It seems your protoc version is too old. Could you please try to remove the old version and install the latest one?
You can double check by running protoc --version, 3.6.0 or above is required.

i tried protoc --version -> libprotoc 3.7.0

still a problem:

@yoshi721 what OS are you running?

I got the same issue with Mac OS X 10.14.5 (18F132).

It seems that I need to uninstall proto2 and re-install proto3. Reference: linkerd/linkerd#1118

I'll post here if this can be fixed with the above reference.

[ruig2]

The issue is that the default version of protobuf in brew is 2.x: https://github.com/libra/libra/blob/master/scripts/dev_setup.sh#L141, while we need a 3.x to make things working.

If you get the same issue, let's uninstall protobuf 2.x and install a protobuf 3.x:

brew uninstall protobuf --force # delete 2.x
brew install protobuf@3.6 # install 3.x
protoc --version # it should now show libprotoc 3.6.1

Then re-run the scripts (https://developers.libra.org/docs/my-first-transaction) to make Libra working.

@yoshi721 work for me https://medium.com/coinmonks/libra-digitalocean-8083326bb266

@yoshi721 Hi, I have the same problem and I found the solution. You just need to download the protoc (like protoc 3.9.0 from https://github.com/protocolbuffers/protobuf/releases), and copy the include directory to /usr/local.

Just installed protoc 3.6.1 didnt work for me.

I am using Mac OS 10.15.1 ver and do not have an issue with the execution of ./scripts/cli/start_cli_testnet.sh.

have you downloaded the latest one and execute the same?

The external dependencies needed to build Libra have been simplified and should only require Rust now so this shouldn't be an issue anymore on master. If it is, please let us know.
