Found it.

During the various test with various kernels and imx-lib-versions (all 
unsuccesfull up to now) /usr/lib/libGAL-x11.so somehow changed from a 
symlink to a binary. The binary for 3.10.17. And it looks like my 
installation of libGAL 3.10.31 didn't overwrite that or whatever, I 
still have to search the reason.

Besides that, you sound like a new gpu-library is unable to deal with an 
old kernel. Not very nice as it ties userland to the kernel version.

Anyway, sorry for wrong error message.

But you have to deal with such, when the installation is as complicated 
as it currently is with all the various binary libraries and various 
necessary patches.

What makes it further complicated is, that I have to switch between 
mesa-opengl and imx-opengl for building various packages. For example 
the xorg-x11-server fails when building against imx-libraries (because 
it uses "-lGL -ldrm" and the imx-libraries do require "-ldrm -lGL").

It's really a pain to set that up.

So the opengl-stuff is currently a symlink-hell here I have to change 
quite often and I seem to have made a failure I didn't seen before. Even 
I've looked multiple times at the links and there target before posting 
the message, but Murphy is almost always present.

No.

I don't mix and match drivers, libraries or kernels. The kernel is
3.10.31, the library is 3.10.31 and the driver is 3.10.31 too. And I've
written that.

What I did was reverting commit 28a4a163b561c39ac0c798d420e0927f29e9d4c8
  "drm: platform multi-device support" in the 3.10.31 kernel. Had to do
this to let the x11-driver find the device. Maybe that is the reason why
the binary blob thinks it deals with an old kernel. But it's just
another assumption as I don't and can't know what the binary lib is
doing and how it decides (if it does that at all) with which kernel it
deals.

Besides that, you sound like a new library is unable to deal with an old
kernel.

If so, then there is for sure something wrong, because I see in kernel
3.10.31 the size mismatch and I'm using the xorg-driver 3.10.31 together
with gpu* 3.10.31 (as written before).
