2. Qt: 4.8

cd ~/qt
git clone git://gitorious.org/qt/qt.git work
cd work
git checkout -b origin/4.8 4.8
cp -rf mkspecs/unsupported/macx-clang mkspecs/unsupported/macx-checker

Note: a patch for mkspecs/unsupported/macx-checker/qmake.conf: http://pastebin.com/u7mnkhue

3. Clang Static Analyzer: checker-256

cd ~/dev/packages
wget http://clang-analyzer.llvm.org/checker/checker-256.tar.bz2
tar zxvf checker-256.tar.bz2
cd checker-256
rm bin/clang
rm bin/clang++
cd /usr/local/bin
ln -s /Users/liangqi/dev/packages/checker-256/bin/clang-3.0 clang
ln -s /Users/liangqi/dev/packages/checker-256/bin/clang-3.0 clang++

4. Build

cd ~/build
mkdir qt-48-clang
cd qt-48-clang
export PATH=/usr/local/bin:/Users/liangqi/dev/packages/checker-256:$PATH
/Users/liangqi/qt/work/configure -platform unsupported/macx-checker -nokia-developer -no-webkit -no-qt3support -no-declarative -no-xmlpatterns -no-script -no-scripttools -no-phonon -no-multimedia -nomake tools -nomake demos -nomake examples -fast -verbose -no-framework
scan-build make

5. Output

In the end of the output, you will find a command like “scan-build: Run ‘scan-view /var/folders/QB/QBTpJfK+HfqtpmxTOms2nU+++TI/-Tmp-/scan-build-2011-07-20-3′ to examine bug reports.”, do it!

NOTE: the above way doesn’t work with checker-257!

The basic idea is same on Linux and Mac OS X.

1. For phone, you need to install Application TRK

S60 5.0/Symbian^1 – s60_5_0_app_trk_3_2_7.sisx
Symbian^3 – s60_tb_9_2_app_trk_3_2_8.sisx

2. Use usb cable to connect your phone and computer, Linux or Mac OS X. Remember to set to “PC Suite” mode or “Nokia Ovi Suite” mode on your phone. Then launch your Application TRK via “RnD Tools”->”TRK”.

3. About the device name for your phone on computer

For Linux, see more details in Configuring the USB Serial Driver on the Linux System. After that, you will find /dev/ttyUSBx and maybe another /dev/ttyUSBy, better to “sudo chmod 777 /dev/ttyUSB*” for them(some Linux distribution do not give the access to normal users for it, like Ubuntu).

For Mac, you could find sth like /dev/cu.usbmodemfaXx and /dev/cu.usbmodemfaXy.

4. To build runonphone, you need to have libusb installed.

For Linux, just follow that documentation, “sudo apt-get install libusb-dev” should be ok for Debian/Ubuntu.

For Mac, “sudo brew install libusb-compat” works for me.

5. Build runonphone, use the qmake in your desktop Qt.

cd ~/qt/qt/tools/runonphone
/usr/bin/qmake
make

6. Build and run your autotests, please check previous blog for the EPOCROOT and PATH environments settings.

cd qt/qt/tests/auto/qdatetime
~/build/s3_gcce/bin/qmake -spec ~/qt/qt/mkspecs/symbian-gcce -o Makefile ~/qt/qt/tests/auto/qdatetime/qdatetime.pro
make sis
~/qt/qt/tools/runonphone/runonphone -p /dev/cu.usbmodemfa44 –sis ~/qt/qt/tests/auto/qdatetime/qdatetime.sis qdatetime.exe

NOTE: Here the /dev/cu.usbmodemfa44 is the device on Mac for me. And for Linux, the device is sth like /dev/ttyUSB1.

Enjoy it!

