Tag Archives: Linux


这个VPS当时安装的是Ubuntu 15.04,非LTS。最近发现很多软件没法装最新版本。想升级吧,系统提示的do-release-upgrade还不行。搜了搜,发现得走这样的路径:15.04->15.10->16.04 LTS。

然后发现系统提示php的包不需要了,就删掉了… 然后我的wordpress就起不来了。继续搜,原来出了php7。



Distributed Compilation the build of Qt

Qt is a huge project, especially like the module, QtWebKit. If you happen to be in a computer farm, it is very useful to use distributed complation to speed up the build of Qt.

Here I suggest to use icecream on Linux and Mac OS X, and IncrediBuild on Windows(at least for Microsoft’s Visual Studio compilers). About IncrediBuild, more details perhaps will be updated in the future. See also qtrepotools: publish ibmake.bat, incredibuild xge wrapper for make/buildconsole.

Today, this blog is more about icecc/icecream.



icecream is maintained by the SUSE people. Then there are less issues in OpenSUSE than in Ubuntu. But Ubuntu is more popular one. I just use Ubuntu as example here.

  • Install your compiler, like gcc and clang.
  • Install icecc and icemon(optional). icemon is the monitor of icecream build, better to check it when you setup the enviroments. It’s an GUI application based on Qt 4.8. Note: you need to install 0.9.8~git2012121601-0ubuntu2 and later version for icecc. More details in “icecc” package in Ubuntu.

  • For clang users, if you want to make icecream compiler package, better to do:
    • 13.04: $ sudo ln -s /usr/include/clang/3.2/include /usr/lib/clang/3.2/
    • 12.04: $ sudo ln -s /usr/include/clang /usr/lib/
  • Create compiler package: please do it. Here is the example for 13.04:

  • Enviroment settings before build:

  • Run icecc-scheduler in one of your Ubuntus:
    • Edit /etc/default/icecc, set START_ICECC_SCHEDULER="true".
  • Start icecc service: sudo /etc/init.d/icecc start, icecc-scheduler service also could be started with this. Not suggest to run multiple icecc-scheduler in same network with default values, you could edit /etc/icecc/icecc.conf with more options.
  • Stop icecc service(optional): sudo /etc/init.d/icecc stop

Mac OS X

  • Create a ‘qt’ user. Open System Preferences -> Users & Groups -> “+” under the list of users (you might need to click the lock icon first and type in your password), add a user “qt” with your standard password.
  • Install HomeBrew

  • Install XCode and command line tools.
  • Install icecc and icemon(optional).
  • Create compiler package: please do it. Here is the example for 10.8:

  • Enviroment settings before build: (Note: looks like it doesn’t work well with a compiler package. 2013-06-19)

  • Copy com.github.iceccd.plist into into /Library/LaunchDaemons .
  • sudo chown root /Library/LaunchDaemons/com.github.iceccd.plist
  • Start icecc service: sudo launchctl load /Library/LaunchDaemons/com.github.iceccd.plist
  • Stop icecc service(optional): sudo launchctl unload /Library/LaunchDaemons/com.github.iceccd.plist

Building Qt

Normally just do source ~/.icecc_rc, configure and make.

  • For clang build(both Linux and Mac OS X), please keep in mind to use -no-pch when configure.
  • For Qt4 build, the -arch argument that Qt 4 passes to the compiler confuses icecream. So for now, if you use Qt4, you need to patch your mkspec to not add that (if you build for your local architecture only), eg. in mkspecs/common/gcc-base-macx.conf.(Note: looks like it’s only on Mac OS X, I haven’t tried it yet.)

Known Issues

  • Using icecream currently screws up debug information for all object files that we compiled remotely!(Mac OS X only)


How to run autotests in Qt for Symbian on Linux and Mac?

Here is the official article for it, Installing Qt for the Symbian platform using Linux (experimental).

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

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!

Build Qt 4.7 with Symbian^3 on Linux and Mac OS X

Similar steps as previous blog.

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”.

Build Qt 4.8 with Symbian^3 on Linux and Mac OS X

Build Qt 4.8 with Symbian^3 on Linux and Mac OS X

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
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.




今天还试了试KDE 4.1中的KWin特效,很不错。

Dell Precision 690 & UltraSharp 2407WFP-HC – 2

昨天忘了说了,装这台机器,还遇到了一个 Dell 机器的 bug。就是当我运行 OpenSUSE 10.3 的安装光盘时,在第一个菜单选项处,不可以使用 USB 键盘切换选项,因为默认是进入硬盘启动,所以郁闷了一阵子。

网上搜索了一下,Dell 的一些机型都有同样的问题,需要更新 BIOS。

后来终于有网了,并且使用 KDE 4 Live CD 启动后,上网下载并且更新,还好,Dell 支持在 Linux 下更新,不过在下载的时候也有些问题,我把操作系统换成 Red Hat Linux 选项后,下载文件仍然是 .exe 的。然后就一切 OK 了。

今天把 NVIDIA 的驱动装上了,glxgears 跑得好快呀,1093x FPS。
