Install and establish a QT desktop running environment

Install and establish the QT desktop running environment-general Linux technology-Linux programming and kernel information. The following is a detailed description. After a whole day, I finally set up the QT desktop running environment. Now I want to sort out the problems I encountered in this process as follows:

Question 1:
In the process of compiling Qt/Embedded, the first step is to establish QT2.3.2, that is, Bulid Qt2.3.2. After make, an error occurs.

Error: cannot convert 'qvaluelistiterator 'To 'const char *' for argument'

Solution: cd/root/2410sQt/host/qt-2.3.2/include
Gedit qvaluestack. h

In row 57 of the file: remove (this-> fromLast (); change to this-> remove (this-> fromLast ());

Problem 2: During Qt/Embedded compilation, after make is performed in Bulid Qvfb in step 2, an error is prompted.

Tmake error: template file tamke. config not founded.

Cause Description: The environment variable settings are incorrect. As a result, you cannot connect to tamke. config under $ TMAKEPATH/lib/linux-g ++.

Solution: 1) open a new terminal, gedit. bashrc
2) In. bashrc, re-enter the environment variable
Export PATH =/arm2410s/linux/gui/Qt/tools/usr/local/arm/3.4.1/bin: $ PATH
Export TMAKEPATH =/root/2410sQt/host/tmake-1.13/lib/linux-g ++
Export QTDIR =/root/2410sQt/host/qt-2.3.2
Export QTEDIR =/root/2410sQt/host/qt-2.3.10
Export LD_LIBRARY_PATH = $ QTDIR/lib: LD_LIBRARY_PATH
3) source. bashrc

Question 3: After you input make to compile the file, a prompt is displayed.
Make: Nothing to be done for "all"
Solution: first enter make clean
Enter make

Problem 4: In the process of compiling Qt/Embedded, in step 3 Bulid Qt/Embedded, the following problems occur after make compilation.

Error: 'qwsinputmethod' has not been decleared.

Solution:
Cd $ QTDIR/src/kernal
Gedit qwindowsystem_qws.h
Add the following files at the beginning:
Class QWSInputMethod;
Class QWSGestureMethod;

Question 5: when compiling Qt/Embedded, check the running result in Step 4: After Entering qvfb-width 640-height-480 &, qvfb: error while loading shared libraries: libqt. so.2: cannot open shared object file: No such file or directory

Error cause: the path libqt. so.2 is not found, and libqt. so.2 is in the QT2DIR directory. This indicates that the path is set incorrectly.

Solution: LD_LIBRARY_PATH is incorrect. Input echo $ QT2DIR.
Echo $ QTEDIR echo $ LD_LIBRARY_PATH to ensure that each returned path exists and is valid.

Question 6: run your own program in the created environment and enter
$ TMAKEDIR/bin/progen-t app. t-o hello. pro, the problem cannot be found by progen, indicating that the path setting of TMAKEDIR is incorrect. The method is the same as above.
