如何解决LNK1104错误与提高文件系统库中MSCV？ [英] How do I resolve LNK1104 error with Boost Filesystem Library in MSCV?

问题描述

我有麻烦我的项目链接到升压（1.37.0版本）在Microsoft Visual C ++ 2008例preSS版文件系统库文件。 Filesystem库为不是仅头库。我一直在关注的 入门在Windows 引导张贴的官方提振网页上。下面是我所采取的步骤：

1. 我用的bjam构建使用LIB文件的完整集合：

    的bjam --build-DIR =C：\\ Program Files文件\\提升\\集结助推--toolset = MSVC --build型=完整
    




2. 我复制的 /库的目录（位于 C：\\ Program Files文件\\提升\\ build中 - 升压\\提升\\ bin.v2 ），以<我> C：\\ Program Files文件\\提升\\ boost_1_37_0 \\库

。


3. 在Visual C ++，在项目>属性>附加库目录我添加这些路径：

   
   
   • C：\\ Program Files文件\\提升\\ boost_1_37_0 \\库
   
   
   • C：\\ PROGRAM Files\\boost\\boost_1_37_0\\libs\\filesystem\\build\\msvc-9.0ex$p$pss\\debug\\link-static\\threading-multi
   
   

   我添加了第二个绝望的。这是确切的目录，其中 libboost_system-vc90-MT-GD-1_37.lib 所在。




4. 在配置属性> C / C ++>常规>附加包含目录添加以下路径：

   
   
   • C：\\ Program Files文件\\提升\\ boost_1_37_0
   
   



5. 然后，把锦上添花，在工具>选项VC ++目录>库文件的，我加在第3步中提到的相同的目录。

尽管如此，当我建立我的项目，我收到以下错误：

 致命错误LNK1104：无法打开文件'libboost_system-vc90-MT-GD-1_37.lib
 

此外，这里是code，我试图编译以及前述方式目录的屏幕截图，其中（assumedly正确）的lib文件所在：

 的#include助推/ filesystem.hpp//包括所有需要的Boost.Filesystem的声明
＃包括LT＆;＆iostream的GT; //性病::法院
使用boost ::文件系统; //为便于教程presentation的;
                                  //命名空间别名是在现实code preferred实践使用命名空间std;诠释的main（）
{
    COUT＆LT;＆LT; 你好，世界！ ＆LT;＆LT; ENDL;    返回0;
}
 

解决方案

费鲁乔的回答包含了大部分的洞察力。然而，Pukku使我认识到我的错误。我张贴我自己的答案给出全面的解释。由于费鲁乔解释说，文件系统依赖于两个库。对我来说，它们是：

• libboost_system-vc90-MT-GD-1_37.lib


• libboost_filesystem-vc90-MT-GD-1_37.lib

我一定没有注意到，当我为提供目录 libboost_filesystem-vc90-MT-GD-1_37.lib ，错误输出

改变

 致命错误LNK1104：无法打开文件'libboost_filesystem-vc90-MT-GD-1_37.lib
 

到

 致命错误LNK1104：无法打开文件'libboost_system-vc90-MT-GD-1_37.lib
 

害我认为错误是坚持。这导致我张贴一些相当不准确的信息。此外，读取文件系统需要两个库后，我现在看到的关键字舞台的bjam的命令的意义。直供

 的bjam --build-DIR =C：\\ Program Files文件\\提升\\集结助推--toolset = MSVC --build型=完整的舞台
 

原因的bjam放置一个额外的目录，取名为段在 boost_1_37_0 目录。此文件夹包含一个名为 / lib目录的文件夹，里面有所有的lib文件的副本在一个地方。这是方便的Visual C ++，因为你可以用这个单一的目录提供它，它会采取所有的依赖护理。

I am having trouble getting my project to link to the Boost (version 1.37.0) Filesystem lib file in Microsoft Visual C++ 2008 Express Edition. The Filesystem library is not a header-only library. I have been following the Getting Started on Windows guide posted on the official boost web page. Here are the steps I have taken:

1. I used bjam to build the complete set of lib files using:

   bjam --build-dir="C:\Program Files\boost\build-boost" --toolset=msvc --build-type=complete
   

2. I copied the /libs directory (located in C:\Program Files\boost\build-boost\boost\bin.v2) to C:\Program Files\boost\boost_1_37_0\libs.

3. In Visual C++, under Project > Properties > Additional Library Directories I added these paths:

   • C:\Program Files\boost\boost_1_37_0\libs
   • C:\Program Files\boost\boost_1_37_0\libs\filesystem\build\msvc-9.0express\debug\link-static\threading-multi

   I added the second one out of desperation. It is the exact directory where libboost_system-vc90-mt-gd-1_37.lib resides.

4. In Configuration Properties > C/C++ > General > Additional Include Directories I added the following path:

   • C:\Program Files\boost\boost_1_37_0

5. Then, to put the icing on the cake, under Tools > Options VC++ Directories > Library files, I added the same directories mentioned in step 3.

Despite all this, when I build my project I get the following error:

fatal error LNK1104: cannot open file 'libboost_system-vc90-mt-gd-1_37.lib'

Additionally, here is the code that I am attempting to compile as well as a screen shot of the aformentioned directory where the (assumedly correct) lib file resides:

#include "boost/filesystem.hpp"   // includes all needed Boost.Filesystem declarations
#include <iostream>               // for std::cout
using boost::filesystem;          // for ease of tutorial presentation;
                                  //  a namespace alias is preferred practice in real code

using namespace std;

int main()
{
    cout << "Hello, world!" << endl;

    return 0;
}

解决方案

Ferruccio's answer contains most of the insight. However, Pukku made me realize my mistake. I am posting my own answer to give a full explanation. As Ferruccio explained, Filesystem relies on two libraries. For me, these are:

• libboost_system-vc90-mt-gd-1_37.lib
• libboost_filesystem-vc90-mt-gd-1_37.lib

I must not have noticed that when I supplied the directory for libboost_filesystem-vc90-mt-gd-1_37.lib, the error output changed from

fatal error LNK1104: cannot open file 'libboost_filesystem-vc90-mt-gd-1_37.lib'

to

fatal error LNK1104: cannot open file 'libboost_system-vc90-mt-gd-1_37.lib'

Causing me to think that the error was persisting. This lead me to post some rather inaccurate information. Also, after reading that Filesystem requires two libraries, I now see the significance of the keyword stage for the bjam command. Supplying

bjam --build-dir="C:\Program Files\boost\build-boost" --toolset=msvc --build-type=complete stage

Causes bjam to place an additional directory, aptly named stage, in the boost_1_37_0 directory. This folder contains a folder named /lib, which has copies of all of the lib files in one place. This is convenient for Visual C++ because you can supply it with this single directory and it will take care of all of the dependencies.
