Protobuf: build only c++ (protoc)

[ekg]

Is there a way to only build protoc, not the java or python systems?

Follow instructions here to build protoc (and also proto C++ runtime):
https://github.com/google/protobuf/blob/master/README.md

The above Readme specified in the link builds protoc with all the java and other language compilers, along with c++.
Is there any way to just build protoc cpp compiler?

[DavidRobb]

Actually, build instructions say:

For example: if you only need C++, download protobuf-cpp-[VERSION].tar.gz; if you need C++ and Java, download protobuf-java-[VERSION].tar.gz (every package contains C++ source already); if you need C++ and multiple other languages, download protobuf-all-[VERSION].tar.gz.

Is there any insight into how the protobuf-cpp-[VERSION].tar.gz is constructed?

[acozzette]

@sciencemanx If I remember right that comes from running make dist and then the post_process_dist.sh script.

I answered to my own question on stackoverflow about how to do this. Even though it is quite a rudimentary solution (grep + remove), it does work and compile quite faster. Check the link

@xfxyjwf why is this issue closed?

Following the exact instructions from your link will still build for all languages, not just C++
