cmake note wrt version to be used

Current status of setting up the CI system

This page shall describe what has to be done to get a KDE/CI system up and running on OSX. Partially this is achieved by using a few ports from MacPorts.

Start with a fresh Mavericks/MacPorts install

Currently using the official MacPorts version 2.3.1 is recommended. To be on the safe side make sure your disk has about 60G space in total.

However, currently a Mavericks 10.9.4 KDE/CI system on an i7-iMac uses something like this:

$ df -h /
Filesystem      Size  Used Avail Use% Mounted on
/dev/disk0s2      64G   40G   25G  62% /

that is after all frameworks have been built and installed as shown further down.

Getting a MacPorts-compatible bash environment

Install ports for MacPorts' bash

$ sudo port install bash bash-completion

and set up the bash environment for MacPorts use regarding search paths (PATH, MANPATH)

Apple developer tools

Install

  • Xcode from AppStore (and agree actively to the developer license agreement)
  • developer command line tools
    $ xcode-select --install
    

Tools already present on OSX

Some tools are already installed on OSX due to Xcode (like git, svn, ssh, rsync, make, clang etc.) they don't need to be installed via MacPorts for now. Should a more up-to-date version of any one of these be necessary for the CI system it could be added later.

Some more software supplied by MacPorts

Install ports needed for the CI scripts as well as KF5:

$ # Ports for CI:
$ sudo port install gnutar py27-lxml bazaar mercurial wget automake autoconf cppcheck lcov
$
$ # Ports for KF5:
$ sudo port install shared-mime-info docbook-xml docbook-xsl giflib boost

Basic setup of CI system

In order to start building up a build slave for KDE's Jenkins-based CI system it is in principle needed to clone websites/build-kde-org, BUT further down it will become clear, that it is a good idea to track all changes to be made for websites/build-kde-org in a dedicated branch. That is why the dedicated repository clone "mp-osx-ci" has been introduced which has the branch 'mp-osx-ci' containing all changes needed for a CI system on OSX.

Create some folders, clone and update CI system (assuming a user "kdeci" with its home directory "/Users/kdeci"):

$ cd
$ mkdir -p WC/KDECI-build;
$ cd WC
$ git clone git://anongit.kde.org/clones/websites/build-kde-org/kaning/mp-osx-ci.git
$ cd build-kde-org
$ git checkout mp-osx-ci
$ ./update-setup.sh                    # Ignore 404 occurring due to error cloning ECMA262 by hg

The update shell script created a folder ~/scripts in which all subsequent commands will have to be executed.

(BTW, if you were checking out the original repository from git://anongit.kde.org/websites/build-kde-org you'd have to check out the "production" branch.)

Note: All configuration settings listed below should already be present in the configuration set up in branch 'mp-osx-ci'.

1st step: Qt5 build

Prepare environment for Qt5 build

Install additional ports specific for Qt5 as well as KF5, set correct path to KDE-install directory in config/build/darwin-mavericks.cfg:

$ sudo port install zlib openssl dbus jpeg tiff libmng libpng mysql55 pkgconfig sqlite2
$ sudo port uninstall cmake            # Remove MacPorts' cmake (which came into the system as build-dependency for mysql55)
$ cd ~/scripts
$ cat config/build/darwin-mavericks.cfg
[DEFAULT]
scriptsLocation=/Users/kdeci/scripts
opSys=darwin
architecture=mavericks
compiler=clang

[General]
installPrefix=/opt/kde/install/%(opSys)s/%(architecture)s/%(compiler)s/
$ python2.7 tools/prepare-environment.py --project qt5 --branchGroup kf5-qt5 --platform darwin-mavericks --sources ~/WC/KDECI-build/qt5
...
$

BTW, it could be important to also install freetype for Qt5, but it hasn't been clarified yet whether it should be there or not.

Set up build environment for Qt5

It is recommended to build the debug version. Also make sure that all libs can be found by adding search paths and avoid inclusion of MacPorts' glib2:

$ cd ~/scripts; cat config/build/qt5/darwin-mavericks.cfg
[Build]
configureCommand=%(configureExecutable)s -debug -separate-debug-info -system-zlib -system-libpng -system-libjpeg -system-sqlite -dbus -plugin-sql-mysql -nomake examples -confirm-license -opensource -prefix {instPrefix} -no-framework -v -I/opt/local/include -L/opt/local/lib -no-glib

Include MySQL's binary path into PATH e.g. in .macports/profile (assuming /opt/local as MacPort's prefix):

export PATH=/opt/local/lib/mysql55/bin:$PATH

Set up SSH for rsync access to build host, then start building Qt5:

$ cat ~/.ssh/config 
Host build.kde.org
   Port 2022
$ ssh-keygen -C YOUR@EMAIL.ADDRESS       # <-- send your public SSH key to Ben Cooksley in order to get access to the build server
$ python2.7 tools/perform-build.py --project qt5 --branchGroup kf5-qt5 --platform darwin-mavericks --sources ~/WC/KDECI-build/qt5
...

