For quite some time now (seems like forever) I’ve used a bit modified scripts from Techbase: Increased Productivity in KDE4 with Scripts to build KDE.
I don’t know why, but I’ve never even tried kdesvn-build script, so the things I’ll write here are maybe (probably) already present in it.
So, if you don’t use kdesvn-build, and have your system set up like it is explained in the above link, keep reading.
Important: I’m using ZSH, so the scripts here maybe need changing in order to be usable in BASH.
Environment
First of all, we need to add some global, environment variables. You should put this in the script for setting KDE4 variables (for example in .my-setup)
The first variable will be used by the build logging system. You should define it near the definitions of KDE_SRC and KDE_BUILD variables.
# build and src folders
# you might want to change these!
export KDE_BUILD=$KDE4ROOT/build
export KDE_SRC=$KDE4ROOT/src
export KDE_LOG=$KDE4ROOT/log
After this, we are making a variable that holds all the dirs to be included in the automatic build system.
# all build dirs
KDE_BUILD_DIRS=""
pushd $KDE_SRC > /dev/null
for dir in \
KDE/support \
KDE/libs \
KDE/pimlibs \
KDE/base \
KDE/plasmoids \
KDE/pim \
KDE/accessibility \
KDE/artwork \
KDE/bindings \
KDE/graphics \
KDE/multimedia \
KDE/network \
KDE/sdk \
KDE/utils \
\
extragear/* \
other/* \
playground/* \
;
do
KDE_BUILD_DIRS="$KDE_BUILD_DIRS $dir";
done
popd > /dev/null
export KDE_BUILD_DIRS
SVN/GIT Updates
Now, we can create two very easy functions for fetching the updates:
function updatesource {
if [ -n "$1" ]; then
cd $1;
fi
if [ -d .svn ]; then echo "Updating directory: $PWD (svn)"; svn up; fi
if [ -d .git ]; then echo "Updating directory: $PWD (git)"; git pull; fi
}
function kdeup {
# clearing update logs
rm -fr $KDE_LOG/update.log
rm -fr $KDE_LOG/*.update
cd $KDE_SRC
for dir in `echo $KDE_BUILD_DIRS`; do
updatesource $KDE_SRC/$dir || echo "$dir (see $log_file) update failed" >> $KDE_LOG/update.log
done
}
Notice that it reports errors in $KDE_LOG/update.log file.
Building
Now we define kdemake command which will build all the directories we specified in $KDE_BUILD_DIRS. Like kdeup, it logs the process. The main log is $KDE_LOG/build.log and each built directory has its own build log (the output of cmake + make).
function kdemake {
# clearing all logs
rm -fr $KDE_LOG/build.log
rm -fr $KDE_LOG/*.build
cd $KDE_SRC
for dir in `echo $KDE_BUILD_DIRS`; do
cd $KDE_SRC/$dir;
echo "Building $dir";
log_file=`echo $dir | sed 's/\//_/g'`;
log_file="$KDE_LOG/$log_file.build";
echo "Building $dir > $log_file" > $log_file;
echo "Building $dir" >> $KDE_LOG/build.log
( ( cmakekde || echo "FAILED: see $log_file" >> $KDE_LOG/build.log ) 2> /dev/stdout | tee -a $log_file )
done
}
Debug builds
Sometimes you want to have a certain module build with debugging symbols – just replace the default cmakekde function with this one. It checks for the .debug file and if it exists, it builds that module with dbg symbols included.
function cmakekde {
if test -n "$1"; then
# srcFolder is defined via command line argument
srcFolder="$1"
else
# get srcFolder for current dir
srcFolder=`pwd | sed -e s,$KDE_BUILD,$KDE_SRC,`
fi
# we are in the src folder, change to build directory
# Alternatively, we could just use makeobj in the commands below...
current=`pwd`
if [ "$srcFolder" = "$current" ]; then
cb
fi
# to enable tests, add -DKDE4_BUILD_TESTS=TRUE to the next line.
# you can also change "debugfull" to "debug" to save disk space.
# added "nice make..." to allow the user to work on the box while
# compiling
# Note: To speed up compiling, change 'make -j2' to 'make -jx',
# where x is your number of processors +1
if test -e ".debug"; then
echo "debug yes" && \
cmake "$srcFolder" -GKDevelop3 -DCMAKE_INSTALL_PREFIX=$KDEDIR \
-DCMAKE_BUILD_TYPE=debugfull \
&& nice make -j3 && make install
elif test -e ".debug-release"; then
echo "debug yes [release-debug]" && \
cmake "$srcFolder" -GKDevelop3 -DCMAKE_INSTALL_PREFIX=$KDEDIR \
-DCMAKE_BUILD_TYPE=RelWithDebInfo \
&& nice make -j3 && make install
else
echo "debug no" && \
cmake "$srcFolder" -GKDevelop3 -DCMAKE_INSTALL_PREFIX=$KDEDIR \
-DCMAKE_BUILD_TYPE=release \
&& nice make -j3 && make install
fi
}
Checking logs
So, updating KDE is now a matter of calling kdeup and kdemake. The next thing to do is to create a watching mechanism (to put it in the command watch plasmoid for example).
The first script is outputting what is currently being built – something like this:
/opt/kde4trunk/log/KDE_support.build : [ 49%] Built target phonon
The code for this bash script is:
#!/bin/bash
WHATFILE=`ls -t1 /opt/kde4trunk/log/*.build | head -n 1`
WHAT=`grep '%' $WHATFILE | tail -n 1`
echo $WHATFILE ":" $WHAT
That’s all for today.
There were two main problems with the Lancelot Part applet.
The second problem was that a lot of users thought that Lancelot Part does nothing (aka doesn’t work) because when you add it by using the widgets browser, it is just an empty applet. (nobody really bothers reading the instructions these days).
I’m currently having some problems wording a couple of things and I would appreciate any help you can give.
