Error using 'fastcall' module.

[T-Hacker]

Hi, I'm a C++ and Rust developer and I'm not accustomed to using so many tools and modules. You can say I'm a bit lost...

What I want to do is simple. I want to use fastcall module to invoke some native code. Here's what I've tried so far:

1- Added fastcall dependency to the root package.json file.
When I build the project, theses errors appear:

ERROR in ./~/fastcall/es5/benchmarks/importBenchlib.js
Module not found: Error: Cannot resolve module 'ffi' in /home/pedro/electron/test2/node_modules/fastcall/es5/benchmarks
 @ ./~/fastcall/es5/benchmarks/importBenchlib.js 24:10-24

ERROR in ./~/fastcall/es5/lib/es5Support.js
Module not found: Error: Cannot resolve 'file' or 'directory' ../es5 in /home/pedro/electron/test2/node_modules/fastcall/es5/lib
 @ ./~/fastcall/es5/lib/es5Support.js 49:28-54

2- Added 'ffi' module to root package.json dependencies. Build project, the first error is solved, but the second still stands:

ERROR in ./~/fastcall/es5/lib/es5Support.js
Module not found: Error: Cannot resolve 'file' or 'directory' ../es5 in /home/pedro/electron/test2/node_modules/fastcall/es5/lib
 @ ./~/fastcall/es5/lib/es5Support.js 49:28-54

3- At this point, I've reset the project and added the 'fastcall' dependency in the app/package.json. It builds fine, but when I run the application I get this error on console:

Uncaught Error: Module version mismatch. Expected 50, got 51.

I'm aware that the ABIs from electron and my 'node_modules' don't match, so I tried to recompile them with 'electron-rebuild', but still got the same error.

Is it possible to use 'fastcall' with electron-react-boilerplate? Thank you for your time.

I'm not 100% sure, but you can try to set the ABI version to 50.
export npm_config_abi=50

[jhen0409]

I remember electron-rebuild is only for node-gyp rebuild (binding.gyp), looks like fastcall is using cmake-js for build, so you may refer to cmake-js usage.

Change to: (install script in package.json of node_modules/fastcall)

    "install": "cmake-js compile --runtime=electron --runtime-version=1.4.13",

Then, remove build/ and re-run the script. (it worked for me)

It worked! Thank you very much!

(Didn't test @dustintownsend solution, but thanks anyway!)

I believe I found a better solution to my problem.

Adding this to app/package.json will solve all ABI problems with packages that rely on cmake-js to build themselves:

  "cmake-js": {
    "runtime": "electron",
    "runtimeVersion": "1.4.13"
  }

If only someone knew how to fill automatically the runtime version of electron...

I still get this error:
