Information about porting Opie to MacOS-X (eilers) ================================================== Credits: -------- Special thanks to Andreas Junghans (webmaster@lucid-cake.net) providing patches for qt-X11 (2.3.2), QT/E (2.3.5) and qtopia (1.6.1). Without them, I wasn't able to provide the port for OPIE to MacOS-X that fast.. Thanks to Juergen Graf to debug this very generic README ! Status: ------- Aim of this work is to provide a development platform for Apple-Users! Please do not expect that you could create a productive Opie system for the Mac with it !! The basic system works quite well. But a lot of applications and plugins, which are platform specific, need some work to be compileable. What is ready: libqpe libopie1 libopie2 pim-applications (addressbook, todolist, datebook, today) A lot of applications and plugins which are not platform specific. ToDO: ----- There are some functions in the sourcecode which are not yet ported to Mac. If the MacOS environment should be used for real productive work, the following functions must be implemented correctly: libopie/pim/otimezone.cpp: Accessing of "setenv(...)" on Mac caused bus-errors. Workaround/Fix: Unknown Current-State: setenv() was just commented out. Thus the related functions may behave wrong! How to compile Opie for MacOS-X: ------------------------------- Before compiling for MacOS-X, you need the following: 1. X11-Server+X11SDK (Provided by Apple) 2. QT-2.3.2 for X11 (Provided by Trolltech) 3. QT/E-2.3.7 (Provided by Trolltech) 4. Patches for QT-2.3.2 for MacOSX (take the one in this directory !) 5. Patches for QT/E-2.3.7 for MacOSX (take the one, provided in $OPIEDIR/qt) The Patch for QT-2.3.2 is provided in this directory and is called "qt232-X11.patch". The Patch for QT/E for Opie, including all other opie-patches is available in the qt-directory ($OPIEDIR/qt) and is called "qte237-all-macosx.patch". Please read further, how to compile the stuff. HOWTO COMPILE: ------------- Compile QT-2.3.2: Go to into the basic directory of qt-2.3.2 and enter export QTDIR=`pwd` export DYLD_LIBRARY_PATH=$QTDIR/lib ./configure -no-xft -platform darwin-g++ make After compiling successful (I hope) you need qvfb: cd tools/qvfb make Compile QT/E-2.3.7: Got to into the basic directory of qt-2.3.2 and enter export QTDIR=`pwd` export QPEDIR=$QTDIR export DYLD_LIBRARY_PATH=$QTDIR/lib ./configure -platform darwin-generic-g++ -qconfig qpe -qvfb -depths 4,8,16,32 make Now create a link for the uic of qt-2.3.2 into the bin-directory of qt/e 2.3.7 ! Otherwise OPIE will fail to compile ! Compile OPIE (Please don't forget to read the following "Known Bugs" section!): Set your environment (You may use the script "set_vars.sh" to set your variables successfully ! BUT: You have to customize this script for YOUR needs !!) Go into the basic directory of Opie make menuconfig" set "Build Parameters"->"Target Machine"->"Mac OS X (DARWIN)" to activate the platform specific changes. save and exit the menuconfig app make (ATTENTION: See Known Bugs below!!) You will see that a lot of applications and plugins/applets will not compile successfully, due to the fact that they are not ported to this platform. You may disable them to be able to compile the rest. Remember: A lot of configuration-settings are not tested and might fail to compile. If you want to avoid misconfigurations, you may want to start with the config-file in this directory. Just copy "config_macosx" to $OPIEDIR/.config to get a working configuration to start with. (The missing apps/plugins will be ported on demand.) Known Bugs (compilation problems): ----------- The Apple-Linker does not load indirect linked libraries automatically ( if somebody has a solution here, please inform me !!), therefore I had to add "-lopiedb2" and "-lqpe" for applications/libraries who used libraries which are linked against them. A goot solution would be to add it in the project files of these application, but this would influence the linux-platform as well... :( As a first (but stupid) solution, I added this linker parameter to the global "include.pro" which adds them for everything.. Yes, also for libqpe etc.. Therefore this project will not compile out of the box. You have to compile in a two-pass way: Pass 1: Find the line "LIBS += -lopiedb2 -lqpe" or "LIBS += -lqpe" and the line "LIBS += -lopiecore2" in the file include.pro and comment them out (put a "#" in front of them) Do a "make -k" to compile what is already compileable (some will not compile) Pass 2: Remove the comments from Pass1 and do a "make". The rest should compile successfully. I know, this is a silly solution ! But I don't have anything better without influence the Linux build process too much .. I would be happy, if somebody could help me here ! SPECIAL INFORMATION FOR USERS OF PANTHER ---------------------------------------- I had a lot of problems compiling qt-2.3.2 and QT/E-2.3.7 on Panther. The new release of the X-Server causes a lot of trouble.. To compile QT-2.3.2 successfully, you have to disable support of freetype fonts and you have to use the patch in this directory, otherwise your wont't be able to compile ! Use the param "-no-xft" for the configure script to disable this function ! Information for Developers: --------------------------- 1. Platform specific code should be surrounded by #ifdef Q_OS_MACX MACOS-X CODE #else OTHER-CODE #endif 2. The Plugin-Handling by MacOS-X is different than it is by Linux. On linux-systems, shared libraries are not different to dynamic loaded libraries (aka plugins). They just are different whether they are loaded automatically at startup or manually by any application. On MacOS-X, the plugins are loaded by a special mechanism and must be in a special binary format. Therefore you have to add the term "plugin" to the CONFIG-clause, as for instance: TEMPLATE=lib CONFIG += qt plugin release If you don't add "plugin" you will get a shared library which is not loadable (Error-Code: NSObjectFileImageInappropriateFile (2))!
