           Summary: -rdynamic flag causes link failure on
                    x86_64-sun-solaris2.10
           Product: gdb
           Version: 7.2
            Status: NEW
          Severity: normal
          Priority: P2
         Component: build
        AssignedTo: unassigned@sourceware.org
        ReportedBy: tim.mooney@ndsu.edu


I'm building gdb-7.2 on x86_64-sun-solaris2.10 (Solaris 10 update6, *not*
OpenSolaris) with the Sun Workshop 12u1 tools.

configure is deciding that the "dynamic export flag" for the linker is
-rdynamic:

checking for the dynamic export flag... -rdynamic

However, the Solaris linker does not understand that flag, so linking later
fails:

cc -Xa -xs -g -xtarget=native -m64 -xarch=native -I/local/gnu/include

gmake[1]: Leaving directory `/local/src/RPM/BUILD/gdb-7.2'

Hacking the -rdynamic out of the relevant Makefiles allows the build to
proceed, but I'm not even certain what the intent is with the flag so I don't
know if there's flag that would be (somewhat) equivalent that I could instead
use with the Solaris ld.

This problem was not present with gdb-7.0.1.  I never tried gdb-7.1, so I don't
know if it was present there.

I just tested gdb-7.4, and this issue is still present there.  Updating version
to reflect that.
