【C++】CentOS环境搭建-安装log4cplus日志组件包及报错解决方案

news2024/10/5 14:20:47

log4cplus简介

log4cplus是C++编写的开源的日志系统，前身是java编写的log4j系统，受Apache Software License保护，作者是Tad E. Smith。

log4cplus具有线程安全、灵活、以及多粒度控制的特点，通过将日志划分优先级使其可以面向程序调试、运行、测试、和维护等全生命周期。你可以选择将日志输出到屏幕、文件、NT event log、甚至是远程服务器；通过指定策略对日志进行定期备份等等。

1.安装必要的依赖项：

sudo yum install -y gcc-c++ make cmake
sudo yum install -y openssl-devel

2.下载log4cplus源代码

官网下载地址：https://sourceforge.net/projects/log4cplus/files/log4cplus-stable/2.0.7/

3.编译和安装log4cplus

./configure
make
make install

效果如下：

bin:/usr/bin:/usr/local/bin:/root/bin:/usr/local/bin:/usr/local/bin:/usr/local/bin:/root/bin:/usr/local/bin:/root/bin:/sbin" ldconfig -n /usr/local/include/log4cplus/lib
----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/include/log4cplus/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
 /usr/bin/mkdir -p '/usr/local/include/log4cplus/lib/pkgconfig'
 /usr/bin/install -c -m 644 log4cplus.pc '/usr/local/include/log4cplus/lib/pkgconfig'
make[3]: Leaving directory `/root/log4cplus-REL_2_0_8'
make[2]: Leaving directory `/root/log4cplus-REL_2_0_8'
make[1]: Leaving directory `/root/log4cplus-REL_2_0_8'
[root@localhost log4cplus-REL_2_0_8]#

OK…成功了

测试：

main.cpp

#include <log4cplus/logger.h>
#include <log4cplus/configurator.h>
#include <log4cplus/loggingmacros.h>

#include <iostream>

using namespace std;
int main(int argc, char **argv)
{
    using namespace log4cplus;
    BasicConfigurator config;
    config.configure();

    Logger logger = Logger::getInstance("main");
    LOG4CPLUS_ERROR(logger, "Hello, error!");
    LOG4CPLUS_WARN(logger, "Hello, warn!");
    LOG4CPLUS_INFO(logger, "Hello, info!");
    LOG4CPLUS_DEBUG(logger, "Hello, debug!");

    return 0;
}

set(CMAKE_CXX_STANDARD 20)

add_executable(log4cpuls_eample main.cpp)
target_link_libraries(${PROJECT_NAME} log4cplus)
