sorry for spamming but I’ve just experimented a little bit and I notice that every time I select a filter or LUT from the list, the “Update filters” button becomes active as well. Where does G’MIC get its filters from? Are they stored locally or does he go to the internet every time?
I have now tried all LUTs and except (Expired) all Instant Consumer LUTs work. All Instant Pro LUTs work too. For all others I get timeout.
Notice: I always update filters before I start to work with G’MIC!
I really don’t know for the moment… let’s wait until @David_Tschumperle has a chance to read this messages, I hope he can shed some light!
I have tried again but for me no lut is working (only seems to work if you don’t choose the preset and leave it to none).
And also grain.
Seems that it is impossible to download preset, maybe to a read only tmp dir for g’mic downloads? Or maybe to g’mic now a bit old version?
I attach a screenshot.
I don’t know if it will make a difference, but the current version is 2.4.5. You have a pre-release version of 2.4.3
Yes but pre 2.4.3 is integrated in the Appimage, i think it isn’t feasible to upgrade without rebuilding the appimage.
@ggc @Bilbo let me have a look later today. The GMIC version in the AppImage should be automatically updated to the latest available… which version of the AppImage are you using?
i am using GIMP_AppImage-release-2.10.8-withplugins-x86_64.AppImage from https://github.com/aferrero2707/gimp-appimage/releases
Could you try the very latest one?
https://github.com/aferrero2707/gimp-appimage/releases/download/continuous/GIMP_AppImage-git-2.10.9-withplugins-20190228-x86_64.AppImage
Same problem (i’m using ubuntu mate 18.04.2 now). Seems also here the Gimp icon is missing. Thank you.
.
In my case, when I hit the “OK” button to apply the filter (even if the preview has timed out), I get the following error:
*** Error in ./fx_simulate_film/_fx_cluts/*if/(...)/*if/*repeat/*if/*local/ *** Unreachable network file 'https://gmic.eu/gmic_cluts.gmz'.
I suspect the two problems are related. I will try to figure out why network access does not work…
yes i get this too if pressing ok
I’m on it…
Maybe some things, if it may help :
G’MIC uses calls to the library libcurl to retrieve files from the G’MIC domain https://gmic.eu , as a few filters require external data to be loaded (loaded files go to the G’MIC resources folder, which is often $HOME/.config/gmic ).
Thanks @David_Tschumperle. After some more investigations, it turn out that the error returned by libcurl is CURLE_SSL_CACERT_BADFILE. That is, the CA certificate is not accessible for some reasons… I have to see if that is a problem of environment variables.
@ggc @s7habo @Bilbo @David_Tschumperle
After more investigations, it turn out that there is a mismatch between the LibCURL version that is bundled in the AppImage (and used by G’MIC to download the CLUTs) and the CA certificates that are available in systems like Ubuntu 18.04
The more reliable solution I have found is to disable the LibCURL support in G’MIC/CImg, and let the code fall back to external CURL/WGET commands for downloading network files. Either curl or wget should normally be present on all Linux systems, so that should not be a big limitation.
@David_Tschumperle is that OK for you?
I have prepared a new AppImage package with this fix included. Could you please test it and see if the film emulations now work properly for you as well?
Thanks!
Thanks for the investigation !
Thank you it works!
@Marcello_C @ggc the missing icon problem should be finally fixed in the latest packages from today. Could you please check & confirm?
