heya,
got following error;

[jolsa@...va perf]$ make

Anyway, so you moved hex2u64, ctype interface under tools/lib
and made several Makefile changes to compile tools/lib objects.

Besides that we'd need all those changes separated, who is the
other user of this library? I dont see any in the patch.

thanks,
jirka
