           Summary: The -static-libstdc++ does not work on HP-UX (IA64
                    B.11.23, probably others)
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jvb@cyberscience.com
              Host: HP-UX IA64
            Target: HP-UX IA64


The -static-libstdc++ option is silently ignored on HP-IX, IA64 platform.

The reason for this seems to be that g++spec.c relies on HAVE_LD_STATIC_DYNAMIC
from auto-host.h, and if this is not set silently fails to implement
-static-libstdc++.

The HP linker does have options to implement HAVE_LD_STATIC_DYNAMIC, but
configure has not detected them. Presumably this is because they are not the
usual -Bstatic and -Bdynamic, the HP options are -aarchive and -ashared_archive
(not -ashared which disables archive libs completely). Changing auto-host.h to
use:

  #define HAVE_LD_STATIC_DYNAMIC 1
  #define LD_DYNAMIC_OPTION "-ashared_archive"
  #define LD_STATIC_OPTION "-aarchive"

resolves the issue, but of course is not the right fix since this file is
generated. So, this is really a configuration time issue.

As an additional fix though, I would really expect g++ to error or warn if
-static-libstdc++ can't be implemented, instead of silently ignoring. Also it
could provide the archive name to the linker in place of -lstdc++ for systems
where HAVE_LD_STATIC_DYNAMIC really doesn't exist - but possibly if this were
fixed for HP there might not be any systems with this restriction.

A patch for this has been submitted to gcc-patches@gcc.gnu.org.

http://gcc.gnu.org/ml/gcc-patches/2011-07/msg02704.html

I am waiting for approval of the gcc.c part that is needed to handle the fact
that there is no static system unwind library on HP-UX.
