Compiled binaries downloaded by mksnapshot broken?

[ghost]

Looks like mksnapshot compiled binaries downloaded by electron-mksnapshot wrong compiled. When I downloading prebuilt binaries for arm/armv7l I got Intel 80836 binaries.
file mksnapshot output:
mksnapshot: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=8b1a63cf158c934666279b6539cfa945502264c5, not stripped

So, I'd like to compile mksnapshot separately from Electron on my machine, where i can found sources for it?

Any news? :(

@hypersad which version of mksnapshot and electron are you using?

[ghost]

@kewinsawicki I need mksnapshot for building Atom. Defined electronVersion to 1.6.0 and mksnapshot to ~1.6 in package.json.

[kevinsawicki]

@hypersad can you try setting running:

npm --arch=armv7l --platform=linux install electron-mksnapshot@1.6.0

and see if that downloads the right version?

I'll try it when i come home, but didn't think that it help me, because I tried some versions from china mirror and they returns Intel 80836

Still getting Intel 80836 binaries...
Install log can be found here

[kevinsawicki]

@hypersad can you download https://github.com/electron/electron/releases/download/v1.6.0/mksnapshot-v1.6.0-linux-armv7l.zip directly and confirm it works as expected?

Again Intel 80836, again 'Exec format error'...

Any news? We need mksnapshot for trying to build Atom on armv7l :(

[ghost]

Maybe I should create an issue in electron?

[mathuin]

@hypersad I made an issue electron/electron#11413 because I didn't know mksnapshot had its own repository. This problem has not yet been fixed, and now your unmaintained repository no longer builds -- not your fault, that's what unmaintained means. :-) I am hopeful that whoever does maintain mksnapshot can somehow get it to build for ARM now that electron-packager supports ARM, because I think that's the last roadblock preventing master-branch Atom from being compiled for armv7l.

@jkleinsc is actively working on resolving the mksnapshot issue, and I believe he cut a new release today.

[mathuin]

I find that very exciting! What can I do to test it?

[jkleinsc]

Starting with version 1.8.5 (as well as 2.0.0-beta7), we changed how we distribute the arm/arm64 binaries of mksnapshot. There are now 4 files for arm/arm64 mksnapshot, for example the following from the 2.0.0 release:

• mksnapshot-v2.0.0-linux-arm-x64.zip - intel x64 binary that produces snapshots suitable for using on armv7 hardware.
• mksnapshot-v2.0.0-linux-arm.zip - armv7 binary that produces snapshots suitable for using on armv7 hardware.
• mksnapshot-v2.0.0-linux-arm64-x64.zip - intel x64 binary that produces snapshots suitable for using on armv8(arm64) hardware.
• mksnapshot-v2.0.0-linux-arm64.zip -armv8(arm64) binary that produces snapshots suitable for using on armv8(arm64) hardware.

Because of these changes, when you now run npm install with an electron-mksnapshot dependency on arm or arm64 hardware you will get the binary that can actually run on those platforms.
