Where do you have libmypaint-2.0.pc installed and what is your ${PKG_CONFIG_PATH} set to, if any?

[aoloe]

i have installed libmypaint in ~/bin/libmypaint ... what should be in PKG_CONFIG_PATH?

[aoloe]

ok, found:

export PKG_CONFIG_PATH=~/bin/libmypaint/lib/pkgconfig/

[hartwork]

Looks good. Does it work?

I am getting the same error, when I run scons as indicated here: https://github.com/mypaint/mypaint/blob/v1.2.x/README_LINUX.md

I have installed libmypaint in /usr/local/lib/
and I have exported pkg_config_path: export PKG_CONFIG_PATH=/usr/local/lib//pkgconfig/
But I am still getting the same error.

[briend]

@UmarSpa are you building from master branch? Scons is no longer supported

[aoloe]

i could compile mypaint with that change.

but, at the end, when running the resulting mypaint "binary" it cannot find the libmypaint to import.

i gave up and asked if anybody has correct instructions for compiling mypaint outside in the user's home: mypaint/mypaint#949

[jplloyd]

Closing this, as #949 is resolved.
