Build platform is Ubuntu 12.04 x86_64

Confirmed by cviecco (same platform Ubuntu 12.04 x86_64)

In release-mode "ac_add_options --enable-optimize" the build is fine. - Nigel

I'm also getting this on Ubuntu 12.10 x86_64. Gcc version is: gcc (Ubuntu/Linaro 4.7.2-2ubuntu1) 4.7.2

(In reply to Karl Tomlinson (:karlt) from comment #6) > Created attachment 8376920 [details] [diff] [review] > use enum for BaseProxyHandler::Action values Hm, does this really work? I think I tried that, and had to ditch it because you can't OR enum values or something. Can you run your patch through try -b do -p all -u none -t none? r=me if that's green, but I suspect it isn't.

(In reply to Bobby Holley (:bholley) from comment #7) > Hm, does this really work? I think I tried that, and had to ditch it because > you can't OR enum values or something. You can't OR strongly typed (MOZ_ENUM_TYPE(Action)) enums because they won't be implicitly converted to another type, but plain old enums are implicitly converted, to int I think in this case, before the bitwise operation. > Can you run your patch through try -b > do -p all -u none -t none? r=me if that's green, but I suspect it isn't. Thanks. I'll put it through try, with some tests, when I have some more things to test.

Hi Bobby and Karl, I have the same build error on ubuntu 12.04 64bit. If we have OR operation concern, I suggest to use the original code. I just define these variable in cpp file. This patch works for me. -- The static member need to be "defined" outside of the class declaration.

Some build results, but need to another of my patches killed the NT builds. https://tbpl.mozilla.org/?tree=Try&rev=155dfdec56b7 https://tbpl.mozilla.org/?tree=Try&rev=a1f12431121d (In reply to Karl Tomlinson (:karlt) from comment #8) > strongly typed (MOZ_ENUM_TYPE(Action)) enums Actually MOZ_ENUM_TYPE() is not strongly typed, but the underlying type. MOZ_BEGIN_ENUM_CLASS is the strongly typed form.

Comment on attachment 8376920 [details] [diff] [review] use enum for BaseProxyHandler::Action values r=me on this if it does the trick.

Comment on attachment 8376954 [details] [diff] [review] js_BaseProxyHandler_build_error.patch I think the other patch is probably the way to go, assuming it works.

Successful builds on WINNT also. https://tbpl.mozilla.org/?tree=Try&rev=e41851a88ade https://tbpl.mozilla.org/?tree=Try&rev=17e4b2554586

Confirming that the build is now succeeding again on Ubuntu 12.04. As of git revision e0a06f0abb7d8baa0d649228ea367cf7a1f726cd. Thanks, all! - Nigel
