which command shows, port gimp2 installs the basic GIMP application itself as

/opt/local/bin/gimp

You can see where it is installed by using the command

$ port contents gimp2

The corresponding plugins directory is

/opt/local/lib/gimp/2.0/plug-ins/

Using a similar command you can see that gmic installs its plugin as

/opt/local/lib/gimp/2.0/plug-ins/gmic_gimp

This is correct and you should be able launch the GIMP app from the command line as

$ gimp

If all this is correct, then GIMP should start up and you will see the gmic plugin under the Filters menu.

Unfortunately, it appears that gmic is always compiled using gtk2 +x11 and so fails to load when using it with a clean +quartz build of gimp2

$ gimp

(gimp:9174): LibGimpBase-WARNING **: gimp: gimp_wire_read(): error

This is an issue with the gmic port itself. Appears it needs a +quartz variant to properly configure a build using gtk2 +quartz. I'm copying the owner of that port and will file a ticket against gmic as soon as I finish a bit more testing.

Concerning the app bundle, it is installed by port gimp-app and is the one found at

/Applications/MacPorts/GIMP.app

It is just a script so start up /opt/local/bin/gimp in a Mac friendly way. You should see that

/Applications/MacPorts/GIMP.app/Contents/Resources/bin

is just a link to

/opt/local/bin

Finally, on startup, GIMP will create some configuration files in

~/Library/Application Support/GIMP/2.8

If you remove these, GIMP will recreate them with default values on the next startup.

Beyond these paths and directories, anything that looks like GIMP is not the MacPorts version and I would recommend removing them to avoid confusion or any adverse interactions with MacPorts.

The port gimp is just a "meta port", one that just installs a list of other ports, namely, those above and some extra filters, etc.

Hope this clarifies the issue. Let me know if you have any questions.

As I mentioned above, other than understanding which GIMP is which, the solution to this problem is to fix the gmic port to build using gtk2 +quartz in a +quartz environment.

Working on this.

[dbevans (David B. Evans)]

Examination of port gmic shows that it is intended build with X11 only. Until this is changed variants +quartz and +gmic conflict with each other and need to be mutually exclusion. For now, I've updated gimp in r146459 to allow only one or the other.

If you really need to use gmic with gimp then you should build with X11 not +quartz.
