如何在我的项目中使用FFTW DLL导入库.lib作为静态.lib? [英] How to use FFTW DLL import library .lib as a static .lib in my project?
问题描述
我了解C ++和编译小型插件(始终基于相似且布局合理的工作流程).尽管目前我需要将FFTW的最新版本编译到一个静态库中(或从编译的版本中获取它，这应该会容易得多)，但这给了我极大的困难.可能是因为我不知道编译的来龙去脉.请注意，我正在使用Visual Studio在Windows上工作.
I've knowledge of C++ and compiling small plug-ins (always based on a similar and laid out workflow). Though currently I need to compile the latest version of FFTW into a static library (or get it from the compiled version which should supposedly be a lot easier) and it's giving me an insanely hard time. Probably because I don't know the ins and outs of compiling. As a note I'm working on Windows with Visual Studio.
因为我真的很想知道这应该如何工作，所以我在这里问这个问题.
Since I really want to know how this should work I'm asking the question here.
基本上，我需要Windows上可以包含在另一个Visual Studio项目中的fftw3f库的静态.lib.
Basically I need a static .lib of fftw3f library on Windows that I can include in another Visual Studio project.
我做的第一件事是从网站上下载FFTW的64位dll(希望我可以使用它). http://www.fftw.org/install/windows.html
The first I did was download the 64 bit dll's of FFTW from the website (hoping I could use this). http://www.fftw.org/install/windows.html
然后，我完成了他们所说的相应步骤，即:在lib.exe中运行以下命令.
Then I've done the accompanying step they stated, that is: Run the following in lib.exe.
lib /def:libfftw3-3.def
lib /def:libfftw3f-3.def
lib /def:libfftw3l-3.def
我也已经完成了此操作，并获得了一个.lib文件，可以在我的项目中正确使用它.我已经能够编译我的项目，但是输出构建显然是动态链接到该库的，而不是将其包含为静态库.
I've done this as well and got a .lib file that I could use in my project correctly. I've been able to compile my project, yet the output build apparently dynamically linked to the library instead of including it as a static library.
我正在将项目编译为.dll，但要求fftw3f库静态包含在我的输出中.
I'm compiling my project to .dll but require the fftw3f library to be statically included in my output.
使用 lib.exe/list libfftw3f-3.lib ，我能够发现lib文件引用了libfftw3f-3.dll.
Using lib.exe /list libfftw3f-3.lib I was able to find out that the lib file was referencing the libfftw3f-3.dll.
根据我的Google搜索结果，这意味着我创建的.lib文件是 DLL导入库，而不是静态库.
According to my google results this would mean the .lib file that I created is a DLL import library instead of static library.
很难弄清楚该如何表达我的问题，因为我不确定该术语是什么以及幕后发生了什么.我猜:
It's hard to figure out how to phrase my question because I'm not sure what the terminology is and what's going on behind the scenes. I guess:
- 如何在我自己的项目中将从lib.exe创建的libfftw3f-3.lib文件用作静态库.这样它就包含在我的输出.dll中，而不是动态链接了?
根据我从评论/答案中学到的知识，我很乐意更新/编辑/重新表达我的问题，以使其他大多数用户更理解，因为我可能会使用术语
推荐答案
您不能期望将DLL转换为静态库.
You cannot expect to convert a DLL into a static library.
为了创建静态库，您需要从其源代码重新编译该库，并使用静态库的输出目标.如果您无法获得源代码，那么您的目标就无法实现.
In order to create a static library you need to re-compile the library from its source code, with an output target that is a static library. If you cannot obtain the source code, then your goal cannot be achieved.
