Introduction to Vala

Vala is a new programming language that aims to bring modern programming language features to GNOME developers without imposing any additional runtime requirements and without using a different ABI compared to applications and libraries written in C.

This package is known to build and work properly using an LFS-8.3 platform.

Package Information

Vala Dependencies




dbus-1.12.10 (Required for the tests), Graphviz-2.40.1 (Required for valadoc), libxslt-1.1.32 (Required for generating the documentation), help2man, and weasyprint

User Notes:

Installation of Vala

Install Vala by running the following commands:



The two sed commands and the autoreconf command below are required if the optional dependency Graphviz-2.40.1 is not installed. This will allow building the valadoc program and libraries that can be used to generate API documentation in HTML format from Vala source code.

sed -i '115d; 121,137d; 139,140d' &&
sed -i '/valadoc/d'                 &&
ACLOCAL= autoreconf -fiv
./configure --prefix=/usr &&

To test the results, issue: make check.

Now, as the root user:

make install
