将VS2003迁移到VS2005时Comdef.h链接问题（comsuppwd和comsuppd之间） [英] Comdef.h linking problem (between comsuppwd & comsuppd) when migrating VS2003 to VS2005

问题描述

我有一个链接错误：
"comsuppwd.lib（comutil.obj）：错误LNK2005：" class _variant_t vtMissing" （？vtMissing @@ 3V_variant_t @@ A）已经在comsuppd.lib（comutil.obj）中定义了
1>创建库D：\ BackTestTesting V2 \BackTestingAppli Portefolio \ BackTestingAppli Portefolio\bin\Debug / BackTesting.lib和对象D：\ BackTestTesting V2 \ BackTestingAppli Portefolio \ BackTestingAppli Portefolio \bin \Debug / BackTesting .exp
1> D：\ BackTestTesting V2 \ BackTestingAppli Portefolio \ BackTestingAppli Portefolio \bin\Debug \BackTesting.dll：致命错误LNK1169：找到一个或多个多重定义的符号"

我更改了comdef.h文件：

Hi,

I've got a linking error :
"comsuppwd.lib(comutil.obj) : error LNK2005: "class _variant_t vtMissing" (?vtMissing@@3V_variant_t@@A) already defined in comsuppd.lib(comutil.obj)
1>   Creating library D:\BackTesting V2\BackTestingAppli Portefolio\BackTestingAppli Portefolio\bin\Debug/BackTesting.lib and object D:\BackTesting V2\BackTestingAppli Portefolio\BackTestingAppli Portefolio\bin\Debug/BackTesting.exp
1>D:\BackTesting V2\BackTestingAppli Portefolio\BackTestingAppli Portefolio\bin\Debug\BackTesting.dll : fatal error LNK1169: one or more multiply defined symbols found"

I changed the comdef.h file from :

#pragma comment （ lib ，" comsupp.lib" ）

推荐答案

我在VS 2008中看到这种情况发生时有"和"的图书馆;将wchar_t视为内置类型"  设置为NO，导入库的项目设置为"YES"

I've seen this happen in VS 2008 when linking with a library that has "Treat wchar_t as Built-in Type"  set to NO and the project importing the library is set to "YES"
