[Gimp-developer] Trouble compiling 2.99

[Ofnuts <ofnuts gmx com>]

I'm trying to compile 2.99. It used to work, but my last successful
attempt was in June 2020.

Compiling on Ubuntu 19.10 but I upgraded meson and pango to required
versions.

When I use the meson build:


meson _build --prefix=${GIMP_PREFIX} --buildtype=release
-Djavascript=always -Dlua=always -Dpython=always

cd _build && ninja

It stops with:

[450/1967] Generating gimp-3.0.vapi with a custom command

Am I missing something?
