Thanks for this new iteration. However, it's a pity that you didn't
reuse any of the improvements I had, and which I suggested you to
re-use for your next iteration.

So, I redid the same changes, and also improved the description of
0001-target-build-using-host-plugin.patch which was really not
sufficient.

Here is the list of changes I did:

    [Thomas:
     - add missing Config.in dependencies inherited from
       BR2_PACKAGE_PROTOBUF, as well as the corresponding Config.in
       comment
     - replace spaces by tabs in grpc.mk indentation
     - remove superfluous GRPC_SOURCE variable
     - improved patch description.]

After those changes, I applied this patch to next. Thanks for your
contribution!

Thomas

Itr also seems that grpc would somehow need gflags:

    CMake Warning at cmake/gflags.cmake:26 (message):
      gRPC_GFLAGS_PROVIDER is "module" but GFLAGS_ROOT_DIR is wrong

That's because the built-in copy of gflags is missing (good!) as it is
managed by a git submodule, and those are not retrieved when using the
github macro (good!). So, maybe extend HOST_GRPC_CONF_OPTS with:

    gRPC_GFLAGS_PROVIDER=none

Alternatively, you could make the existing gflags package a host
package, and use that?

Additionally, there is a similar issue with the 'benchmark' package:

    CMake Warning at cmake/benchmark.cmake:26 (message):
      gRPC_BENCHMARK_PROVIDER is "module" but BENCHMARK_ROOT_DIR is wrong

We don't have a benchmark package in Buildroot, so maybe extend
HOST_GRPC_CONF_OPTS with:

    gRPC_BENCHMARK_PROVIDER=none

Note that thes two issues should probably be also checked for, and fixed
for the target variant of grpc too.

Finally, we do have a bunch of autobuild failures:

    http://autobuild.buildroot.org/?reason=host-grpc-v1.16.1

Care to have a look, please?

Regards,
Yann E. MORIN.

I was able to reproduce this in a non-sandboxed environment and it
looks like the "grpc_cpp_plugin" app is outputting that error, not the
'protoc' part of the command.

Output
----------------------
terminate called after throwing an instance of 'std::system_error'
  what():  Unknown error -1
Aborted (core dumped)

A quick strace and gdb run didn't get me much further.  It looks like
the libstdc++ is maybe having a memory allocation issue but I'll have
to work on getting more debug symbols (sort of a messy point to debug
when between host machine and buildroot host package builds).

Applied to next after extending the commit log, and re-adding Arnout
