1、移植pjsip

env:fedora14

arm-linuc-gcc:gcc version 4.5.1 (ctng-1.8.1-FA) 

#./configure \

CC=arm-linux-gcc \

CROSS_COMPILE=arm-none-linux-gnueabi- \

--build=i386-linux \

--prefix=/usr/local/pjsip \

--host=arm-none-linux-gnueabi \

--target=arm-none-linux-gnueabi 

#make dep

#make 

#make install

2、将pjsip库加载进QT工程中

将以下库添加到pro文件中

unix:!macx:!symbian: LIBS += -L/usr/local/pjsip/lib/ -lpjsua-arm-none-linux-gnueabi \

-lpjsip-ua-arm-none-linux-gnueabi \

-lpj-arm-none-linux-gnueabi \

-lm \

-luuid \

-lnsl \

-lrt \

-lpthread  \

-lasound

INCLUDEPATH += /usr/local/pjsip/include

DEPENDPATH += /usr/local/pjsip/include

3、编译出错

 from ../QT_PJSIP_VOIP/qt_sip.h:3,

 from ../QT_PJSIP_VOIP/mainwindow.h:6,

 from ../QT_PJSIP_VOIP/main.cpp:2:

/usr/local/pjsip/include/pj/config.h:1161:4: error: #error "PJ_IS_LITTLE_ENDIAN is not defined!"

/usr/local/pjsip/include/pj/config.h:1165:4: error: #error "PJ_IS_BIG_ENDIAN is not defined!"

解决：在config.h文件中宏定义

#define PJ_IS_BIG_ENDIAN 0

#define PJ_IS_LITTLE_ENDIAN 1

这样就能编译通过了。
