The libOpenCL.so in /usr/lib32 is missing in Catalyst 12.8.
If you are running a 32bit version of your OS you need to set the path to x86 instead of x86_64. If you get an error message saying something like “error while loading shared libraries: libOpenCL.so: cannot open shared object file: No such file or directory” you have forgotten to set the LD_LIBRARY_PATH above.
Nah, I am on 64 bit. Just saying that the installer is not installing the 32 bit OpenCL library as Catalyst 12.6 (and all other before) did. I can no longer compile 32 bit binaries from my 64 bit Host.
Just found a way to help myself. If someone ever has the same problem:
Extract the stuff without install:
./amd-driver-installer-8.982-x86.x86_64.run --extract p
Then everything is in p/arch/x86/usr/lib/
