Hi Craig, thanks for the response.
I just don't understand why this symbol (__libc_stack_end) is being
required by the binary. According to what I've read:
"__libc_stack_end is part of glibc private interface, libraries other
then the ones contained in glibc or programs must not use it.
The private interfaces has been moved to GLIBC_PRIVATE symbol version
to catch broken programs/libraries and also to document what is and what
is not considered to be private interface in a clear way."
(http://sources.redhat.com/ml/libc-alpha/2002-10/msg00115.html)
It shouldn't matter if you've compiled on a host that uses Glibc 2.1 or
Glibc 2.3, that symbol is considered private and shouldn't be in the list
of symbols required by the application.
It might be worth the time to try compiling under a system with a newer
version of glibc, just to see what gets caught at compile time.
