No GPU options in system preferences?

I am on Linux Mint 11 with a Radeon HD 5770 and proprietary ATI drivers Catalyst 11.5
I would like to use the GPU rendering of Cycles, but I do not have any GPU option selectable in User Preferences > System > Compute Device. I just have the CPU option.
If I use Blender on Windows 7 on the same machine I do have the GPU option, so I suppose my video card should be compatible.
I know I can’t have CUDA option, but shouldn’t I have at least OpenCL option in Compute Device on Linux?
I guess I’m missing something trivial…
Wrong drivers maybe? :spin:

I have an installation of Ubuntu with a 5770 and the ATI 12.1 and i have no problems.

check the executable with a

 ldd /path/to/blender/executable

and update the driver, if you are in trouble use this wiki

I updated the driver to 12.1, but still no GPU option in Preferences > System > Compute Device.
This is the result of a ldd command on the blender executable (I do not really know how to check if something’s wrong): =>  (0x00007fff5fbff000) => /usr/lib/ (0x00007ff8fb3d3000) => /usr/lib/ (0x00007ff8fb164000) => /usr/lib/x86_64-linux-gnu/ (0x00007ff8faf3f000) => /lib/x86_64-linux-gnu/ (0x00007ff8fad18000) => /lib/x86_64-linux-gnu/ (0x00007ff8fab00000) => /usr/lib/x86_64-linux-gnu/ (0x00007ff8fa866000) => /lib/x86_64-linux-gnu/ (0x00007ff8fa663000) => /lib/x86_64-linux-gnu/ (0x00007ff8fa445000) => /usr/lib/x86_64-linux-gnu/ (0x00007ff8fa13e000) => /usr/lib/x86_64-linux-gnu/ (0x00007ff8f9e04000) => /usr/lib/x86_64-linux-gnu/ (0x00007ff8f9bf4000) => /usr/lib/x86_64-linux-gnu/ (0x00007ff8f99ed000) => /lib/x86_64-linux-gnu/ (0x00007ff8f97e9000) => /usr/lib/ (0x00007ff8f9278000) => /usr/lib/ (0x00007ff8f901f000) => /usr/lib/ (0x00007ff8f8d24000) => /usr/lib/ (0x00007ff8f8ae5000) => /usr/lib/ (0x00007ff8f887c000) => /usr/lib/ (0x00007ff8f85e6000) => /usr/lib/x86_64-linux-gnu/ (0x00007ff8f8383000) => /usr/lib/ (0x00007ff8f813f000) => /usr/lib/ (0x00007ff8f7f20000) => /usr/lib/ (0x00007ff8f7c5f000) => /usr/lib/ (0x00007ff8f7a57000) => /usr/lib/ (0x00007ff8f7851000) => /usr/lib/ (0x00007ff8f763c000) => /usr/lib/ (0x00007ff8f732c000) => /usr/lib/ (0x00007ff8f7128000) => /usr/lib/ (0x00007ff8f6f12000) => /usr/lib/ (0x00007ff8f6cf1000) => /lib/x86_64-linux-gnu/ (0x00007ff8f6ab5000) => /usr/lib/ (0x00007ff8f6761000) => /usr/lib/ (0x00007ff8f655c000) => /lib/x86_64-linux-gnu/ (0x00007ff8f61c8000) => /lib/x86_64-linux-gnu/ (0x00007ff8f5f43000) => /usr/lib/x86_64-linux-gnu/ (0x00007ff8f5d34000) => /lib/x86_64-linux-gnu/ (0x00007ff8f5b1e000) => /usr/lib/x86_64-linux-gnu/ (0x00007ff8f590c000)

I found the answer myself.
I just had to install the AMD APP SDK too… :o
