meson build failing

When I try to build gnome-software from source I get this error:

meson.build:109:0: ERROR: Dependency “json-glib-1.0” not found, tried pkgconfig and cmake

If I try to install this package this is what I get: sudo apt install json-glib-1.0 Reading package lists… Done Building dependency tree Reading state information… Done Note, selecting ‘libjson-glib-1.0-0’ for regex ‘json-glib-1.0’ Note, selecting ‘libjson-glib-1.0-common’ for regex ‘json-glib-1.0’ libjson-glib-1.0-0 is already the newest version (1.4.4-2). libjson-glib-1.0-common is already the newest version (1.4.4-2).

So it looks like I have a newer version, but the build process doesn’t recognize it. How can I resolve this?

You need to install the development files package: libjson-glib-dev.

@ebassi That did it! Thanks!

I got further and now it is saying I am missing “malcontent-0”. Which library would that be? Thanks in advance!

The malcontent-0 pkg-config file is provided by libmalcontent. It’s currently not packaged on Debian, as far as I can see.

My suggestion is to use jhbuild, which builds and installs a project (and its dependencies) in a separate prefix, for development and testing.

Could you explain that or provide an example of how that will work?

I linked you to the jhbuild documentation, which comes with examples and explanation. Please, read that.
