Explanation of the entire process of QT installation (1)

QT InstallationThe whole process is the content to be introduced in this article, mainly to understand and learnQTThis article is mainly to learnQT InstallationThe process and implementation of specific content are described in detail in this article.

I,QtSource code compilation

1. Compile the touch screen software tslib

Decompress tslib-1.4.tar.gz

 
 

  
  
Tar-zxvftslib-1.4.tar.gz-C/usr/local  
  
  
cdtslib  
  
  
apt-getinstalllibtool  
  
  
apt-getinstallautoconf  
  
  
apt-getinstallg++ 
 
 

Under the tslib directory

 
 

  
  
./Autogen. sh
  
  
CC = arm-linux-gcc
  
  
#### Echo "ac_cv_func_malloc_0_nonnull = yes"> arm-linux.cache // ### it indicates that the comments are removed. The third sentence is the combination of the first two sentences.
  
  
####./Configure -- prefix =/opt/ts/-- host = arm-linux -- cache-file = arm-linux.cache
  
  
./Configure -- prefix =/opt/ts/-- host = arm-linuxac_cv_func_malloc_0_nonnull = yes
 
 

Open tests/ts_calibrate.c, modify two open statements, and add the third parameter 0 // atline227229

 
 

  
  
make  
  
  
makeinstall 
 
 

2. Install qt-X11

 
 

  
  
apt-getinstalllibX11-devlibXext-devlibXtst-dev  
  
  
apt-getinstallxorg-dev 
 
 

Decompress tarzxvfqt-everywhere-opensource-src-4.6.3.tar.gz-C/usr/local/

 
 

  
  
mvqt-everywhere-opensource-src-4.6.3qt-everywhere-opensource-src-4.6.3-x11  
  
  
./configure-nomakeexamples-nomakedemos  
  
  
make&&makeinstall 
 
 

In this process, you will be asked to select commercial or open version =, and input o

Then, ask if you want to accept license = and enter yes.

 
 

  
  
make&&makeinstall 
 
 

// What should I do in about three hours?

3. Install qt-x86

 
 

  
  
#tarxzvfqt-everywhere-opensource-src-4.6.3.tar.gz-C/usr/local  
  
  
#mvqt-everywhere-opensource-src-4.6.3qt-everywhere-opensource-src-4.6.3-x86  
  
  
#cdqt-everywhere-opensource-src-4.6.3-x86  
  
  
#./configure-prefix/usr/local/Trolltech/Qt-4.6.3-x86-nomakeexamples-nomakedemos  
  
  
-nomakedocs-nomaketools-embeddedx86-qvfb  
  
  
#make&&makeinstall 
 
 

4. Install qt -- arm

 
 

  
  
./configure-prefix/usr/local/Trolltech/Qt-4.6.3-arm-release-shared-fast-xplatformqws/linux  
  
  
-arm-g++-embeddedarm-depths16-no-qvfb-no-qt3support-qt-sql-sqlite-qt  
  
  
-zlib-qt-libpng-qt-freetype-qt-mouse-tslib-no-mouse-pc-no-mouse-linuxtp  
  
  
-nomakeexamples-nomakedemos-nomakedocs-nomaketools-I/opt/ts/include-L/opt/ts/lib 
 
 

Incorrect. Use the following

 
 

  
  
./configure\  
  
  
-prefix/usr/local/Trolltech/Qt-4.6.3-arm\  
  
  
-release-shared-fast\  
  
  
-xplatformqws/linux-arm-g++-embeddedarm\  
  
  
-depths16-no-qvfb\  
  
  
-no-qt3support-qt-sql-sqlite-qt-zlib-qt-libpng-qt-freetype\  
  
  
-qt-mouse-tslib-no-mouse-pc-no-mouse-linuxtp\  
  
  
-nomakeexamples-nomakedemos-nomakedocs-nomaketools\  
  
  
-I/opt/ts/include-L/opt/ts/lib 
 
 

After the configure command is executed, You need to modify three files:

 
 

  
  
cdqt-embeded-opensource-src-4.6.3-arm 
 
 

1) lines/src/3 rdparty/freetype/include/freetype/config/ftconfig. h330 under this directory

 
 

  
  
"Orr % 0, % 0, % 2, lsl #16 \ n \ t"/* % 0 | = % 2 <16 */
  
  
// Original: "orr % 0, % 2, lsl #16 \ n \ t"
 
