protoc-3.0.0-osx-x86_64.exe": error=86, Bad CPU type in executable on Mac M1

[kanstantsin-bucha]

Hi! Help will be very appreciated.
I have the issue on one of my dev's Mac. The full error is

> java.io.IOException: Cannot run program "/Users/aweinzettl/.gradle/caches/modules-2/files-2.1/com.google.protobuf/protoc/3.0.0/31a580cdff228f572e27920c0abcfa71cd3d95e4/protoc-3.0.0-osx-x86_64.exe": error=86, Bad CPU type in executable

I believe that Mac must not run *.exe files. Because it is windows executable.
Mac can run binary files with no extension like protoc-3.0.0-osx-x86_64.

Please provide a glue -

• is protoc-3.0.0-osx-x86_64.exe is the binary that required to be run, and I should remove the extension
• or it is artefact and I should find out a way to remove the step that runs protoc-3.0.0-osx-x86_64 from gradle

I am not very common with the potoc for Android. The issues is very rare because for other devs all fine.

Thank you in advance!

Run file on the binary to see that it isn't a Windows executable. Maven Central requires artifacts to have an extension, so exe was chosen; it could have been bin just as easily.

This issue is unrelated to the gradle plugin. https://github.com/protocolbuffers/protobuf would be the more appropriate location.

Look again at the title: x86_64, Mac M1, Bad CPU type. The problem is trying to run a x86_64 binary on the ARM M1. Newer builds of protobuf have "aarch_64" versions, but they are actually just copies of the x86_64 binaries. See protocolbuffers/protobuf#8557 . To my knowledge, there aren't yet actual ARM builds of protoc available yet, but you can use the current builds with Rosetta without much problem.

@ejona86 Thank you very much!

Seems like this is resolved. If not, comment, and it can be reopened.

The root cause: There was no Rosetta installed on the Mac. It leads to that strange errors.

How to fix: To install Rosetta use Terminal app
softwareupdate --install-rosetta --agree-to-license