Installation of cmake

Cmake needs a manual checkout of its sources:

$ python2.7 tools/prepare-environment.py --project cmake --branchGroup kf5-qt5 --platform darwin-mavericks --sources ~/WC/KDECI-build/cmake
...
$ git clone git://cmake.org/cmake.git ~/WC/KDECI-build/cmake
$ python2.7 tools/perform-build.py --project cmake --branchGroup kf5-qt5 --platform darwin-mavericks --sources ~/WC/KDECI-build/cmake
...

Note: Currently it seems to be necessary to NOT to install the latest git version on OSX, as this causes build problems for framework kcoreaddons later on. The version 3.0.x from June 3rd (0ee116b7eb1e65d7e7ae6c13628c57eec038b53d) is working fine so far.

Keeping build environment up-to-date

For KF5 one has to modify the configuration settings by commenting out the kauth dependency on polkit-qt-1, since that dependency is only needed on Linux:

$ cd ~/scripts
$ ./update-setup.sh
$ vi config/base/kf5-qt5 
$ grep kauth config/base/kf5-qt5
#frameworks/kauth: kdesupport/polkit-qt-1
$

Problems appeared for some frameworks since kconfig_compiler_kf5.app doesn't yet get installed on OSX (the build scripts error out with "/Applications/KDE/kconfig_compiler_kf5.app/Contents/MacOS/kconfig_compiler_kf5 as location is wrong"). This can be fixed for now introducing a temporary configuration file for kconfig:

$ cat ~/scripts/config/build/kconfig/darwin-mavericks.cfg 
[DEFAULT]
configureExtraArgs=-DCMAKE_INSTALL_BUNDLEDIR="lib/libexec/kf5"

which makes sure that the application bundle gets installed below PREFIX/lib/libexec/.

In order to always have the latest KDE/CI running it makes sense to temporally stash away the changes made locally and upgrade via git

$ # Check what has changed locally:
$ git diff

Note 1: It may be that the DATA_INSTALL_DIR setting is actually not needed!

Note 2: DYLD_LIBRARY_PATH has only temporally been added due to wrong linking of phonon (e.g. for kate and kwrite).

Installation of other projects and KDE frameworks

The various frameworks have to be handled by replacing "PROJECT" with the framework's project name:

$ python2.7 tools/prepare-environment.py --project PROJECT --branchGroup kf5-qt5 --platform darwin-mavericks --sources ~/WC/KDECI-build/PROJECT
...
$ (cd ~/WC/KDECI-build/PROJECT; git checkout jenkins)
...
$ python2.7 tools/perform-build.py --project PROJECT --branchGroup kf5-qt5 --platform darwin-mavericks --sources ~/WC/KDECI-build/PROJECT
...

or alternatively by using scripts from our MacPorts/KDE git repository

$ ./prepare.sh PROJECT
...
$ ./build.sh PROJECT
...

where prepare.sh takes care of creating the build directory if it is not yet existing as well as checks out the branch 'jenkins'. This is only needed when building a project manually, otherwise it gets one by the jenkins slave. Alternatively one can combine both of these steps using:

$ ./install.sh PROJECT

All frameworks of a specific tier can be build as a whole using

$ # This builds all frameworks of tier 1
$ ./tier-install.sh 1
...
$ # This builds all frameworks of tier 2, but forces rebuilding every project regardless of
$ # whether git pulled in changes or not (useful when e.g. qt5 or cmake was updated)
$ ./tier-install.sh 2 rebuild
...

In order to be able to build KF5 frameworks of tier 3 it is - as a temporary workaround - necessary to copy kdoctools' and kdelibs4support's files from their install directories to where framework builds can find them (i.e. below "/Library/Application Support"), which is already implemented in build.sh.

All frameworks of all tiers can be build easily using

$ ./all-tiers-install.sh

which will iterate trough tiers 0 up to 5, with tiers 0 and 5 being just "virtual" tiers - which were introduced to more easily build some projects.

KF5 builds have been successfully done so far for these projects:

Additional dependencies (referred to as "Tier 0"):
 - extra-cmake-modules
 - phonon

 - kf5umbrella

Curly brackets in the above lists mark frameworks marked on KDE's official API page as having problems on MacOSX, since plasma won't be running for now.

Having the very compact Gentoo's Project:KDE/Frameworks wiki page around turned out to be very helpful while building the above KDE frameworks manually. More info is found on KDE's official API page and the above lists have been aligned with it: nice dependency graphs for every framework can be found there by clicking the "Dependencies" link on each frameworks page, some more (overview) graphs are here.

