Installation of Vala

Install Vala by running the following commands:

[Note]

Note

If the recommended dependency Graphviz-2.40.1 is not installed, apply a patch. This will prevent building the valadoc program and libraries that can be used to generate API documentation in HTML format from Vala source code. 

patch -p1 -i ../vala-0.42.5-avoid_graphviz-1.patch &&
ACLOCAL= autoreconf -fiv

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

To test the results, issue: make check.

Now, as the root user: 

make install
