linux 编译安装log4cxx

Apache log4cxx是一个继Apache log4j之后用于C++的日志框架。Apache log4cxx使用Apache Portable Runtime作为大部分的平台相关代码，可以用于任何支持APR的平台。

官网: http://logging.apache.org/log4cxx/

首先从 https://github.com/apache/log4cxx/tree/mcatan 下载源代码，目前最新的版本是0.10.0

git clone https://github.com/apache/log4cxx.git

这时直接./configure 会报错，找不到apr和apr-uitl, 所以还需要先安装这2个包

wget http://mirrors.hust.edu.cn/apache//apr/apr-1.5.2.tar.gz

wget http://mirrors.hust.edu.cn/apache//apr/apr-util-1.5.4.tar.gz

先编译安装apr

tar xzvf apr-1.5.2.tar.gz
cd apr-1.5.2
./configure
make
make install

然后编译安装apr-util

tar xzvf apr-util-1.5.4.tar.gz
cd apr-util-1.5.4
./configure
make
make install

最后编译安装log4cxx

cd log4cxx
./configure
make
make instal

如果不能打印中文日志可以重新 configure编译，如下

./configure --with-charset=utf-8 --with-logchar=utf-8
make
make install

在编译的时候我报了一个错,如下

In file included from ../../../src/main/include/log4cxx/spi/filter.h:24:0,
                 from ../../../src/main/include/log4cxx/filter/andfilter.h:27,
                 from andfilter.cpp:18:

                         typedef spi::KeySet KeySet;
                                             ^

                 from ../../../src/main/include/log4cxx/filter/andfilter.h:27,

                 LOG4CXX_LIST_DEF(KeySet, LogString);

打开报错的文件 loggingevent.h ，将 typedef spi::KeySet KeySet 移动到 KeySet getMDCKeySet() const; 这个函数声明之前

typedef spi::KeySet KeySet;
KeySet getMDCKeySet() const;