As of July 5th 2014 all KF5 frameworks build successfully. {NOTE: Still using the above workaround for the CI system!}

Notes concerning some files installed by the frameworks

Installs into "/Library/Application Support"

These folders should be copied into the MacPorts/KDE-CI system's "/Library/Application Support" directory (as it was done for as a temporary work-around for kdoctools above):

$ cd ~/WC/KDECI-builds; find . -type d -wholename "./*/local-inst/opt/kde/*/Library/Application Support/*" | egrep "/kf5$"

Problematic installs into "/Library/Application Support"

As an example the following folders for project ktexteditor do not reside below a kf5 sub-directory of "/Library/Application Support" which seems to indicate that there is a problem in the corresponding CMake files of that framework:

$  cd ~/WC/KDECI-builds; find . -type d -wholename "./*/local-inst/opt/kde/*/Library/Application Support/*" | grep -v "/kf5/" | egrep -v "/kf5$"
./ktexteditor/local-inst/opt/kde/install/darwin/mavericks/clang/kf5-qt5/frameworks/ktexteditor/inst/Library/Application Support/katepart

./ktexteditor/local-inst/opt/kde/install/darwin/mavericks/clang/kf5-qt5/frameworks/ktexteditor/inst/Library/Application Support/katepart5/syntax

Formerly there was a similar issue for the khtml framework:

./khtml/local-inst/opt/kde/install/darwin/mavericks/clang/kf5-qt5/frameworks/khtml/inst/Library/Application Support/khtml

but this has been already moved to another location, due to a change of the kxmlgui framework itself.

Installs into "/Applications/KF5"

These are all application packages which might have to be copied into /Applications/KF5 on the KDE/CI system:

$ cd ~/WC/KDECI-builds; find . -type d -wholename "./*/local-inst/opt/kde/*/frameworks/*/Applications/KF5/*.app" 
./kactivities/local-inst/opt/kde/install/darwin/mavericks/clang/kf5-qt5/frameworks/kactivities/inst/Applications/KF5/kactivitymanagerd.app

Installs NOT into "/Applications/KF5"

These are all application packages which MIGHT NOT have to be copied into /Applications/KF5 on the KDE/CI system:

$ cd ~/WC/KDECI-builds; find . -type d -wholename "./*/local-inst/opt/kde/*/frameworks/*.app" | grep -v "Applications/KF5"

kdesupport-svn - a prerequisite for further projects

In order to be able to build some KDE applications it is necessary to install kdesupport-svn, which is not automatically handled by the prepare script. Therefore one needs to check out its sources using Subversion and install it like this:

$ mkdir ~/WC/KDECI-builds/kdesupport-svn
$ svn checkout svn://anonsvn.kde.org/home/kde/trunk/kdesupport ~/WC/KDECI-builds/kdesupport-svn
$ ./build.sh kdesupport-svn

KF5 software beyond the basic frameworks

Since the basic set of frameworks is now ready for use on OSX one can go ahead and start building other software depending on KF5. Important projects are e.g. KDevelop, KMyMoney, but also KDE-EDU applications on their route to KF5 can serve as good test cases. This is referred to as "Tier 5":

Done:
 - kde-cli-tools
 - khelpcenter ($)
 - kate (-+)
 - libkomparediff2
 - kfilemetadata
 - kdevplatform
 - kinfocenter (+)
 - kdevelop (+)
 - okteta  ($)
 - qca
 - konversation ($)
 - konsole ($)
 - akonadi
 - alkimia (needs port gmp installed)
 - kmymoney (+1)
 - kde-baseapps (2)

KDE edu:
 - libkdeedu (§)
 - libkeduvocdocument
 - analitza
 - kalgebra (!)
 - step (+)
 - kgeography (+)
 - kig (?)
 - kanagram (?)

Planned:
 - parley (3)
 - kstars (4)
 - artikulate (5)
 - kiten (6)
 - prison (needs ports qrencode and "libdmtx -x11" [which pulls also these in: ImageMagick djvulibre fftw-3 fontconfig freetype ghostscript jbig2dec lcms2 urw-fonts webp]) 
 - kdepimlibs (7)

Unneeded on OSX (tried just for the fun of it):
 - libkscreen (a)
 - kde-runtime (a,b)
 - ktp-common-internals (c)
 - libksysguard (d)
 - khotkeys (e)
 - kmenuedit (e)
 - milou (f)
 - powerdevil (f)
 - baloo (g)
 - xapian

Legend:

($) does not start because it can't find dbus atm, i.e. exits gracefully
(-) crashes on startup (b.k.o. issue 337140) and needs DYLD_LIBRARY_PATH set for phonon
(+) crashes on startup due to missing dbus
(§) according to PovAddictW not very much useful in there anymore these days (kalgebra doesn't need it)
(!) application can actually be executed successfully
(?) starting application still untested

(1) kmymoney has some (temporally) optional frameworks
(2) needs patch regarding docbook DTD
(3) can't find libkdeedu
(4) Eigen3 needed
(5) Qt5GStreamer needed
(6) branch frameworks still missing
(7) needs prison

(a) FWs require Qt5X11Extras, although it is switched off in global configuration using -DCMAKE_DISABLE_FIND_PACKAGE_X11=ON
(b) kde-runtime is not needed, since its functionality is currently getting ported into other KF5 FWs step by step
(c) ktp-common-internals requires TelepathyQt5
(d) libksysguard is broken (see also this)
(e) need libksysguard
(f) needs baloo
(g) needs xapian
