1541112 - "mach bootstrap" for android build on macOS is failing

Status: RESOLVED DUPLICATE of bug 1540788

(Firefox Build System :: Bootstrap Configuration, defect)

Description

[Jonathan Kew [:jfkthame]]

Trying to update build environment to do a local Android build. Result:

$ ./mach bootstrap

Note on Artifact Mode:

Artifact builds download prebuilt C++ components rather than building
them locally. Artifact builds are faster!

Artifact builds are recommended for people working on Firefox or
Firefox for Android frontends, or the GeckoView Java API. They are unsuitable
for those working on C++ code. For more information see:
https://developer.mozilla.org/en-US/docs/Artifact_builds.

Please choose the version of Firefox you want to build:
  1. Firefox for Desktop Artifact Mode
  2. Firefox for Desktop
  3. GeckoView/Firefox for Android Artifact Mode
  4. GeckoView/Firefox for Android
Your choice: 4

Error running mach:

    ['bootstrap']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.

You should consider filing a bug for this issue.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

Comment 1

[Jonathan Kew [:jfkthame]]

FTR, in #developers Nathan suggested

<froydnj> jfkthame: you could try explicitly running rustup update && rustup target add thumbv7neon-linux-androideabi to see if that fixes anything

After running this, ./mach bootstrap completes happily.

Ah, this was bug 1540788. Doh.
