Hi Mike, Exciting! It looks like https://firefox-source-docs.mozilla.org/code-quality/coding-style/using_cxx_in_firefox_code.html will need an update to correct the "minimum supported version" declarations there for gcc/clang (and also to the features-that-we-can-use, I imagine?)
(source for that documentation is https://searchfox.org/firefox-main/source/docs/code-quality/coding-style/using_cxx_in_firefox_code.rst ) Thanks! ~Daniel On Wed, Aug 20, 2025 at 1:51 PM Mike Hommey <[email protected]> wrote: > Hi, > > With bug 1981918 and bug 1981921 now on firefox-main, the minimum > supported versions of GCC and Clang to build Firefox are, respectively, > 10 and 17, up from 8 and 8 (yes, they were coincidentally the same > version). > > For Firefox developers, this doesn't make much of a difference day to > day, except for the fact that they may experience less "base-toolchain" > build task failures (as those are using the minimum supported versions). > > For downstreams, this can mean you need to upgrade your build > toolchains, but we're not expecting massive disruption in the vast > majority of cases. > > See > https://firefox-source-docs.mozilla.org/build/buildsystem/toolchains-update-policy.html > for the rationale and how these will be updated in the future. > > Cheers, > > Mike > > -- > You received this message because you are subscribed to the Google Groups " > [email protected]" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To view this discussion visit > https://groups.google.com/a/mozilla.org/d/msgid/firefox-dev/20250820205100.i7rjlalbuwbycreh%40glandium.org > . > -- You received this message because you are subscribed to the Google Groups "[email protected]" group.
