Getting 'protoc not found' error

[vvviiimmm]

Hello,

Trying to use the plugin but getting this error message saying protoc couldn't be found.

[error] (protobuf:protobufGenerate) error occured while compiling protobuf files: Cannot run program "protoc": error=2, No such file or directory

I do have protoc installed in my path:

➜ ~ which protoc
/usr/local/bin/protoc
➜ ~ protoc --version
libprotoc 2.6.1

Not sure if thats an issue, but I did everything from installation guide. Any help would be greatly appreciated.

Sounds like a PATH issue, try setting the path to protoc explicitly in SBT:
PB.protoc in PB.protobufConfig := "/usr/local/bin/protoc"

Alternatively, you can use protoc-jar as explained in "Running without Protoc" at https://trueaccord.github.io/ScalaPB/sbt-settings.html

Thanks a lot, setting the path explicitly helped.

Hi,

Obserning the below error even after installing protobuf 3.1.0
root@ubuntu:/usr/local/bin# protoc --version
-bash: /usr/bin/protoc: No such file or directory

Could you please help?

Hi @samuelpraveen ,

1. It looks like you have problem installing protoc, so it makes sense to ask it at the protobuf mailing list, not ScalaPB. However, if you just did make install and using bash try running rehash and sudo ldconfig if needed.
2. If you are using ScalaPB through sbt-protoc, you don't have to install protoc. Out of the box protoc is provided to you as a dependency.
