[gentoo-user] Unable to emerge kdebase/kfilereplace-4.3.5

[Thomas Revell]

Hi everyone,

I've got a bit of a problem with a new Gentoo install that I'm currently 
trying to install KDE on. The installation of kdebase/kfilereplace-4.3.5 
is failing, apparently due to a missing header file in its sources.The 
full build log is as follows:

According to http://bugs.gentoo.org/ there are no open bugs against this 
package (and in fact no bugs at all against the package since 2008), and 
I haven't been able to find anything by Googling.

Does anyone have any thoughts as to what I could try?

Thanks,

I have no idea what's going wrong, but I'm willing to make suggestions
anyway :)

The two lines of compiler output above show that the missing header file
is supposed to be generated on the fly by the qt/moc tools.  That means
that the header file is not actually being generated, or maybe (but not
likely) being generated in the wrong directory.

I don't know much about the kde/qt build system, but it seems to involve
the automoc and cmake packages as well as qmake, which is part of qt-core.

For lack of anything better to suggest, I would try the good old shotgun
technique of recompiling every package that has to do with building kde
and qt packages, e.g. automoc, cmake, qt-core, and maybe more that I know
nothing about.

In particular, though, I always suspect that old, stale, leftover files
from previous versions of related packages like qt and kde may be fouling
things up.  I pay close attention to the dates on files in /usr/include/*
and /usr/qt and /usr/kde and /usr/lib/qt and /usr/lib/kde to see if there
are just a few files with the same (old) date.  Oh, and /usr/lib/pkgconfig
is worth a look also.

Meanwhile, hope for someone to give you a better answer.

I have no better suggestion than to change your ricer CFLAGS and see if
"-O2 -pipe -march=core2" works first. Especially since you have:

 "-mno-align-stringops -minline-stringops-dynamically"

and kfilereplace.cpp:37 warns about QStringList& and further along, it
creates kaddstringdlgs.h.

BTW, -march=core2 implies -mmmx -msse -msse2 and -msse3 (and -mssse3).

  Even better is "-march=native", and let the compiler figure out what
features are available/safe.  I use the following...

CFLAGS="-O2 -march=native -mfpmath=sse -fomit-frame-pointer -pipe"

If you're building 64-bit Gentoo, the "-mfpmath=sse" gets picked up by
"-march=native" and you can drop the explicit mention.

  And you wouldn't believe how many weird build problems are solved by...

MAKEOPTS="-j1"

...even on multi-core cpus.  The *BUILD PROCESS* is a bit slower, but
the final binary is identical with -j8 or whatever.  And the time you
"save" by a faster build in a tty will be lost the first time you start
bashing your head into a brick wall over some weird build problem.

Exactly. And the same with distcc. If you do not use --keep-going,
you'll likely see that long compile end abruptly. My typical modus
operandii is to use distcc, then compile locally, then just use -j1
locally. You get there but you have to be willing to babysit it.

For example, I just upgraded two of my VMs to gcc 4.4 so I will
recompile "-qe world" on them. Since it's the weekend, I'll just turn
off distcc and let them run -j1. When I come back on Monday, I expect to
see a sparkling clean and shiny new Gentoo VM. Well, I can at least
hope! I'll probably run out of inodes or something....
