gimp plugins - Lce sometimes missing

(Ken Moffat) #1

[ Lce : Local contrast enhancement, abbreviated to fit in the editing window ]

I’ve been using G’MIC gimp plugins for a few months now, and the one plugin I almost-always use is Local contrast enhancement (I take three variants of the raw image at different EV adjustments and merge them - that generally makes things soft, sometimes so soft that it’s hard to see the detail). I build everything from source, and I build fresh systems every few months.

Until a few hours ago I’ve been compiling the gimp_gtk plugins, but after looking at Arch linux I finally found out how to build the qt version (download extra tarball, sed the .pro file, yadda, yadda).

Until yesterday I had thought all was fine - then I went back to the current build on my gimp-2.8 machine (2.0.2) and realised the Local contrast enhancement plugin was not in the menu - yet the same version on two gimp-2.9 machines was fine.

So, I’ve now built the 2.0.3 gimp_qt plugins on one of those 2.9 machines - and again the Local contrast enhancement plugin is not on the menu.

Any ideas, please ?


It should compile OK. This in Kubuntu 16.04 with Gimp 2.9.7 packages from the otto-meier/gimp-edge ppa

last compile was 2 weeks ago, and that had LCE. A brand new compile, just before writing this. It is 2.0.4_pre1709087

The start of the output is

Obviously lots of output after that final ‘make’ but no warnings, nothing strange that I can recognise. Do you get anything like that?

In Gimp 2.9.7

I don’t download via git because I’ve already downloaded gmic-qt-2.0.0 and renamed it to gmic-qt (and then sedded its project file so that it doesn’t fail iommediately (-Ofast implies -ffast-match for at least gcc-7.2).

Apart from the many gcc warnings (gcc-7) I cannot see any errors.

I’ve also compared the logs from my earlier builds of 2.0.2 gmic_gtk (for 2.9 it was ok, for 2.8 it too missed Lce) and nothing different shows up between them.

I eventually found the place to query this (github) - it turns out that local contrast enhancement is defined only in the update file, which usualyy gets downlaoded on first use of the particular version - I did not realise that (there are more than 100 filters in that category by the look of it) - I had a message about failing to connect on at least one occasion, but I hadthought that was only to tell me about new major/minor versions (I had those messages when I was using 1.7 and 2.0 came out).

Possibly I picked a bad time for my first use (overnight, maybe server was doing its housekeeping). Running the update manually (button at the bottom of hte g’mic plugin screen) solved it.
