1134511 - PKIX doesn't build with GCC 4.6 due to -pedantic-errors

Status: RESOLVED WONTFIX

(Core :: Security: PSM, defect)

Description

[Brian Birtles (:birtles)]

Bug 1128413 part 3 (https://hg.mozilla.org/mozilla-central/rev/d17a125c8ee7) appears to have turned on -pedantic-errors for GCC which causes problems building PKIX because of various enum macros that leave a trailing comma.

Build output for GCC 4.6.4 is as follows:

Comment 1

[Brian Smith (:briansmith, :bsmith, use NEEDINFO?)]

I am happy to review a patch that fixes this for GCC 4.6 by removing -pendantic-errors for GCC 4.6 (and/or 4.7). Let's leave it activated for GCC 4.8+ though.

Is there a way to turn it off?

With bug 1144155 landed and uplifted, as of Gecko 38, gcc-4.7 is now officially our minimum supported version.
