Cogl-1.22.2

Introduction to Cogl

Cogl is a modern 3D graphics API with associated utility APIs designed to expose the features of 3D graphics hardware using a direct state access API design, as opposed to the state-machine style of OpenGL.

This package is known to build and work properly using an LFS-8.0 platform.

Installation of Cogl

Install Cogl by running the following commands:

[Note]

Note

This package may occasionally fail when building with multiple processors. See Using Multiple Processors for more information. 

sed -i 's/^#if COGL/#ifdef COGL/' cogl/winsys/cogl-winsys-egl.c &&

./configure --prefix=/usr --enable-gles1 --enable-gles2         &&
make

To test the results, issue: make check. The tests should be run from an X terminal on the hardware accelerated Xorg Server.

Now, as the root user: 

make install