Here I will only mention the difference between them:

1. Qt 4.7, please wait a while for the merging of 7c499bcfbf7f9c52b3d6523fea8396bd4ab7252e.

git checkout -b 4.7 origin/4.7

2. You could enable the webkit which is inside of 4.7, then the configure line should be like:

~/qt/qt/configure -developer-build -opensource -confirm-license -xplatform symbian-gcce -webkit -fast -silent -nomake examples -nomake demos -nomake tools -nomake tests -qtlibinfix _liang

And for QtWebKit package:

cd ~/build/s3_gcce/src/3rdparty/webkit/WebCore
make sis
copy ~/build/s3_gcce/lib/QtWebKit_liang.sis toyourphone

For the demo browser application:

cd ~/qt/work/demos/embedded/anomaly
make sis
copy anomaly.sis toyourphone

3. Install the above Qt_liang.sis, QtWebKit_liang.sis, analogclock.sis and anomaly.sis, and enjoy them.

Launch it at “QtExamples”->”analogclock”.
Launch it at “QtDemos”->”anomaly”.

Kudos to Kristian Amlie and Thomas Zander for the “make file build system”.

1. OS:

Linux – mine is 2.6.38-8-generic x86_64
Mac OS X – mine is 10.6.8 64bit

2. Symbian^3

NOTE: Looks like Qt is still not the 1st-priority citizen in the Symbian^3 SDKs world, the reason why I say like that is this task, it means that you cannot use any version of Symbian^3 (public) SDKs to build Qt libraries from source. Details in the comment. Then we use the Symbian^3 PDK 3.0.4 for now. I am not sure how long this mirror service will be available there, you’d better backup those files by yourself.

Symbian^3 PDK 3.0.4

Please download binaries_armv5_lib.7z.zip, binaries_armv5_udeb.7z.zip, binaries_armv5_urel.7z.zip, binaries_epoc.7z.zip, binaries_epoc_sdk.7z.zip, binaries_prebuilt.7z.zip, tools_epoc.7z.zip at least.

cd ~
mkdir -p symbian-sdks/pdk304
cd symbian-sdks/pdk304
7z x abovefiles
export EPOCROOT=~/symbian-sdks/pdk304/ //set env for EPOCROOT

The patch for Symbian^3 PDK 3.0.4 is here.

3. Wine

NOTE: The reason for installing wine is we are using the Symbian tools build on Windows, such as rcomp, makesis and many others.

Linux(Debian/Ubuntu): sudo apt-get install wine1.2
Mac OS X: Install wine 1.1.44, and upgrade it to 1.2

Add wine into path
export PATH=/Applications/Wine.app/Contents/Resources/bin:$PATH //for Mac OS X

4. Compilers:

Linux: RVCT 2.2(need commercial license) or GCCE 4.4.1(Symbian ADT Sourcery G++ Lite 4.4-172 for ARM SymbianOS)
Mac OS X: GCCE 4.4.1(Symbian ADT Sourcery G++ Lite 4.4-172 for ARM SymbianOS), after installed to default path, mv /Applications/CodeSourcery/Sourcery G++ Lite/ /Applications/CodeSourcery/Sourcery_G++_Lite. NOTE: need to remove those spaces in the path of compiler

Add compiler path into PATH:
export PATH=/Applications/CodeSourcery/Sourcery_G++_Lite/bin:$PATH

5. Qt 4.8

NOTE: better to use ea7ed6b27301a4834b1bfe0ad4e6e58462647d3e and later.

cd ~
mkdir qt
git clone -n git://gitorious.org/qt/qt.git qt
cd qt
git checkout -b 4.8 origin/4.8

6. Build it

cd ~
mkdir build
cd build
mkdir s3_gcce // this is for the GCCE case, or s3_armcc for RVCT 2.2 case
cd s3_gcce
~/qt/qt/configure -developer-build -opensource -confirm-license -xplatform symbian-gcce -no-webkit -fast -silent -nomake examples -nomake demos -nomake tools -nomake tests -qtlibinfix _liang // this is for GCCE case, or “-xplatform symbian-armcc” for RVCT 2.2 case
make -j8 // maybe fail at somewhere, then just try “cd src;make -j1″ finish it
cd src/s60installs
make sis
cd ~/build/s3_gcce/lib
cp Qt_liang.sis toyourphone
cd ~/qt/qt/examples/widgets/analogclock
~/build/s3_gcce/bin/qmake
make sis
copy analogclock.sis toyourphone

7. Install your own build Qt libraries and application

Goto “Office”->”File Manager”, manually install Qt_liang.sis and analogclock.sis

8. Run your appliation

Launch it at “QtExamples”->”analogclock”. Enjoy it!

