Amd ADL library not found · Issue #139 · nanopool/Claymore-Dual-Miner · GitHub
There is actually no problems, because it's searching for a specific set of library files that is only necessary in Fedora:
I did a strace on the miner and this is the output:
open("/lib/x86_64-linux-gnu/libatiadlxx.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/usr/lib/x86_64-linux-gnu/libatiadlxx.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/lib/libatiadlxx.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/usr/lib/libatiadlxx.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) munmap(0x7f6567dda000, 146284) = 0 write(1, "\33[0mAMD ADL library not found.\n", 31) = 31

Issue is resolved ! The miner is operating just as it should, the error can be ignored for Ubuntu , otherwise if you're running Fedora you can download those necessary lib files.
