Description

[Shao Hang Kao [:skao]]

I followed the instructions on MDN,

and got the following errors:

Please post a link (or links) to exactly which instructions you followed.

I've been building on OS X 10.9 for some months now, and have never seen these errors.  Nor have they (yet) been reported by anyone else.

My build system doesn't include any of the following files:

In file included from frameworks/base/tools/aapt/AaptAssets.cpp:5:
In file included from frameworks/base/tools/aapt/AaptAssets.h:10:
In file included from frameworks/base/include/utils/AssetManager.h:24:
In file included from frameworks/base/include/utils/AssetDir.h:24:
In file included from frameworks/base/include/utils/Vector.h:20:

Do you have any idea where they came from?

Comment 2

[Martin Gunnarsson]

I got the same problems following the instructions here: https://developer.mozilla.org/en-US/Firefox_OS/Firefox_OS_build_prerequisites

... and found the solution here: https://developer.mozilla.org/en-US/Firefox_OS/Building#clang_errors_when_building_with_XCode_5_on_Mac (under "clang errors when building with Xcode 5 on Mac").

Comment 3

[Steven Michaud [:smichaud] (Retired)]

Oops, I mistakenly thought this bug was about building Firefox, not Firefox OS.

Sorry for the confusion :-(

Comment 4

[Steven Michaud [:smichaud] (Retired)]

Skao, please try Martin's suggestion from comment #2.  If that works for you, please mark this bug WEORKSFORME.

Comment 5

[Shao Hang Kao [:skao]]

Will try it, thanks!

Comment 6

[Cédric de Saint Martin]

So, I tried this trick, and I have another error now:

[qemu compilation log above...]

Is anyone able to reproduce and confirm, so that we know if it comes from my environment?

Comment 7

[Gary Kwong [:gkw] [:nth10sd] (NOT official MoCo now)]

Cedric, your issue seems to be bug 935776, and yes, I hit it too, though I last tried a few weeks ago.

Comment 8

[Kartikaya Gupta (email:[e-mail])]

I ran into this problem too, and the instructions in the MDN page referenced in comment 2 fixed it for me. The patches on bug 935776 are intended to accomplish the same thing by updating the bootstrap/build scripts to install and use g++-4.6 by default. I'm going to dupe this bug over to that one since the patches there, if landed, would fix all the issues discussed in this bug.
