I don't even see any indication that boinc is attempting to open an opencl
library before pronouncing that there isn't one. stderrgpudetect.txt and
stdoutgpudetect.txt are empty.
>From an strace of boinc --detect_gpus here are the directories searched...
open("/lib64/tls/libOpenCL.so", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("/lib64/libOpenCL.so", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("/usr/lib64/tls/libOpenCL.so", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("/usr/lib64/libOpenCL.so", O_RDONLY) = -1 ENOENT (No such file or
directory)
>From cat /etc/ld.so.conf.d/*.conf, here's what should have been
searched...
/usr/lib64/atlas
/usr/lib64/ctapi
/usr/lib/llvm
/usr/lib64/llvm
/usr/lib64/mysql
/usr/lib64/nvidia
/usr/lib/nvidia
/usr/lib64/qt-3.3/lib
/usr/lib/wine/
/usr/lib64/xulrunner
and the defaults (/usr/lib64,/lib64)
Adding /usr/lib64 to LD_LIBRARY_PATH solved the problem, but shouldn't have
been necessary.
