Hi there,
I am currently developing ebuilds for mali drivers for the Odroid U2. I know that there are some more general mali ebuilds around, but I'd like to base these ebuilds on the files provided by hardkernel, thus I started this work.
Anyway, I managed to create one ebuild, which installs the desired files in the necessary places, e.g. in /usr/lib/opengl/mali/*/:
| Code: |
odroid lib # pwd
/usr/lib/opengl/mali/lib
odroid lib # ls -l
insgesamt 740
lrwxrwxrwx 1 root root 11 19. Apr 09:08 libEGL.so -> libEGL.so.1
lrwxrwxrwx 1 root root 13 19. Apr 09:08 libEGL.so.1 -> libEGL.so.1.4

The mesa GL libs are linked due to the fact that mali is only able to provide EGL and OpenGL ES, but no pure OpenGL.
However, when I switch to the opengl mali interface via 'eselect opengl set mali', I get the following:
| Code: |
odroid lib # pwd
/usr/lib
odroid lib # ls -l *GL*
lrwxrwxrwx 1 root root 26 19. Apr 09:08 libEGL.so -> opengl/mali/lib/libMali.so
lrwxrwxrwx 1 root root 34 19. Apr 09:08 libGL.so -> opengl/xorg-x11/lib/libGL.so.1.2.0

lrwxrwxrwx 1 root root 26 19. Apr 09:08 libGLESv2.so -> opengl/mali/lib/libMali.so

If you compare both snippets, you will see that only one link for each libEGL, libGLESv1_CM and libGLESv2 is provided, whilst for libGL both links are there. Mainly, there are no links with numbers after *.so, such as e.g. libEGL.so.1. Apparently, some applications need these links.
For comparison reasons, here is the same output with 'eselect opengl set xorg-x11':

As you can see, the *.so.X links are set correctly for xorg-x11 by eselect opengl.
What am I doing wrong with the mali files here?
Thanks a lot.

| Well, the problem was, that the libraries were lacking their sonames. |
