Missing Library

Question

I'm trying to get into developing for Elementary using Vala. I have been unsuccessfully trying to build Valama (an IDE for Vala) for ages but keep hitting hurdles.

Currently when I try to make Valama (having satisfied all dependencies) I get the following error:

error: Package 'webkit2gtk-3.0' not found in specified Vala API directories or GObject-Introspection GIR directories

I have apt-get install'd both webkit2gtk-3.0 and webkit2gtk-3.0-dev but the error persists. Any idea how to fix this?

Answer 1

For this kind of errors I always search in the AUR for missing dependencies, when I install all the dependencies the problem, most of times fixes, if not you should read the oficial git/webpage because maybe it can have bugs. So check out if you have installed this packages:

• clutter-gtk
• gdk-pixbuf2
• gdl
• glade
• glib2
• gtksourceview3
• intltool
• libgee
• webkit2gtk
• cmake
• imagemagick
• vala-0.26

I hope this information will help you, for me worked like a charm.

Answer 2

The error message is coming from the Vala compiler and suggests the VAPI file is not being found for webkit2gtk-3.0. It looks likes Valama fixed this by adding webkit2gtk-3.0.vapi to its repository with this commit:

CMake: Add webkit2gtk-3.0 vapi to support vala < 0.26

Maybe that helps you a little. I tried building Valama on Fedora 23, but CMake reports:

-- Package 'webkit2gtk-3.0' not found CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:360 (message): A required package was not found

This is to do with the pkg-config file webkit2gtk-3.0.pc not being found. I didn't try any futher to repeat the error message you are getting.
