Colleagues,
I'm trying to build Ruby under Owl, and I've got the following:

/usr/lib/gcc/i686-openwall-linux/4.6.3/../../../libssp.a(ssp.o): In
Afaik glibc should already come with its own libssp, so having it in gcc
as well is redundant (there's a configure flag for that, which should be
set automatically when using glibc, but it can be overridden like this:
gcc_cv_libc_provides_ssp=yes make ... when building gcc).
Your issue comes from -pie tho which pulls in __stack_chk_fail_local
(and that one should be only in libssp_nonshared.a).
so it seems your gcc was incorrectly configured.
maybe Rich (CC'ed) knows more details ?
either way, removing -pie from the CFLAGS should work around the issue.
function `__stack_chk_fail_local':
(.text+0x170): multiple definition of `__stack_chk_fail_local'
/usr/lib/gcc/i686-openwall-linux/4.6.3/../../../libssp_nonshared.a(libssp_nonshared_la-ssp-local.o):(.text+0x0):

make: *** [miniruby] Error 1
This seems to be a long-known bug somehow related to gcc, see, for
example, here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35377 -- but
here the 4.2.3 is discussed, while I'm using 4.6.3 (which is in Owl), so
perhaps replacing gcc with another version will not solve the problem.
Any ideas? May be someone has prebuild packages of Ruby for Owl?
