https://log4cpp.sourceforge.net/ 二、下载
1.1.4版本下载地址 https://cytranet.dl.sourceforge.net/project/log4cpp/log4cpp-1.1.x%20%28new%29/log4cpp-1.1/log4cpp-1.1.4.tar.gz?viasf1 三、编译
1.目录结构如下
[jnjn log4cpp]$ tar -xvf log4cpp-1.1.4.tar.gz; cd log4cpp
[jnjn log4cpp]$ ls
aclocal.m4 bcb5 config configure doc jamfile log4cpp.cfg log4cpp.m4 log4cpp.spec Makefile msvc10 NEWS src TODO
AUTHORS ChangeLog config.log configure.in include liblog4cpp log4cpp-config log4cpp.pc log4cpp.spec.in Makefile.am msvc6 openvms tests
autogen.sh CMakeLists.txt config.status COPYING INSTALL libtool log4cpp-config.in log4cpp.pc.in m4 Makefile.in msvc7 README THANKS
[jnjn log4cpp]$
2.configure 编译
configure编译默认 动态库 和 静态库 都会编译
tar -xvf log4cpp-1.1.4.tar.gz; cd log4cpp
./configure --prefix$PWD/liblog4cpp
make install
ls liblog4cpp/3.cmake 编译
cmake 编译需要先运行 ./configure 生成 config.h另外 cmake 编译默认只编译静态库即-DBUILD_SHARED_LIBSOFF动态库需要打开-DBUILD_SHARED_LIBSON选项同时支支持编译一种
./configure
tar -xvf log4cpp-1.1.4.tar.gz; cd log4cpp
mkdir build;cd build
cmake -DCMAKE_INSTALL_PREFIX$PWD/liblog4cpp -DBUILD_SHARED_LIBSON ..
make
make install
ls liblog4cpp四、测试
源码目录下的tests目录有基本上所有示例代码如testRollingFileAppender.cpp回滚写日志文件
编译方式也很简单
testRollingFileAppender.cpp
g testRollingFileAppender.cpp -I../include -L../lib -l:liblog4cpp.atestPattern.cpp
[jnjn tests]$ g testPattern.cpp -I../include -L../lib -l:liblog4cpp.a
[jnjn tests]$ ./a.out
