Running that make command yields:

$ make -C /Users/ehsan/moz/src.landing/obj-ff-dbg.noindex/toolkit/xre -s showbuild
Makefile:47: *** Variable GRE_BUILDID does not contain a value.  Stop.

This doesn't happen after doing a full rebuild.

You need to at least run `mach build export`. That's a known issue, and will be fixed by bug 1224450.

Thanks.  Should we close this as a dupe of bug 1224450 then?

Comment 4

[Mike Hommey [:glandium]]

The last patch on bug 1246881 will actually fix this.

Comment 5

[Mike Hommey [:glandium]]

Actually, since that last patch is not specifically bound to that bug, let's move it here.

Attachment: Only pass MOZ_BUILDID to the one source that requires it in toolkit/xre

Only pass MOZ_BUILDID to the one source that requires it in toolkit/xre

Seems reasonable, though this doesn't fix the issue in #c0 yet. (I have this patch & bug 1246881 applied). Is there something else I'm missing?

Comment 8

[Mike Hommey [:glandium]]

I thought it'd be enough, but bug 1224450 definitely fixes it anyways, so I won't look further why it's not enough.
