Status: RESOLVED DUPLICATE of bug 1040124

(Firefox Build System :: General, defect)

Description

[Jan Keromnes [:janx]]

Just rebased to master, and can't build on Ubuntu anymore:

On Ubuntu 12.04, even after a renewed `./mach bootstrap`.

Chromium solved this by "Explicitly includ[ing] gmodule-2.0 in the list for glib/gtk dependency." (http://crbug.com/115799 in "See also").

[Jan Keromnes [:janx]]

Build works on > 12.04, looks like an Ubuntu Precise specific bug.

Comment 3

[Mike Hommey [:glandium]]

That error means the gtk library itself doesn't have a dependency on gmodule. Not a problem in the Firefox build system.

Comment 4

[Jan Keromnes [:janx]]

This problem was introduced by bug 983504's build system change, making me unable to build firefox on Ubuntu Precise.

Chromium fixed their build system by adding the dependency, so that it works even on misconfigured systems:

http://src.chromium.org/viewvc/chrome/trunk/src/build/linux/system.gyp?r1=126148&r2=126147&pathrev=126148

Do we really want to consider a broken build on a LTS Ubuntu (supported until late 2017) invalid?

Attachment: gtk+-x11-2.0.pc.diff

Even if this isn't a bug per se, it's still irritating having your build machine stop building suddenly. In any case, here's a fix, if you happen to run Ubuntu 12.04 (64 bits). Just copy the attached file to your machine somewhere and execute

sudo patch /usr/lib/x86_64-linux-gnu/pkgconfig/gtk+-x11-2.0.pc thisfile.diff

If you prefer to do it manually, search for the gtk+-x11-2.0.pc file under /usr/lib and add -lgmodule-2.0 to the Libs: line

[Jan Keromnes [:janx]]

Thanks for the fix Antonio!

On my side I've managed to fix the build by backing out offending patches from bug 983504:

> Bug 983504 - Buildsystem changes for screen sharing. r=ted
> Bug 983504 - Modify constraints for screen sharing. r=bholley,jib
> Bug 983504 - Enumeration & MediaEngine changes for screen sharing. r=jesup,mt
> Bug 983504 - ViECapturer changes for screen sharing. r=jesup
> Bug 983504 - ViEInputManager & config changes for screen sharing. r=gcp

"Enumeration & MediaEngine" has a minor conflict that is easy to fix, and after that firefox builds again.
