The saga continues.... the -O0 was a blind alley... The build for kdelibs
is now proceeding nicely.
I visited one of the more helpful channels on irc, and discussed this
situation. They advised that it might really be a problem with swap space
after all. While I initially claimed to have 128mb of swap space, one of the
regulars suggested I monitor it with the free command or with gkrellm. When
I reported the values from free as Swap 0, 0, 0 someone immeditately
recognized that I did not have swap turned on.
While I did find the following in the boot log: /var/log/boot.log:Nov 21
20:24:33 localhost rc.sysinit: Enabling swap space succeeded, swapping was
still not happening. the reason was the lack of a swap entry in /etc/fstab.
(don't ask why its not there, it just wasn't ok?)
The correct /etc/fstab entry in my case:
/dev/hda11 none swap sw
To make swapping start in the current session I gave the command
swapon /dev/hda11
Bottom line for KDE Build, no -O0 is needed. the build of kdelib is working
just fine with just
export QTDIR=/usr/lib/qt-2.1.1
cd /usr/src/kdelibs-2.0
make -f Makefile.cvs
./configure --enable-debug
make
I'm mid build now and free is reporting:
total used free shared buffers cached
Mem: 126628 108660 17968 37564 3868 22912
-/+ buffers/cache: 81880 44748
Swap: 131064 4392 126672
before the build, swap was 131064 0 131064, no swap used, but 128mb
available.
