log4cxx vs2019编译

使用VS2019编译“apache-log4cxx-0.10.0"的详细教程附带测试代码和编译好的库。

一：下载需要的压缩文件

在log4cxx官方主页：https://logging.apache.org/log4cxx/latest_stable/

下载https://archive.apache.org/dist/logging/log4cxx/0.10.0/apache-log4cxx-0.10.0.zip

在github地址：http://archive.apache.org/dist/apr/

下载：apr-1.6.5-win32-src.zip，apr-iconv-1.2.2-win32-src.zip,apr-util-1.2.10-win32-src.zip

将三个压缩包解压到同一个目录，apr-1.6.5改名为apr，apr-util-1.2.10改名为apr-util,apr-iconv-1.2.2改名为apr-iconv

二：修改宏定义及文件内容

1：进入apr-util\include修改apr_ldap.hw的APR_HAS_LDAP宏定义为0，apu.hw的APU_HAVE_APR_ICONV宏定义为0

2：进入apache-log4cxx-0.10.0执行configure.bat，进入projects，打开log4cxx.dsw，升级工程

修改log4cxx.vcxproj文件：AdditionalDependencies最后添加uuid.lib;rpcrt4.lib;

log4cxx\apr\include中添加一个文件：
apr_escape_test_char.h

内容：

/* this file is automatically generated by gen_test_char, do not edit. "make include/private/apr_escape_test_char.h" to regenerate. */
//编译 apr 1.6.5 需要的头文件 apr_escape_test_char.h
#define T_ESCAPE_SHELL_CMD     (1)
#define T_ESCAPE_PATH_SEGMENT  (2)
#define T_OS_ESCAPE_PATH       (4)
#define T_ESCAPE_ECHO          (8)
#define T_ESCAPE_URLENCODED    (16)
#define T_ESCAPE_XML           (32)
#define T_ESCAPE_LDAP_DN       (64)
#define T_ESCAPE_LDAP_FILTER   (128)

static const unsigned char test_char_table[256] = {
    224,222,222,222,222,222,222,222,222,222,223,222,222,223,222,222,222,222,222,222,
    222,222,222,222,222,222,222,222,222,222,222,222,6,16,127,22,17,23,49,17,
    145,145,129,80,80,0,0,18,0,0,0,0,0,0,0,0,0,0,16,87,
    119,16,119,23,16,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
    0,0,0,0,0,0,0,0,0,0,0,23,223,23,23,0,23,0,0,0,
    0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
    0,0,0,23,23,23,17,222,222,222,222,222,222,222,222,222,222,222,222,222,
    222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,
    222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,
    222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,
    222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,
    222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,
    222,222,222,222,222,222,222,222,222,222,222,222,222,222,222,222 
};

 打开 apr/apr.vcxproj：
删除以下内容：

<Command Condition="'$(Configuration)|$(Platform)'=='Release|x64'">type .\include\apr.hw &gt; .\include\apr.h</Command>
<Message Condition="'$(Configuration)|$(Platform)'=='Release|x64'">Creating apr.h from apr.hw</Message>
<Outputs Condition="'$(Configuration)|$(Platform)'=='Release|x64'">.\include\apr.h;%(Outputs)</Outputs

<Command Condition="'$(Configuration)|$(Platform)'=='Debug|x64'">type .\include\apr.hw &gt; .\include\apr.h</Command>
<Message Condition="'$(Configuration)|$(Platform)'=='Debug|x64'">Creating apr.h from apr.hw</Message>
<Outputs Condition="'$(Configuration)|$(Platform)'=='Debug|x64'">.\include\apr.h;%(Outputs)</Outputs>

修改src\main\cpp\stringhelper.cpp文件：
添加:#include <iterator>
修改src\main\include\log4cxx\log4cxx.h文件

//原来
#if defined(LOG4CXX_STATIC)
#define LOG4CXX_EXPORT
//改为
#if defined(LOG4CXX_STATIC) || (defined(_MSC_VER) && _MSC_VER >= 1916)
#define LOG4CXX_EXPORT
 
//原来
#if defined(_MSC_VER) && !defined(LOG4CXX_STATIC) && defined(LOG4CXX)
//改为
#if defined(_MSC_VER) && _MSC_VER < 1916 && !defined(LOG4CXX_STATIC) && defined(LOG4CXX)
 
//原来
#elif defined(_MSC_VER) && !defined(LOG4CXX_STATIC)
//改为
#elif defined(_MSC_VER) && _MSC_VER < 1916 && !defined(LOG4CXX_STATIC)

 这时编译程序就能编译过啦

三：如何生成.lib文件

修改”log4cxx.h“

由于在代码编辑器中LOG4CXX_EXPORT无法指定是导出还是导入，所以我重新后面加了一下：
在预处理宏中添加LOG4CXX，此时就为导出了！

#if defined(LOG4CXX)
#define LOG4CXX_EXPORT __declspec(dllexport)
#else
#define LOG4CXX_EXPORT __declspec(dllimport)
#endif

四：测试生成的库

#include<log4cxx/logger.h>

#include<log4cxx/propertyconfigurator.h>
using namespace log4cxx;

int main()
{
    //获得一个Logger，这里使用了RootLogger
	//加载log4cxx的配置文件，这里使用了属性文件

	PropertyConfigurator::configure("../config/log4cxx.properties");
	LOG4CXX_INFO(rootLogger, "判断各题错误正确");
    return 0;
}
