想要實現並測試touch 所以把qt 跟tslib都裝上
不過 .......問題來了..編qt 不加 example 跟 demos 都沒問題
但加上去就連結錯誤..
以下是經過....


問題; 編譯qt自帶的example 出現連結錯誤

出現上述錯誤

網路上查找相關解答
1.有人說 沒清乾淨
make confclean

殘念....1....

2.沒裝zlib
sudo apt-get zlib1g zlib1g-dev
 
殘念....12....

3.組態錯誤
 First I noticed ./configure -help states -system-zlib as the default
configuration option (*). Though when I ran

./configure
It states:
zlib support ........ yes

I guess this means -qt-zlib is the default (not like stated in -help) since

./configure -system-zlib
states that:
zlib support ........ system


Also the website given in -system-zlib option is outdated

I tried ./configure with both these options
    -qt-zlib ........... Use the zlib bundled with Qt.
 *  -system-zlib ....... Use zlib from the operating system.
                        See http://www.info-zip.org/pub/infozip/zlib

殘念....3....

4.加上 -lz

最後這各 我在 qmake.conf 裡面加上 -lz 就編過了 ..
如果你有加 tslib 也是在這裡加上 -lts

/qt/qt-everywhere-opensource-src-4.7.3/mkspecs/qws/linux-arm-gnueabi-g++/qmake.conf


QMAKE_CC                = arm-none-linux-gnueabi-gcc
QMAKE_CXX               = arm-none-linux-gnueabi-g++
QMAKE_LINK              = arm-none-linux-gnueabi-g++
QMAKE_LINK_SHLIB        = arm-none-linux-gnueabi-g++
==>
QMAKE_CC                = arm-none-linux-gnueabi-gcc -lts
QMAKE_CXX               = arm-none-linux-gnueabi-g++ -lts
QMAKE_LINK              = arm-none-linux-gnueabi-g++ -lts -lz
QMAKE_LINK_SHLIB        = arm-none-linux-gnueabi-g++ -lts -lz



另外 正常編譯qt
可以不用把example 一起編進去
configure 時 加上 -nomake examples 跟 -nomake demos 就可以

如下;
    ./configure -prefix $QTE_PATH \
            -embedded arm \
            -xplatform qws/linux-arm-gnueabi-g++ \
            -little-endian \
            -no-mouse-pc \
            -no-mouse-linuxtp \
            -no-mouse-linuxinput \
            -no-mouse-qvfb \
            -no-mouse-qnx \
            -qt-kbd-linuxinput \
            -no-kbd-tty \
            -no-kbd-qvfb \
            -no-kbd-qnx \
            -opensource \
            -no-qt3support \
            -no-javascript-jit \
            -no-webkit \
            -release \
            -DQT_QWS_CLIENTBLIT  \
            -DQT_NO_QWS_CURSOR \
            -reduce-relocations \
            -no-scripttools \
            -fast \
            -continue \
            -confirm-license \
            -nomake demos \
            -nomake examples \
            -nomake docs \
            -qt-mouse-tslib -L /opt/tslib/lib -I /opt/tslib/include
            
            
若你想要單獨的example就在example目錄下面自己編就可以

對了 部分example 與 demo 裡面的程式 可能沒touch 功能..要注意一下囉