Known issues or other topics:
1. There is still some issue to build qtwebkit which the one inside of qt 4.8 or from qtwebkit git repo directly. If I got solution, I will let you know.
2. Mabye write something about runonphone on Linux and Mac OS X, it is a very good tool to test qt applications.

目前这些测试用例都还在在$QTDIR/tests/auto下：

bic
说明：利用g++的-fdump-class-hierarchy参数生成的类信息数据和VTable数据检查二进制兼容性。对于库来说很重要。gen.sh对已发布的版本生成历史数据，然后调用g++ -fdump-class-hierarchy生成当前版本数据再进行比较。只要是支持g++的平台都可以检测。

compilerwarnings
说明：tst_CompilerWarnings::warnings()中对几种编译器的警告进行了检测。

headers
说明：tst_Headers::licenseCheck()中对所有源文件进行协议检查。tst_Headers::privateSlots()中对所有头文件检查了私有槽必须含有“_q_”。tst_Headers::macros()对所有头文件检查了宏。

symbols
说明：利用nm检查库中函数名和全局变量。tst_Symbols::prefix()中利用nm -g -C -D –format=posix –defined-only对库中的函数名称的前缀进行检查。tst_Symbols::globalObjects()中利用nm -C –format=posix对库中的全局静态对象进行检测，应该是不能有的。

想想自己本科时做的东西，就太没意义了

装上了Snow Leopard和官方发布的Qt 4.7.0 Beta 2和Qt Creator 2.1快照版，想debug进Qt库，竟然不成，咨询了公司内外的Mac开发朋友，原来我遇到了Apple的bug。

DYLD_IMAGE_SUFFIX=_debug makes application crash on Mac OS X – Snow Leopard
DYLD_IMAGE_SUFFIX causing havoc on Mac OS X Snow Leopard

而且变态的Apple自己的bug tracker还是封闭的，只有号码，看不到具体情况。

最后的解决办法是：

cd /usr/lib
sudo mv libSystem.B_debug.dylib libSystem.B_debug.dylib.bak
sudo mv libmx.A_debug.dylib libmx.A_debug.dylib.bak


之前还以为/Developers/SDKs/MacOSX10.6.sdk/usr/lib的有效呢。

BTW，学习了OS X下的ldd就是otool。

其它参考文档：
Technical Note TN2124: Mac OS X Debugging Magic

2010年7月30日注：升级到XCode 3.2.3后，依然崩溃。

Please run this, Start->Carbide.c++ v2.0->Configure environment for WINSCW command line.
And you also need to use Git to get Qt from Qt Git Repo, better to download this version of Git.

Please also make sure the path of our perl(default: C:Perlbin) should be before the perl in git(default: C:Program FilesGitbin) in PATH.

For Host Tools:
For MinGW user, please download MinGW-5.1.4.exe(Note: here the 5.1.4 is the version of installer, the compiler version is 3.4.5.), use it install g++ and make at least. And please add the env for MinGW, C:MinGWbin, at the beginning of the PATH.
For Microsoft Visual C++ Express Edition user, please download the vcsetup.exe and install 2008 with SP1.

For Device:
You need to install RVCT 2.2, we are using “Build 683″. You can use RVCT to build Qt libraries and applications which could running on S60 devices.
You can also install the “CSL Arm Toolchain”, if you forgot it, you can find it in Start->S60 Developer Tools->5th Edition SDK->v1.0->Tools->CSL Toolchain (GCCE) Install. You can use GCCE to build Qt applications with pre-build Qt libraries, and run your Qt applications on devices.

3. Build Qt with S60 5.0 Public SDK

For MinGW user, just open a Windows Command Prompt.
For VC2008EE user, please open Visual Studio 2008 Command Prompt.
