I've been tasked with seeing if we can use protobuf on ucLinux (micro c Linux). We had previously been using an embedded version of Debian Linux and we had protobuf working very well on it.
The specific issue I am having is as I'm building the protobuf code I get this compile error:
google/protobuf/compiler/subprocess.cc:304: error: 'fork' was not declared in this scope
ucLinux does not support 'fork' but it does have 'vfork'. I do not relish the idea of modifying the protobuf source code to change any 'fork' calls to 'vfork' and was wondering if anyone else has "ported" protobuf to ucLinux.
Thanks,
Doug

This is in the protobuf compiler. Do you plan on compiling protobuf
proto definitions into source code on your ucLinux platform itself?

My host platform is an Ubuntu Linux box where the protoc compiler will run to generate the C++ code that will be cross compiled to run on the uClinux target.

So then you don't need the code that's giving you errors - it's part
of protoc. It's been way too many moons since I've looked at the
details for how to only build the lib and not protoc, or even if it's
still possible, but you might find that that's the path of least
resistance.

Ah I see that in the full output of the make process now.
Yes all I really need is to get the libraries built with the cross compiler.
Thank you!

By the way, you may be interested in the nanopb and protobuf-c
implementations, which likely have fewer dependencies.
