电子原生插件在Windows上失败 [英] Electron native addon failing on windows
问题描述
我有一个本地插件，该插件在未包装的电子应用程序上使用openSSL库. 在Windows 10上可以使用，在Windows 7上不能使用，我收到此消息:
I have a native addon that uses openSSL library on a unpacked electron app. On a windows 10 it works and on a windows 7 it's not working , I am receiving this:
Error: The specified module could not be found.
\\?\C:\Program Files (x86)\AppX Player\resources\app\src\addon\foo.node

我针对电子的Windows ia32架构，并按如下所示对其进行了重建:
I am targeting a windows ia32 architecture for electron and I rebuild it like the following:
node-gyp rebuild --target=1.3.1 --arch=ia32 --dist-url=https://atom.io/download/atom-shell --verbose
文件的绑定gyp如下所示，并且基于这个.它使用openSSL静态库
The binding-gyp of the file looks like this and is based on this. It uses the openSSL static library

以防万一缺少dll(它不应该像我链接静态库那样)，我在exe的同一级别上添加了openSSL dll.还有什么可能导致这种行为?
Just in case it was a dll missing (it should not be as I was linking the static library) I added the openSSL dll on the same level of the exe. What else may be causing this behaviour?
修改 安装OpenSSL二进制文件可以正常工作，我认为静态链接可以解决这一问题，因此我不会依赖于外部dll的
Edit Installing OpenSSL binaries make it works, i thought the static linking would take care of that so I wouldn't depend on external dll's
编辑2 如果我可以打包静态库并将其捆绑在".node"文件中，那么一切都会解决.在.node文件上使用dependency walker告诉我它需要dll，而我需要的是在上面具有dll代码.
Edit 2 Everything would be solved if I could pack the static library and bundle it on the ".node" file. Using dependency walker on the .node file shows me that it is requiring the dll and what I need is for it to have the dll code on it.
推荐答案
在 http:/上显示lib /slproweb.com/products/Win32OpenSSL.html 似乎只是对仍在使用它的dll的包装. 我误以为node-gyp只是在编译东西而没有依赖关系，这是不正确的. 我在此处找到了另一个预编译的openssl库.
Turns out the lib on http://slproweb.com/products/Win32OpenSSL.html seems to be just a wrapper around the dll that still uses it. I misguided thought that node-gyp was just compiling the thing without the dependency which is not true. I found another precompiled openssl lib here that did the trick.
所以总结一下: 我需要在电子下使用OpenSSL运送某些东西，但电子不会像节点那样暴露OpenSSL并将其切换为borinSSL. 我遵循了tooTallNate的文章，该文章推荐了一个静态库，并假定该静态库是正确的，并且我以某种方式需要DLL，并且我假定node-gyp没有捆绑使用的静态库. 将lib换成另一个(或者最好自己编译)就可以了.
So to wrap up: I needed to ship something with OpenSSL under electron but electron does not expose OpenSSL like node does and switchs it for borinSSL. I followed tooTallNate article that recommended a static library and assumed the static library was right and I was somehow needing the DLL and I assumed node-gyp was not bundling the used static library. Switching the lib for another one (or better yet compiling it myself) did the trick.
