The default ports gcc for USE_GCC is still 4.8, which does not support -fstack-protector-strong. This breaks several ports including (from

r288669 only applies to base. It was tested with an exp-run and there were
no
failures so this is something wrong in your setup.

Ugh ... now that I remember, we actually used -stack-protector-all for the
exp-run
(which is supported in pretty much every gcc).

Still, the change should only apply to the base system and not ports, and
-stack-protector-strong appears to have been backported to gcc48
last year (see PR 186852).

cheers,

Pedro.

All I can say is building with USE_GCC=yes, I see the following error:

g++48: error: unrecognized command line option '-fstack-protector- strong'

This is using the latest gcc48 in ports (full tree updated yesterday).

OK, I tested graphics/libfpx on i386-current:

-stack-protector-strong indeed gets pulled in due to some non-orthodox
workarounds in files/Makefile.bsd.

g++48 accepts it just fine and the port compiles.

Is this a platform that has GCC issues, perhaps? It looks like one of those
"unfortunately series of events" that may have to be fixed in the port
and/or gcc48.

Pedro.


This is on powerpc64. I see the patch has been there for 16 months, but for some reason, the /usr/local/bin/gcc48 doesn't contain the patch. I ran `strings` on the binary, and it has the following string:

%{fstack-protector|fstack-protector-all:-lssp_nonshared}

Which, if you examine files/patch-stackprotector-gcc, is the unpatched string.

I have no idea why this is the case.
