有没有简单的方法来构建 64 位 JD2XX DLL？
为了从 Java 应用程序访问 FTDI USB 板，我使用 JD2XX 驱动程序包装 (JD2XX.dll)。它在32位系统上工作得很好，但是当它从64位JVM加载时，它说64位JVM不可能加载32位DLL。非常好理解。为了解决这个小问题，我在 64 位系统上安装了 32 位 JVM，它运行良好。非常简单的解决方案，但向客户解释可能会变得非常复杂！
因此，我想创建或以其他方式获取此 JD2XX.dll 文件的 64 位版本。我想知道是否有人成功地做到了这一点，或者我该如何继续。我认为 ftdi-win32 项目中应该有对 32 位 dll 的引用，我可以在 64 位系统上重新编译所有内容之前将其更改为 64 位 dll 引用，但我没有找到。
我将非常感谢任何有关此事的帮助。我觉得我不会很快找到解决这个问题的方法。我描述的文件可以在最新的这些包中找到。
非常感谢你，
MJ
For accessing FTDI USB boards from Java applications, I'm using the JD2XX driver wrapper (JD2XX.dll). It works very fine on 32-bit systems, but when it is loaded from a 64-bit JVM, it says it is impossible for a 64-bit JVM to load a 32-bit DLL. Very understandable. To get past this little problem, I install a 32-bit JVM on the 64-bit systems and it runs fine. Very simple solution, which can become very complicated to explain to a customer, though!
For this reason, I would like to create or otherwise obtain a 64-bit version of this JD2XX.dll file. I would like to know if someone ever did this successfully, or how I could proceed. I thought there should be a reference to the 32-bit dll in the ftdi-win32 project I could change for a 64-bit dll reference before recompiling everything on a 64-bit system, but I didn't find.
I would greatly appreciate any help about this. I don't feel like I'd find a way around this problem on my own anytime soon. The files I describe can be found in the most recent of these packages.
Thank you very much,
MJ

我终于成功生成了 64 位 DLL 文件。 ... :)
以下是我获取它的方法：
如果有人需要的话，生成的文件可供下载。
I finally managed to generate that 64-bit DLL file. ... :)
Here is how I obtained it:
The generated file for download if anyone needs it.
“生成的下载文件”对我不起作用，所以我按照说明自己制作了它，它有效：
http://dev.geogebra.org/download/lib/ftdi/JD2XX_64_2 .08.17.dll
看起来你应该能够通过下载正确版本的 mingw-w64 在 32 位系统（甚至 Linux）上构建 64 位 dll：
https://sourceforge.net/ items/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/sezero_4.5_20111101/
此外，某些链接已过期。这些是当前的：
d2xx.svn.sourceforge.net/viewvc/d2xx/trunk/
www.ftdichip.com/Drivers/D2XX.htm
The "generated file for download" didn't work for me, so I followed the instructions and made it myself, which works:
http://dev.geogebra.org/download/lib/ftdi/JD2XX_64_2.08.17.dll
It also looks like you should be able to build a 64-bit dll on a 32-bit system (or even on linux) by downloading the correct version of mingw-w64:
https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/sezero_4.5_20111101/
Also, some of the links are out of date. These are current:
d2xx.svn.sourceforge.net/viewvc/d2xx/trunk/
