Question

我正在尝试在Visual Studio 2013下构建log4cxx版本0.10.0。我已经完成了building log4cxx in vs 2010 c++中指定的所有修复。

但是，在尝试创建log4cxx.lib时，它现在在链接阶段失败，并出现以下错误：

unresolved external symbol __InterlockedIncrement referenced in function _apr_atomic_inc32@4
unresolved external symbol __InterlockedExchangeAdd referenced in function _apr_atomic_add32@8
unresolved external symbol __InterlockedExchange referenced in function _apr_atomic_set32@8
unresolved external symbol __InterlockedDecrement referenced in function _apr_atomic_dec32@4
unresolved external symbol __InterlockedCompareExchange referenced in function _apr_atomic_cas32@12

根据MSDN，这些函数应该在kernel32.lib中，我已经将它添加到链接器中，没有任何效果。查看ht elib，这似乎包含_InterlockedIncrement（单个下划线）和_imp_InterlockedIncrement

有谁知道我能做些什么才能让它发挥作用？

此外，Building log4cxx with VS 2012 on Windows 7中建议的修复不会产生任何不同的

Answer 1

以下过程是在VS2013下为32位和64位构建构建Log4CXX的完整过程。请注意，32位版本经过了非常轻微的测试，64位版本的测试稍稍进行了广泛测试（I.E，它是我们正在使用的版本）。

下载apache-log4cxx-0.10.0.zip，apr-x.y.z-win32.src.zip和apr-util-1.5.4-win32.src.zip，其中x，y和z是最新版本。
将内容解压缩到共享目录。
重命名apr-x.y.z和apr-utls-x.y.z以删除版本号。
将修补程序应用于log4cxx中的文件。见下文。
对于32位版本，修补程序apr\atomic\win32\apr_atomic.c。
1. 将defined(_M_IA64) || defined(_M_AMD64))的所有次出现替换为defined(_M_IA64) || defined(_M_AMD64) || (_MSC_VER == 1800))
  
  这只是一个临时修复，但它确实有效。
运行apache-log4cxx-0.10.0\configure.bat。
补丁apr-util。
1. 在include\apu.hw中，将APU_HAVE_APR_ICONV更改为0。
2. 在include\apr_ldap.hw中，将APR_HAS_LDAP更改为0。
将apache-log4cxx-0.10.0\projects\log4cxx.dsw加载到Visual Studio 2013中。系统将提示您升级项目。接受，等待转换完成。这将创建您在下次打开项目时应使用的log4cxx.sln
选择菜单选项Build->Configuration Manager。为log4cxx创建x64项目上下文，包括发布和调试。检查这些项目的构建框。
根据需要升级项目。上一步将导致所有其他项目都需要这个。在解决方案资源管理器中右键单击项目并选择Upgrade VC++ compiler ...。
如果您希望调试库与发行版具有不同的文件名，请右键单击log4cxx项目，然后选择properties。
1. 选择Debug / All platforms配置设置。
2. 将Configuration Properties / General / Target name设置为＆＃34; _d＆＃34;作为文件名的末尾。
3. 将Linker / All Options / Output File设置为＆＃34; _d＆＃34;作为文件名的末尾。
4. 将Linker / All Options / Import Library设置为＆＃34; _d＆＃34;作为文件名的末尾。
在菜单Build -> Configuration manager中选择适当的有效解决方案配置和平台。
构建项目。

以下是log4cxx所需的补丁。

Answer 2

链接错误的原因是APR（Apache Portable Runtime）库。

在文件atomic\win32\apr_atomic.c中，调用各种互锁函数，格式如下：

#if (defined(_M_IA64) || defined(_M_AMD64)) && !defined(RC_INVOKED)
    return InterlockedIncrement(mem) - 1;
#else
    return ((apr_atomic_win32_ptr_fn)InterlockedIncrement)(mem) - 1;
#endif

其中apr_atomic_win32_ptr_fn定义为

typedef WINBASEAPI apr_uint32_t (WINAPI * apr_atomic_win32_ptr_fn)
(apr_uint32_t volatile *);

由于编译器正在构建32位可执行文件，因此使用第二个调用。此转换使编译器不会将InterlockedIncrement识别为内置，并生成对__InterlockedIncrement()的调用，而不是预期的内在调用。

作为临时修复，我编辑了使用与64位版本相同的调用的调用。
