Hi,<br><br>i had compiled qgis for my LInux PC and its working fine.now i need to develop a standalone qgis application. i followed teh steps in the website:<br><br><a href="http://blog.qgis.org/?q=node/10">http://blog.qgis.org/?q=node/10</a>.<br>
<br><br>but i could not compile it successfully. the following are the errore:<br>saravanan@spa:~/workspace/QGIS_programming/mapDisplay> make<br>g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I../../../userQtopia/install_path/mkspecs/default -I. -I../../../userQtopia/install_path/include/QtCore -I../../../userQtopia/install_path/include/QtCore -I../../../userQtopia/install_path/include/QtGui -I../../../userQtopia/install_path/include/QtGui -I../../../userQtopia/install_path/include -I/home/saravanan/QGIS/qgis_0.9.1/src/app -I/home/saravanan/QGIS/qgis_0.9.1/src/core -I/home/saravanan/QGIS/qgis_0.9.1/src/gui -I. -I. -o main.o main.cpp<br>
