Hi Frank,
I met a issue with build systemtap. Build it need (install elfutils-devel, libebl-dev, libdw-dev and/or libebl-devel), but ubuntu looks don't have it.
I try to build elfutils-0.148 with myself, but after I install it, when I compile other code, I got: /usr/local/bin/ld: /usr/lib/libelf.so.1: version `ELFUTILS_1.5' not found (required by /usr/local/bin/ld) collect2: ld returned 1 exit status It really scared me.
Did you meet this issue in before?
Thanks, Hui
