I was attempting to build a customized libc6.1 package on Alpha to
work around Bug#325600 -- libc6.1: Threads remain <defunct> on Alpha
with libc6. 2.3.5-4. (Interested parties should also see
http://sources.redhat.com/bugzilla/show_bug.cgi?id=1297 where this
issue has been declared CLOSED - WONTFIX, which I speculate would not
be the case if x86 were affected :-( ). The build was failing during
the -DPROF compile of elf/dl-runtime.c with the following error:
dl-runtime.c:222: error: '_dl_runtime_profile' aliased to undefined symbol
'_dl_runtime_resolve'
As a workaround, I modified sysdeps/alpha/dl-machine.h as follows:
strong_alias (_dl_runtime_resolve, _dl_runtime_profile);
was replaced by
asm (".globl _dl_runtime_profile\n" \
"_dl_runtime_profile = _dl_runtime_resolve");
as inferred from include/libc-symbols.h.
'gcc -v' output:
