今天终于完成了对log4cpp在unix下的使用,下面是一些总结

1.将log4cpp-0.3.5rc3拷贝到unix下

2.进入log4cpp-0.3.5rc3目录，运行命令configure

3.使用make命令进行编译，会看到一些错误

首先是出错位置priority.hh

class LOG4CPP_EXPORT Priority {

public:

static const int MESSAGE_SIZE=8;

///// Some other declarations //////

};

解决方法

将代码改成

static const int MESSAGE_SIZE;

在priority.cpp里加一句

#include "PortabilityImpl.hh"

#include <log4cpp/Priority.hh>

#include <cstdlib>

const int log4cpp::Priority::MESSAGE_SIZE=8;

然后是"../include/log4cpp/FixedContextCategory.hh", line 171: Warning: log4cpp::FixedContextCategory::addA

ppender hides the virtual function log4cpp::Category::addAppender(log4cpp::Appender*).

"../include/log4cpp/FixedContextCategory.hh", line 171: Warning: log4cpp::FixedContextCategory::owns

Appender hides the virtual function log4cpp::Category::ownsAppender(log4cpp::Appender*, __rwstd::__r

b_tree<log4cpp::Appender*, std::pair<log4cpp::Appender*const, bool>, __rwstd::__select1st<std::pair<

log4cpp::Appender*const, bool>, log4cpp::Appender*>, std::less<log4cpp::Appender*>, std::allocator<s

td::pair<log4cpp::Appender*const, bool>>>::iterator&).

"FixedContextCategory.cpp", line 47: Error: Could not find a match for log4cpp::FixedContextCategory

::addAppender(log4cpp::Appender*).

需要修改FixedContextCategory.hh：

virtual void addAppender(Appender* appender) throw();

为 virtual void addAppender(Appender* appender) const throw();

FixedContextCategory.cpp：

virtual void addAppender(Appender* appender) throw();

为 virtual void addAppender(Appender* appender) const throw();

再次进行编译，就可以通过了,会在src目录生成liblog4cpp.la文件

4.测试

进入tests目录，使用make进行编译，会报"testbench.cpp", line 66: Error: The operation "log4cpp::CategoryStream << std::basic_string<char, s

td::char_traits<char>, std::allocator<char>>" is illegal.

"testbench.cpp", line 85: Error: The operation "log4cpp::CategoryStream << std::basic_string<char, s

td::char_traits<char>, std::allocator<char>>" is illegal.

将85行修改为： s<< log4cpp::CategoryStream::ENDLINE;

将66行修改为： log << log4cpp::Priority::ERROR;//log << str;

运行testmain cpp.log,在当前目录下会生成cpp.log的日志文件。
