linux 与arm下 log4cplus 安装配置，qtcreator 开发环境

1.log4cplus 下载地址：http://sourceforge.net/projects/log4cplus/files/log4cplus-stable/

2.

使用  log4cplus-1.0.4.2.zip，解压缩

#cd log4cplus-1.0.4.2

#configure --prefix=/home/myplace

#make

#make install
3.
配置库文件与头文件路径
#gedit  /etc/profile   添加
export CPLUS_INCLUDE_PATH=/home/myplace/include:$CPLUS_INCLUDE_PATH
#gedit ~/.bashrc  添加
export LD_LIBRARY_PATH=/home/myplace/lib:$LD_LIBRARY_PATH

注销后，
编写测试程序

#g++ filetime.cpp -I /home/myplace/include/ -L /home/myplace/lib -llog4cplus -o filetime
4.
使用qtcreator 开发环境下,工程文件下  XXX.pro需要添加
LIBS += -L /home/myplace/lib \
    -llog4cplus
如果出现 找不到liblog4cplus-1.0.so.4
则需要多创建一个链接
ln -s /home/myplace/lib/liblog4cplus-1.0.so.4.0.0  /usr/lib/liblog4cplus-1.0.so.4
5.
编译在arm机上运行的程序所使用的库
#cd log4cplus-1.0.4.2
#CC=/opt/arm-2007q1/bin/arm-none-linux-gnueabi-gcc ./configure --prefix=/home/myplace --host=arm-none-linux-gnueabi
其中：CC指定编译器，交叉编译环境的gcc。
--host指定编译平台。
