Subject: static musl-based gdb and -fPIC
Date: Sun, 20 Apr 2014 13:03:12 -0400 [thread overview]
Message-ID: <5353FDD0.6090903@midipix.org> (raw)
Greetings,
While building a statically linked musl-based gdb, ld asked that libc.a
be recompiled with -fPIC. After recompiling musl with the above flag,
gdb built successfully. The reason I wanted to have a static gdb (other
than the trivial ones) was to be able to debug a musl-based python. The
distribution's gdb has a dynamic dependency on a glibc-based libpython,
and the two friends don't play well together.
Now that the static gdb is up and running, my questions are:
1) is there any reason not to "always" compile musl with -fPIC, at least
on x86_64?
2) is there any reason to revert to the old build of libc.so? Although I
rebuilt musl because of libc.a, it turns out that the -fPIC flag also
helped libc.so become much smaller: 699299 bytes, instead of 2767910
bytes (musl v1.0.0, binutils v2.24). Any other factors to consider?
Thanks for looking at this,
zg
