Unable to run electron app that using node-snap7

[sabinin]

Hi, i was trying to create an simple electron application based on node-snap7 pakage, it works fine under Linux but when i create application for Windows it do not run (when i exclude strings with declaration of variables required for node-snap7 it works on windows too ), can you help to solve this please?

I can try to. What do you mean with

when i exclude strings with declaration of variables required for node-snap7 it works on windows too

Some code would help I think.

var snap7 = require('node-snap7'); var s7client = new snap7.S7Client();

I mean when i just remove this two strings where we declare variables for node-snap7 - then application works on windows. "ERROR_INSTALL_PACKAGE_INVALID 1620 This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package." - this is the error that windows throw when i`m trying to launch application, https://drive.google.com/open?id=0B3ok7GAAR880V2ttRGVUcXNVbnM - here you can find archive with application.

To buid application: npm install ./node_modules/.bin/electron-rebuild

command to build app: electron-packager . --overwrite --asar=true --platform=win32 --arch=x64 --icon=icon.ico To run built aplication you should paste this file to application folder https://drive.google.com/open?id=0B3ok7GAAR880RE4wempBa05VZlk

It is working for me. Are you building the package for windows on linux or windows?

[sabinin]

On linux for windows.

@sabinin , did you have Wine (+1.8) and Mono (+4.2) installed? (see: Multi Platform Build)

[sabinin]

Just Wine, thanks, i`ll try with Mono.

The article posted by @Noctua36 states that cross building is not really possible if you use native packages in your app.

If your app has native dependencies, it can be compiled only on the target platform. prebuild is a solution, but most node modules don't provide prebuilt binaries.

I want to implement prebuild for node-snap7 but I had no time yet.

The easiest solution would be a build server or just a VM.

Thanks, you right, i built it under windows and now it works.

I implemented prebuilts with 0.4.0 just to let you know. Maybe that helps for cross packing electron apps.
