Can you post a link to the spkg. I've installed Sun Studio 12 update 1
on my machine at home, which installs the Sun compilers in a different
directory to on 't2'. For some reason Sun changed the default from
/opt/SWUNspro which they have used for years, to /opt/sunstudio12.1
I note that this also add '-m64' as a linker flag if SAGE64 is set to
'yes'. Looking at one .spkg (not your latest), I see in one of the patches:
--------------------------------------------------------
-opts.Add('LINKFLAGS', "Linker flags", ['-s'], converter = Split)
+#The following linker flags causes the build to fail on OSX 10.4, but
works on 10.5
+# opts.Add('LINKFLAGS', "Linker flags", ['-s'], converter = Split)
+# Instead we add "-m64" in case we build on multiarch in 64 bit mode
(OSX now, Solaris later)
+if os.environ['SAGE64'] == "yes":
+ opts.Add('LINKFLAGS', "Linker flags", ['-m64'], converter = Split)
+#End modifications
opts.Add('LIBS', 'custom libraries needed for build', [], converter =
Split)
--------------------------------------------------------
But to my knowledge, there is no such linker flag as '-m64', either with
the GNU or Sun linkers. The Sun linker support '-64' but this is rarely
needed, as the linker is normally able to determine if a 64-bit library
or executable is needed based on whether the objects files are 32 or
64-bit. The only exception I'm aware of is when one builds a shared
library from a static library. I don't see anything even remotely
similar with the GNU linker. I've just looked on an OSX box, and don't
see any such option there either.
