由于已定义而导致的链接器错误
自从我编写任何使用 LibCurl 的 .dll 插件以来已经大约一年了，但我决定今晚开始编写另一个插件。不幸的是，我已经与相同的链接器错误作斗争近 4 个小时了，我完全迷失了。
我正在静态构建 LibCurl，除了出现以下链接器错误之外，它在大多数情况下似乎都很好。
1>MSVCRT.lib(MSVCR90.dll) : error LNK2005: _calloc already defined in memoverride.obj
1>MSVCRT.lib(MSVCR90.dll) : error LNK2005: _realloc already defined in memoverride.obj
1>MSVCRT.lib(MSVCR90.dll) : error LNK2005: _free already defined in memoverride.obj
1>MSVCRT.lib(MSVCR90.dll) : error LNK2005: _malloc already defined in memoverride.obj
1>MSVCRT.lib(MSVCR90.dll) : error LNK2005: __strdup already defined in memoverride.obj
1>MSVCRT.lib(MSVCR90.dll) : error LNK2005: __malloc_crt already defined in memoverride.obj
我已经尝试过...
1) 重新组织我包含的库，因为 MSDN 说 LNK2005 是由此引起的。
2) 通过 MSVC 应用程序重建 LibCurl 库，然后通过命令行工具。
3) 排除引起问题的库。
还有很多我现在都不记得的事情了。谁能帮我提供一些有关如何解决这些问题的信息？
It has been about a year since I wrote any .dll plugins that use LibCurl, but I decided to start on another one tonight. Unfortunately, I have been combating the same linker errors for almost 4 hours now, and I am completely lost.
I am statically building LibCurl, and it appears to be fine for the most part, except I am getting the following linker errors.
1>MSVCRT.lib(MSVCR90.dll) : error LNK2005: _calloc already defined in memoverride.obj
1>MSVCRT.lib(MSVCR90.dll) : error LNK2005: _realloc already defined in memoverride.obj
1>MSVCRT.lib(MSVCR90.dll) : error LNK2005: _free already defined in memoverride.obj
1>MSVCRT.lib(MSVCR90.dll) : error LNK2005: _malloc already defined in memoverride.obj
1>MSVCRT.lib(MSVCR90.dll) : error LNK2005: __strdup already defined in memoverride.obj
1>MSVCRT.lib(MSVCR90.dll) : error LNK2005: __malloc_crt already defined in memoverride.obj
I have tried...
1) Reorganizing my included libs due to MSDN saying LNK2005 was caused by this.
2) Rebuilding the LibCurl lib through MSVC Application, then through the Command-Line tool.
3) Excluding the libs that are causing issues.
and a bunch of other things that I cannot even remember now. Can anyone help me out with some information as to how I can solve these?

问题是我的 .dll 是 /MT，而 libcurl 是 /MD。另外，我最初阻止了“libcmt”，因此当我将 libcurl 切换到 /MT 时，它会喷出错误。
Problem was my .dll was /MT while the libcurl was /MD. Also, I had initially blocked "libcmt", so when I was switching libcurl to /MT, it was spewing errors.
