Hello.
Basically I followed this guide to install GIMP 2.7 from git in /opt folder:
http://www.gimpusers.com/tutorials/comp ... for-ubuntu

If I use the G'MIC binaries for GIMP 2.6, in GIMP 2.7 I get the message:



Then I try to compile G'MIC 1.5.0.6 starting with:


Ends all good. But when I trying "make" or "make gimp" from /src the process takes too long and basically get stuck and the process "cc1plus" uses 50% CPU. "make" stuck on (sorry, konsole spanish output):


System: Kubuntu 11.10 Oneiric 64bits

Thanks for your help. Sorry for my English (my language is Spanish)

I remember that to compile gmic you must skip configure and just make
But is strange that doesn't work for you the compiled version, it should just give a warning not a critical error.

If not more helpful reply come from here ask on http://www.flickr.com/groups/gmic/discuss/ anyway i almost sure you should just skip configure

I do not know, I got that message and searching I found this:

Ok, but I need to install it into /opt, so that does not interfere with GIMP 2.6 installation.
Anyway I tried skipping configure, entering to /src and run "make gimp" and the same is happening to the point of almost hang my system.
I thought it could be something related to the compiler, but before I was able to compile and install "babl", "gegl" and "gimp" successfully.


Ok, thanks!

Hi YAFU,
I wrote a howto install gimp-2.7 from git sources if you're interested.
viewtopic.php?f=10&t=1261

Anyway this is wrong:

It will try to install gmic there but it should go into /opt/gimp-2.7/lib/gimp/2.0/plugins.

To make life easier on yourself I suggest you install "mc".
Use it in a terminal and you can easily browse your system and a lot more.

Thanks Gerard!, practically that is what I had made to install from git. The difference is that you specify the paths and the guide I used "export" paths before compilation. I must say that before compiling G'MIC I have also exported these paths.

I assumed that the part of "/lib/gimp/2.0/plug-ins/" was not necessary and build instructions are to be installed there. Anyway, I've tried with "cofigure" in many ways and without "configure" and always gets stuck in "make". I start to think it may be something related with compiler version of Ubuntu, but it is weird because I had no problem to compile gimp.
By the way, have you been able to use plugins in GIMP 2.7.x installed in /opt?

To compile G'MIC, just go to 'gmic/src' and type 'make gimp'. It will skip the compilation of the command live version which is indeed very CPU consuming.

@ Ronounours,
I have compiled gmic with various prefixes w/o Gimp-2.7 being able to use it.
I always get an executable ok.
But Gimp always complains about it using an obsolete plugin protocol.
I have no idea what the correct protocol is or how to modify the commands.
Any help very welcome.
Gerard.

@Gerard, I'm afraid the GIMP team has modified some important things in the plug-in API, and probably the G'MIC plug-in won't be working for the latest 2.7 releases (and probably not for 2.8 too). I need to check this assertion, but at least, what you describe seems to proove that the deprecation of the plug-in API is in process.

I always knew this time will come one day. I hope I can find a quick fix, otherwise the G'MIC plug-in will be stick with the 2.6 version. If you have more informations on this error, let me know.
Do other plug-ins get the same error ?

Hi Ronounours,
Yes plenty of scripts and plugins fail with similar error messages.
Xsane as scanner plugin for instance.
When I install gutenprint the normal Gentoo way it installs a plugin for Gimp-2.6.
When I copy this to the Gimp-2.7 plugin directory it fails.
I got the gutenprint plugin working by compiling the source with prefix=/opt and it then installs it in /opt/lib/gimp/2.0/plugins.
The gutenprint source I got from /usr/portage/distfiles where Gentoo keeps all the sourcefiles you install.
When I compare the sizes I notice that for 2.6 it's 36152 bytes and for 2.7 it's 29430 bytes in size.
Yet they both have the same gui and both work ok.
Since these are binaries I have no means to find out what the difference is.
Thanks for your efforts and if I could do anything else for you just holler.
Gerard.

Start gimp from the terminal with " gimp --verbose" is no sufficient to see what the problem ?

It seems improbable critical changes in the API coming just now, when the priority is speed up the release

Here's part of the result of /opt/bin/gimp27 in an xterminal:

I have no idea what process 16412 is.

Hi David,

Just compiled g'mic 1.5.0.6 for gimp-2.7.4 (November 7th nightly-tarball). So, it's OK so far. I am planning to make it available soon.

Thanks,
Partha

I created a separate partition and installed Gentoo Linux on it using the same configuration as in my regular install.
I did not install all the software that I have on my regular install but what I left out is nothing graphic.
I compiled Gimp from git using --prefix=/usr instead of /opt.
Now the G'mic plugin works fine!
I have no idea why it works ok in /usr and not in /opt.
Anyway when 2.8 is ready I want to install it in /usr on my regular install to replace 2.6 and G'mic will work.
Gerard.

Thanks Gerard for taking your time to do that experiment.
It would be interesting to know why the plugins do not work if GIMP installation is in /opt. I will try to find out.

Thanks Gerard, that was then a false alarm, at least for now

You're both quite welcome.
I can't code but having used Gentoo for 8 years one gets a lot of experience in compiling from source.
Gerard.

Edit: I added a warning to the howto I wrote:
