electron-builder: Linux build fails at icon conversion

Building a deb with the latest release (2.9.5) I get the following error:

Unhandled rejection Error: Command failed: gm convert: Unable to open file (/tmp/electron-builder-30935NzzLT2KzUll7/icon_128x128x32.png) [No such file or directory].

I have provided a build/icon.icns file (generated using these steps: http://blog.macsales.com/28492-create-your-own-custom-icons-in-10-7-5-or-later). When I look what’s in the /tmp/electron-builder-30935NzzLT2KzUll7/ folder, I see that it created the following icons:

icon_16x16x32.png
icon_256x256x32.png
icon_32x32x32.png
icon_512x512x32.png

Looks like 64 and 128 is missing.

I am building the linux deb from an Ubuntu 15.10 machine.

Any ideas what’s going on? Alternatively, could I just provide the icons “manually” (I already have all those pngs anyways)?

AppImage target will be set as a default target Linux soon (once all known AppImage issues will be solved) — I decided to to bump major version to 6 and don’t wait NSIS auto-update feature. Because AppImage is better than deb and electron-builder should promote it.

@JimiC develar had an example where he named the png files in build/icons folder to be

24x24.png
32x32.png
48x48.png
64x64.png
128x128.png
256x256.png

And it worked for me after trying that, if you’re just trying to get something up and running. Of course you can always just specify an icon.icns file in your build.osx options, which should be located in the build folder, and the linux build will pick it up.

not picking up the icon path from the osx build options

It is DMG icon “which will be shown when mounted”. Yeah, it is not user-friendly and confusing.

Thanks. And to clarify, what I had trouble with was the Linux build not picking up the icon path from the osx build options. And also, the Linux build would only work if my icon file was called build/icon.icns
