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

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Also the website given in -system-zlib option is outdated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