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: Warning: Option -dynamic passed to ld, if ld is invoked, ignored otherwise
ld: fatal: option -d has illegal argument `ynamic'
ld: fatal: Flags processing errors

gmake[1]: *** [install-gdb] Error 2
gmake[1]: Leaving directory `/local/src/RPM/BUILD/gdb-7.2'
gmake: *** [install] Error 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.
