Beyond Linux® From Scratch - Version 8.3

Chapter 13. Programming

Vala-0.40.8

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

Required

Installation of Vala

Install Vala by running the following commands:

[Note]

Note

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'  configure.ac &&
sed -i '/valadoc/d' Makefile.am                 &&
ACLOCAL= autoreconf -fiv

./configure --prefix=/usr &&
make

To test the results, issue: make check.

Now, as the root user: 

make install