 

2)/src/3 rdparty/webkit/WebCore/Makefile

Lines 14 and 15 Add-d1_arm_arch_4t _ (CFLAGS/CXXFLAGS) before-fPIC $ (DEFINES), respectively)

3)/src/script/Makefile

Lines 14 and 15-d1_arm_arch_4t _ (same as above)

 
 

  
  
make&&makeinstall 
 
 

Ii. Establish the environment Trolltech)

1. Set the environment variable Qt-4.6.3

Go to the/usr/local/Trolltech/Qt-4.6.3 directory

Visetenv. sh or sudogeditsetenv. sh

Add

 
 

  
  
PATH=/usr/local/Trolltech/Qt-4.6.3/bin:$PATH  
  
  
LD_LIBRARY_PATH=/usr/local/Trolltech/Qt-4.6.3/lib:$LD_LIBRARY_PATH 
 
 

Save and exit

 
 

  
  
chmod777setenv.sh 
 
 

2. Set the environment variable Qt-4.6.3-x86

Go to the/usr/local/Trolltech/Qt-4.6.3-x86 directory

Visetenv. sh or sudogeditsetenv. sh

Add

 
 

  
  
QTEDIR=/usr/local/Trolltech/Qt-4.6.3-x86  
  
  
PATH=/usr/local/Trolltech/Qt-4.6.3-x86/bin:$PATH  
  
  
LD_LIBRARY_PATH=/usr/local/Trolltech/Qt-4.6.3-x86/lib:$LD_LIBRARY_PATH 
 
 

Save and exit

 
 

  
  
chmod777setenv.sh 
 
 

3. Set the environment variable Qt-4.6.3-arm

Go to the/usr/local/Trolltech/Qt-4.6.3-arm directory

Visetenv. sh or sudogeditsetenv. sh

Add

 
 

  
  
QTEDIR=/usr/local/Trolltech/Qt-4.6.3-arm  
  
  
PATH=/usr/local/Trolltech/Qt-4.6.3-arm/bin:$PATH  
  
  
LD_LIBRARY_PATH=/usr/local/Trolltech/Qt-4.6.3-arm/lib:$LD_LIBRARY_PATH 
 
 

Save and exit

 
 

  
  
chmod777setenv.sh 
 
 

3. Compile qvfb

 
 

  
  
cdqt-everywhere-opensource-4.6.3-x11/tools/qvfb  
  
  
#####/usr/local/qt-everywhere-opensource-src-4.6.3-x11/tools/qvfb  
  
  
make 
 
 

-- Will generate qvfb in qt-everywhere-opensource-4.6.3-x11/bin,

We copy it to/usr/local/Trolltech/Qt-4.6.3-x86/bin

 
 

  
  
cpqvfb/usr/local/Trolltech/Qt-4.6.3-x86/bin 
 
 

Run the test ()

Run the setenv. sh script file under x86. The upper-case S in sourcesetenv. shword is incorrect.) Enter qvfb in the command line and run it in the background)

For the Qtcreator project file qmake file name. pro, then make generates the executable file

 
 

  
  
./Executable file-qws
  
  
The sample file can be found in the qt-everywhere-opensource-4.6.3-x86/examples or demos)
 
 

4. Install QTCreator

 
 

  
  
Chmod777qt-sdk-linux-x86-opensource_2010.02.bin
  
  
Cpqt-sdk-linux-x86-opensource_2010.02.bin/opt
  
  
./Qt-sdk-linux-x86-opensource_2010.02.bin default installation
 
 

6. In ubuntuInstallThe NFS service is convenient when developing the kernel and file system. You can directly use NFS to start the kernel and file system. The installation is as follows:

1. Installation

# Apt-getinstallnfs-kernel-server

2. Enable the NFS port

 
 

  
  
#netstat-tl 
 
 

If the NFS port is in the LISTEN status

3. Configure the NFS server

 
 

  
  
#vim/etc/exports 
 
 

Add:/work * (rw, sync, no_root_squash) to the last line, where:/work is the shared directory, * is accessible from any IP address, and no_root_squash indicates that any user can access

4. Restart the NFS service.

 
 

  
  
#/etc/init.d/nfs-kernel-serverrestart 
 
 

5. view the current working status of the NFS server

#/Etc/init. d/nfs-kernel-serverstatus

If running is displayed, it works normally.
