unable to make on ubuntu 17.04 about grpc-c HOT 11 OPEN

"error: ‘map’ does not name a type" Do you have build essentials installed? Can you build https://github.com/protobuf-c/protobuf-c project and see if that goes through fine?

from grpc-c.

@ajhai protobuf-c is already installed and able to do the example snippet compilation. i.e, protoc --c_out=. example.proto What I am trying to achieve is building a c based server stram application.

I took a look and that is a legitimate error. That header file includes and declares a variable "variables_" of type map...which it should be std::map. So it's a legitimate bug IMO. Its possible for the developer that header includes somewhere in the chain have a "using namespace std;" in which case the map without std:: prefix would work...but that would be bad form. Dont use "using namespace ..." in headers (impl files are fine). Reason being that it imports the entire std:: namespace into global namespace, can then cause naming conflicts, it's affect is viral to all code that includes that evil header, and negates the whole reason for using namespaces. My suggestion would be to fork that project and fix up those issues by adding std:: to the front of map. Then send the original developer a pull request after you have it working.

@guru-florida Thanks for looking into it. Like I said, the namespace issue keeps growing for other components like sets, queue and so on. So I thought I was missing something. So were you able to compile this in other environments?

from grpc-c.

I found these are already addressed in the parent protobuf-c so updated the submodule by pulling from the master for the submodule. Now I am having this issue. @ajhai Anything that I missed here ?

@javapriyan Thanks for identifying protobuf-c updates. I will pull and update submodule. This all seems to be working fine in my vagrant which is Ubuntu 16.04. For the issues that you are seeing now, what is the version of gRPC you have installed? Latest master of grpc-c will work with gRPC v1.3.0

from grpc-c.

@ajhai It was 1.6 I guess. To be precise used this https://github.com/grpc/grpc/blob/v1.6.x/INSTALL.md Let me try downgrade this to 1.3 once.

from grpc-c.

After degrading, I have got this error. I know I am making some noice here but would really love to get this up and running.

Looks like some issue with strndup definition. Other projects also seem to have hit similar issue. Can you check what is the generated value of HAVE_STRNDUP ? Can you paste your configure output? If you want to get it up and running quick, can you try this on a vagrant with 16.04? Use protobuf 3.0 and gRPCv1.3. I suspect the initial error could be because of running latest protobuf. What is the version of protobuf you have installed?

from grpc-c.

I fixed the error: expected identifier or ‘(’ before ‘__extension__’ error by #including "config.h" in lib/stream_ops.c.

@javapriyan Do you have solve the compile problem? How to solve?
