I noticed when compiling a fresh instance of G’MIC cli in a proot-distro Ubuntu terminal that the APT manager did not have libgimp2.0-dev in it’s repos, but supposedly this is a prerequisite for compiling gmic according to the gmic.eu/download page.
I compiled with libgimp-3.0-dev instead, and everything seems fine so far. Note the extra hyphen in the name too…
Sometime in the future, probably. I compile for Ubuntu 24.04 / Mint 21 using the ubuntu Gimp 3 PPA installation. Missing was libgexiv2.dev (+dependencies)
Otherwise compiles for Gimp 3 ok.
