Boost-log链接器错误 [英] Boost-log linker error

问题描述

我已经从源码下载并构建了Boost 1.55。我试图使用Boost-log。在基本情况下（ http： //boost-log.sourceforge.net/libs/log/doc/html)/log/tutorial.html#log.tutorial.trivial 它的工作正常没有任何问题，但是当我尝试使用一些更高级功能（像这样 - http：//boost-log.sourceforge。 net / libs / log / example / doc / tutorial_fmt_stream.cpp ）我收到此错误：

所以基本上不能查找函数convert（...），code_convert（...）和codecvt（...）in .lib文件。

我已经尝试添加所有发布库（.lib文件，同时建立提升）到额外的库，一般我认为visual studio找到所有的库，但不能在库中找到这些功能。任何想法如何可以解决这个问题？

我使用visual studio 2010（msvc10.0），32位，发布和调试从源代码构建Boost 1.55。我在Windows 7 x64上工作。

解决方案

我有同样的问题，我可以通过更改VisualStudio 2010上的一个项目属性来修复它。

转到：

属性页 - > ConfigurationProperties - > C / C ++ - >语言 - >处理WChar_t类型： strong>是（/ Zc：wchar_t）

我希望它也对您有帮助：）

小心，

i've downloaded and builded Boost 1.55 from source. I'm trying to use Boost-log. In basic case (http://boost-log.sourceforge.net/libs/log/doc/html)/log/tutorial.html#log.tutorial.trivial it's working fine without any problems, but when i try to use some more advanced features(like this - http://boost-log.sourceforge.net/libs/log/example/doc/tutorial_fmt_stream.cpp ) i'm getting this error:

main.obj : error LNK2019: unresolved external symbol "void __cdecl boost::filesystem::path_traits::convert(char const *,char const *,class std::basic_string,class std::allocator> &,class std::codecvt const &)" (?convert@path_traits@filesystem@boost@@YAXPBD0AAV?$basic_string@GU?$char_traits@G@std@@V?$allocator@G@2@@std@@ABV?$codecvt@GDH@5@@Z) referenced in function "void __cdecl boost::filesystem::path_traits::dispatch,class std::allocator > >(class std::basic_string,class std::allocator > const &,class std::basic_string,class std::allocator > &,class std::codecvt const &)" (??$dispatch@V?$basic_string@GU?$char_traits@G@std@@V?$allocator@G@2@@std@@@path_traits@filesystem@boost@@YAXABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@AAV?$basic_string@GU?$char_traits@G@std@@V?$allocator@G@2@@4@ABV?$codecvt@GDH@4@@Z)

So basically it can't find functions convert(...), code_convert(...) and codecvt(...) in .lib files.

I've already tried to add all release libraries (.lib files made while building boost) to "additional libraries" and generally i think that visual studio find all libraries, but can't find those functions in libraries. Any ideas how can i fix this?

I've build Boost 1.55 from source using visual studio 2010 (msvc10.0), 32 bit, release and debug. I'm working on windows 7 x64.

解决方案

I had the same problem and I could fix it by changing one of the Project properties on VisualStudio 2010.

Go to:

Property Pages -> ConfigurationProperties -> C/C++ -> Language -> Treat WChar_t As Built in Type:

And set the property to:

Yes (/Zc:wchar_t)

I hope it will be helpful for you too :)
