The .pb.h file compares the version of protoc that generated it against GOOGLE_PROTOBUF_MIN_PROTOC_VERSION, which is #defined in google/protobuf/stubs/common.h. We have never released a version in which this value was more than 2003000, which corresponds to protoc 2.3.0, so I can't imagine why you're getting the error. Please investigate yourself and let us know if you figure it out.
BTW, there's a good chance that "pkg-config --cflags --libs protobuf" is not producing the correct flags since you did not install to the standard location (pkg-config probably does not know to look in /meda/EXTDIV for package definitions). However, even so, I don't understand why you'd get the error you're getting. On Wed, Feb 3, 2010 at 11:12 AM, hap 497 <hap...@gmail.com> wrote: > Thanks.
