[BUG] Compilation of Protox 1.6 fails about protox

[sneako]

The include_well_known_types branch works for me!

Thanks for the report! The funny thing is that I cannot reproduce this 😬. But the message returned by protoc might give a hint: \ngoogle/protobuf/any.proto: File not found.
I think it means that not all protoc installations come with well-known types 🤔. Out of curiosity, how did you install protoc (and on which OS) ?

I guess I have to add the definitions of these types manually. I was reluctant to do this at first, but it seems other implementations had to do this (for instance: go).

Could you try with the include_well_known_types branch? It should fix this bug as now well-known types proto files are embedded in protox.

Interesting! Maybe this has something to do with how I installed protoc? I encountered this error first on my Fedora workstation, but I just tried on my Macbook and I do not get the error there. I think I just grabbed the binary from their github releases page on both workstations...

I'll try out that branch right now!

Just for a bit more information, in my application's dockerfile, which is based on hexpm/elixir:1.12.3-erlang-24.0.6-ubuntu-focal-20210325 and I install protoc from https://github.com/protocolbuffers/protobuf/releases/download/v3.15.5/protoc-3.15.5-linux-x86_64.zip, I can reproduce the error as well when trying the released 1.6 version.

Thank you! I'll release 1.6.1 right away to fix this.

BTW, looking at the readme.txt file in the archive you referenced, it says:

If you intend to use the included well known types then don't forget to
copy the contents of the 'include' directory somewhere as well, for example
into '/usr/local/include/'.

So I guess that some package managers don't perform this step.
