如何解决“错误 LNK2001:无法解析的外部符号”用于在 Visual Studio 2010 C++ 中编写用户定义模型 (FLAC)?
我正在尝试在 Visual Studio Express 2010 C++ 中为 FLAC 用 C++ 编写用户定义模型。最初,我尝试仅通过更改名称来运行(调试和构建)基于 Mohr-Coulomb 准则(在 FLAC 8.0 中提供)的内置应变软化模型。一旦成功,我会尝试按照我的要求修改它。我在VS2010中运行代码。我已经安装了 SDK7.1、VS2010 SP1 等。但是,我收到以下错误消息:
1>------ Build started: Project: i_ssoft, Configuration: Debug x64 ------

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
从错误代码来看,很明显我需要添加一些库,或者我需要将支持库放在同一个项目中目录...我已经尝试过,但仍然收到错误。
I am trying to write a User-defined Model in C++ for FLAC in Visual Studio Express 2010 C++. Initially, I am trying to run (debug and build) the built-in Strain-softening Model based on the Mohr-Coulomb criterion (Available in FLAC 8.0) by changing its name only. Once I succeed to do it, I will try to modify it as per my requirement. I am running the code in VS2010. I have already installed SDK7.1, VS2010 SP1, etc. However, I am getting the following error msg:
1>------ Build started: Project: i_ssoft, Configuration: Debug x64 ------

From the error code, it is clear that I need to add some libraries or I need to place the supporting libraries in the same project directory... which I have tried but still, I am getting the error.
