在vs 2010 C ++中构建log4cxx [英] building log4cxx in vs 2010 c++

问题描述

这让我发疯，我试图构建log4cxx库以便在我一直在使用的c ++项目中使用.我在运行VS2010 Express C ++版本的Win7主机上.我已按照每个log4cxx指示()的指示进行操作，包括下载apr 和apr-util并修饰.hw文件，但不幸的是，当我尝试加载log4cxx.dsw解决方案并将其转换为当前VS时，尝试构建apr.apr/dsw和一堆错误时会收到错误消息其他相关的.dsw文件.有什么建议吗?

This is driving me crazy, I'm trying to building the log4cxx library in order to use in a c++ project I've been using. I'm on a win7 host running VS2010 express c++ edition. I've followed the directions per the log4cxx directions ( ) including downloading apr and apr-util and motifying the .hw files, but I unfortunately, when ever I try to load the log4cxx.dsw solution and convert it to the current VS, I receive an error trying to build apr.apr/dsw and a bunch of other dependent .dsw files. Any suggestions?

具体地说，我看到的是:

Specifically, what I am seeing is:

The Project file 'C:\...projects\apr-util\xml\expat\lib\xml.dsp' cannot be loaded. Do you want to remove the unloadable project from the solution?

我看到了一堆其他的.dsp文件.

I see this for a bunch of other .dsp files.

然后在VC的输出框中:

then in the output box in VC:

C:\Users\x\Documents\Visual Studio 2010\Projects\apr\apr.dsp : error  : Project upgrade failed.

C:\Users\x\Documents\Visual Studio 2010\Projects\apr-util\xml\expat\lib\xml.dsp : error  : Project upgrade failed.

C:\Users\x\Documents\Visual Studio 2010\Projects\apr-util\aprutil.dsp : error  : Project upgrade failed.

C:\Users\x\Documents\Visual Studio 2010\Projects\apache-log4cxx-0.10.0\projects\log4cxx.dsp : error  : Project upgrade failed.

谢谢

推荐答案

您必须按照以下步骤操作，以使log4cxx(版本0.10.0)与VS2010一起使用:

You have to follow these steps to get log4cxx (Version 0.10.0) working with VS2010:

1. 从此处
下载最新的log4cxx软件包.
2. 从此处
下载apr和apr-util ZIP软件包
3. 将log4cxx，apr和apr-util提取到同一目录
4. 将apr_VERSION和apr-util_VERSION文件夹重命名为apr和apr-util，从而得到一个包含三个文件夹的目录:apache-log4cxx-0.10.0，apr和apr-util
5. 切换到log4cxx目录并执行configure.bat
6. 更改为apr-util/include目录，并在您选择的文本编辑器中打开apu.hw
7. 找到条目#define APU_HAVE_APR_ICONV，将其设置为0并保存文件
8. 从同一目录中打开apr_ldap.hw并找到条目#define APR_HAS_LDAP，将其设置为0并保存文件.
9. 切换到log4cxx/projects目录，并使用VS2010打开log4cxx.dsw.为每个项目(apr，apr-util，log4cxx，xml)回答是/确定来回答VS2010的转换提示

1. Download the latest log4cxx package from here
2. Download apr and apr-util ZIP packages from here
3. Extract log4cxx, apr und apr-util to the same directory
4. Rename the apr_VERSION and apr-util_VERSION folder to apr and apr-util resulting in a directory with three folder: apache-log4cxx-0.10.0, apr and apr-util
5. Change into the log4cxx directory and execute configure.bat
6. Change to apr-util/include direcotry and open apu.hw in a texteditor of your choice
7. Find the entry #define APU_HAVE_APR_ICONV, set it to 0 and save the file
8. Open apr_ldap.hw from the same directory and find the entry #define APR_HAS_LDAP, set it to 0 and save the file, too.
9. Change to log4cxx/projects directory and open log4cxx.dsw with VS2010. Answer the converting prompts of VS2010 with yes/ok for each project (apr, apr-util, log4cxx, xml)

好吧，如果您现在点击构建，那么您将看到大约2000个错误，而有趣的硬"部分正是从这里开始的:

Ok if you hit build now then you will see around 2000 errors and that is where the interesting and "hard" part starts:

• Ctrl + F并找到"LOG4CXX_LIST_DEF"宏的每个条目.您必须将这些条目移出其相关类，并移到同一类之前.有时您也需要移动typedef或在宏之前添加类.

一些示例:

    // telnetadapter.h
    ...
    typedef log4cxx::helpers::SocketPtr Connection;
    LOG4CXX_LIST_DEF(ConnectionList, Connection);
    class LOG4CXX_EXPORT TelnetAppender : public AppenderSkeleton
    ...

    // appender.h
    ...
    class Appender;
    LOG4CXX_PTR_DEF(Appender);
    LOG4CXX_LIST_DEF(AppenderList, AppenderPtr);

    class Layout;
    typedef log4cxx::helpers::ObjectPtrT<Layout> LayoutPtr;

    ...

    class LOG4CXX_EXPORT Appender :
                public virtual spi::OptionHandler
    {
    ...

• 如果编译器抱怨KeySet不是LoggingEvent的成员，则只需删除作用域(由于我们在上一步中将类型移到类外部，因此这些类型不再在类内部)

示例:

   // old
   LoggingEvent::KeySet set;
   // new
   KeySet set;

• 如果编译器抱怨insert_iterator不在名称空间std中，请在源文件的include部分中添加#include <iterator>.

  最后但并非最不重要的一点是，右键单击log4cxx项目并选择Add References，然后选择其他3个项目作为参考

  Last but not least, right-click on log4cxx project and select Add References and select the other 3 projects as reference
