[Builder] Error building gnome-builder from gnome-builder

[Jose Antonio Velasco <velascopja gmail com>]

Hi!

I'm new to gnome-builder and I'm trying to install it on Elementary OS in order to try to contribute to the project (if I'm able...) So far, I've installed gnome-builder through jhbuild and I'm able to open gnome-builder project in gnome-builder, but when I try to build the project I get this error message:

configure: error: Package requirements (glib-2.0 >= 2.50.0

gmodule-2.0 >= 2.50.0

gtk+-3.0 >= 3.22.1) were not met:

Requested 'glib-2.0 >= 2.50.0' but version of GLib is 2.48.2

Requested 'gmodule-2.0 >= 2.50.0' but version of GModule is 2.48.2

Requested 'gtk+-3.0 >= 3.22.1' but version of GTK+ is 3.18.9

Consider adjusting the PKG_CONFIG_PATH environment variable if you

installed software in a non-standard prefix.

Alternatively, you may set the environment variables EGG_CFLAGS

and EGG_LIBS to avoid the need to call pkg-config.

See the pkg-config man page for more details.

Any help would be very much appreciate.

Thank you very much!

Best regards.
