您好我正在尝试升级已在Windows 7上以32位到64位构建的项目。我在应用程序中使用了xerces 2_7 dll，因此我下载了xerces2_7_0版本的源代码并在64位中构建库。没问题，直到这里。但是当我尝试通过它将这个库挂钩到我的项目时会抛出链接器错误。以下是错误

所以我怀疑我是否真的在64位中构建了这个xerces 2_7_0并将测试项目编写为64位控制台应用程序并试图挂钩这个xerces库并能够成功构建项目（使用我正在制作的同一组调用我的项目）
我使用依赖walker来检查所有依赖项; 当我在64位xerces dll上尝试依赖walker时，我发现打开文件时出错，下面是错误：
Error: The Side-by-Side configuration information for "c:\users\vivek\desktop\xerces64bit\x64\debug\XERCES64BIT.EXE" contains errors. The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail (14001).
Error: At least one required implicit or forwarded dependency was not found.
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.
任何想法我做错了以及为什么它没有抱怨我的64位测试应用程序。顺便说一下，我使用的是Visual Studio 2008。 感谢
Update 1:
好的，我将依赖性walker错误减少到2
Error: The Side-by-Side configuration information for "c:\users\vivek\desktop\xerces64bit\x64\debug\XERCES64BIT.EXE" contains errors. The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail (14001).
Error: At least one required implicit or forwarded dependency was not found.
其他2个错误是因为我使用的依赖性walker是32位可执行文件。现在我使用64位依赖性walker，但我仍然看到2个错误。
Update 2:
我通过将CRT更改为/ MT来消除2个错误。但我仍然无法将此库与我的项目链接。
答案 0 :(得分：0)
我明白了。这是语言设置的问题。在Configuration Properties - ＆gt; C/C++ - ＆gt; Language下，Treat wchar_t as Built in Type在我的项目中设置为No，我正在使用选项集构建xerces库是的
这产生了不同。
