First Time Gimp Build

[Ofnuts]

Sorry, got lost in all your posts

[pixelmixer (mark sweeney)]

I use the same variables as the build for 2.99.15, see top of page.
I cloned the branch as you suggested, had to do it slightly differently though.

$ git clone --depth 1 -b "GIMP_2_99_14" https://gitlab.gnome.org/GNOME/gimp GIMP_2_99_14

Then:

# copied and pasted into a terminal
cd $GIMP_PREFIX/build/GIMP_2_99_14
meson _build \
     --prefix=${GIMP_PREFIX} \
     --buildtype=release \
     -Dpython=true

-Dpython has to be a boolean this time.

Same result:

meson-log

~/Code/gimp-source/build/gimp/meson.build

I suspect this line in GIMP master lets it build.
babl = dependency('babl-0.1', version: '>='+babl_minver, required: false)

…required: false…

Same line in 2.99.14
~/Code/gimp-source/build/GIMP_2_99_14/meson.build
babl = dependency('babl', version: '>='+babl_minver)

no false!

Can build if changed to match.

[jboerema (Jacob Boerema)]

There were some changes after 2.99.14 regarding finding the babl package. I think the relevant part is using babl-0.1 instead of babl.
