I try to build kde from svn and I follow this guide. But I face this problem, when I run :

Code: Select all

cmake /home/kde-devel/kde/src/KDE/kdelibs/

I get this error:

CMake Error at cmake/modules/FindKDE4Internal.cmake:321 (message):
Your version of automoc4 is too old. You have 0.9.84, you need at least
0.9.87

I try to export CMAKE_PREFIX_PATH=/home/kde-devel/kde/lib/ but it does not work.

any hints ?

you may need to pass it directly to cmake like so "cmake /home/kde-devel/kde/src/KDE/kdelibs/ -DCMAKE_PREFIX_PATH=/home/kde-devel/kde/src/KDE/kdelibs/". Alternatively you may need to update your system version of automoc4 to a newer version of Qt, either by distro packages or by building qt-copy from svn.

well the problem that the places it looks for it is hardcoded in the cmake files..

i made a check install of a svn version of automoc4 and then copied the bin file to where my system automoc4 was and moved my system version of it to automc4.bak so that it would be replaced by your new compiled one..

there is probably some better more elegant way to do it but yeah it was an esy no brainer way to do it:P

Than you !!

I do like of_darkness and it is work.

and you may have 2 do it again at some point, i got 2 do it as one thing neaded a even newer version.. but its preaty easy 2 do so:)

although its not specialy elagant way 2 do it:/

I suggest building all of kdesupport forom trunk, so you wan't have any more troubles like this. (As well stated in tutorial u gave link for).

Also, your interpretation of tutorial you gave is way different than what it's supposed to be
("cmake /home/kde-devel/kde/src/KDE/kdelibs/ " instead of a simple "cmakekde" with all the variables well noted in .bashrc ? )

Also, I even build cmake from SVN as latest snapshots has some additional modules available.

Actually I build all of kdesupport from trunk

from same tutorial : There might be missing dependencies on your system! They are easily overlooked in the output of cmakekde. You might want to do a cmake $KDE_SRC/KDE/MODULE_NAME prior to compiling any kde modules (like kdelibs, kdepimlibs etc.)

The problem is the place of automoc4 is hardcoded in the cmake files !

Zayed, automoc4 is a part of kdesupport, so if have built it correctly an it is in your $PATH, you shouldn't have this problem.

As well stated in your error output:

Your version of automoc4 is too old. You have 0.9.84, you need at least
0.9.87

you don't have a problem with CMake but with automoc4, which tells me that your $PATH might be wrong.

My trunk build goes to opt, so my $PATH looks like this: /opt/qtcopy/bin:/opt/kde/bin:/bin:/usr/bin..... etc.
So, for example, if I have my distro automoc4 and the one I compiled with kdesupport, the one I compiled will be used first.

Just do:

Code: Select all

echo $PATH

or

Code: Select all

which automoc4

and you'll se for yourself

@Githzerai

I suffered this today and took me a while to remember how to fix it: uninstall distro's package automoc.

I do have the path correctly set for development.
$ which automoc4
/home/kde/KDE/bin/automoc4

But, when the distribution package is installed, /usr/bin/automoc4 is found instead.

Uninstalling your distro's package should not be needed. you just need to set $PATH correctly. correctly means that it refers to your KDE4 trunk first.
to do this just stick the path to your trunk binaries ( eg: /opt/kde4-trunk/bin )
first ( PATH=/opt/kde4-trunk/bin;$PATH )
