Bug 276377 – <=kde-base/kmail-4.4.0 fails to compile with -j > 1: dependency issue in generated makefiles

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Tanktalus 2009-07-03 15:27:08 UTC]

According to ABCD in IRC, I'm filing this.

Basically, kmail failed to compile giving:

make[2]: *** No rule to make target `kmail/org.kde.kmail.kmail.xml', needed by `kontact/plugins/kmail/kmailinterface.cpp'.  Stop.

When I add "-j1" to the MAKEOPTS in /etc/portage/env/kde-base/kmail, kmail completes successfully.  Ideally, the dependencies would get fixed upstream, but, in the meantime, adding "-j1" to the make command in kmail may be sufficient.

Reproducible: Always

There is a temporary fix (-j1) in the ebuild, and a bug has been filed upstream at <https://bugs.kde.org/show_bug.cgi?id=198807>.

[Comment 2 Tanktalus 2009-11-23 17:22:00 UTC]

I took out the -j1 option from my kmail-4.3.3 ebuild, and rebuilt it.  It rebuilt fine.  It looks like upstream did fix this bug between 4.2.95 and 4.3.3.

Thanks :-)

(I'd mark this bug fixed, but I think that we should now be able to remove the -j1 flag before closing it.)

I just checked, and it still can fail with current trunk (that doesn't mean it will always fail, or even will usually fail, but it *can* fail due to underspecified dependencies).

If this is only a compile problem, we can add an ewarn in the ebuild. But this can be done if this is only a compile problem, not if it also causes any runtime issues. Kmail takes a long time to compile now, so i guess it would be the best option atm, since upstream doesn't seem to care that much about this

[Comment 5 Jonathan Callen (RETIRED) 2009-11-25 19:52:15 UTC]

As far as I can tell, it's a compile-time only issue.  The main problem is that if make tries to build certain files in kontact/plugins/kmail/ before other files in kmail/, it fails (and there is no way that I am aware of to create the proper dependencies in cmake, unfortunately).

Seems to work fine with my -j9 on kde 4.4.2. 
But then, this is a non-deterministic bug class... :)

Did you edit the ebuild to remove the "-j1" bit - otherwise, you *didn't* test with -j9. (I think this may have been fixed for 4.5, but I haven't actually checked yet)

In the beginning, no. Now I did it...

Worked fine for kmail-4.4.2 two times in a row with -j9
(and top really displayed the concurrent compilers... :)

[Comment 9 Andreas K. Hüttel 2010-06-04 19:29:44 UTC]

I commented out the "-j1" lines in the ebuild for 4.4.4. When this moves to the tree, we'll get some more testing...

Nobody screaming so let's assume this is fixed.
