I installed the amd app sdk last night (Linux 64) and for some reason, it seems like it skipped over the most important file - libOpenCL.so.1
I let the installer use its own default directories, I didn't tell it to do anything special. I tried to compile some little sample opencl code which failed on linking. I could find a link to libOpenCL.so.1 in /opt/AMDAPPSKD-3.0/lib/x86_64/ but the link there points to /usr/lib/libOpenCL.so.1, which doesn't exist. I found the actual file in /opt/AMDAPPSDK-3.0/lib/x86_64/sdk/ and I manually copied it to my /usr/lib/ which seemed to fix nearly all of my issues. Is this normal behavior? Assuming this package is targeting ubuntu, does ubuntu put libraries somewhere else?
I went digging around in the 'install.sh' which lives in the installed directory of the amdappsdk. Curious that it installs its install script along with everything else, but moving past that.... I found this:
#Function Name: createOpenCLSoftLink
#Comments : creates the soft-link libOpenCL.so to libOpenCL.so.1
# This is done depending upon the libOpenCL.so file.
# If libOpenCL.so exist we are doing nothing.
# If only libOpenCL.so.1 is present in /usr/lib, then we are creating the soft-link libOpenCL.so to libOpenCL.so.1
# The libOpenCL.so* file are created depending upon the catalyst installation, so to handle this we are creating soft-link
# And libOpenCL.so is required by cmake files to pick the catalyst runtimes.
# If libOpenCL.so file is not found in /usr/lib, then cmake picks up the AMDAPPSDK runtimes.
Without getting too far in the weeds, I imagine the way in which libOpenCL.so.1 is handled it must have been intentional, but it seems really strange. Either way, the soft-linking seems to fail. Is there a reason we're not just moving the right file into the right place? Is this to account for other opencl implementations to avoid accidental over-write?
Looking at the whole amdappsdk package, it's amazingly complex. I guess it has to account for all kinds of environments, but this all seems like a lot and I suppose the amdappsdk does more than "just" opencl but...my god these scripts go on forever.
I think, Pulkit Lall referred to the latest APP SDK 3.0 available here: http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/ . Just make sure you are using the above one not the beta version of APP SDK 3.0 available earlier.
