             Summary: [C, windows] Release 0.16 build fail - src/protocol.h clobbered
                 Key: PROTON-1376
                 URL: https://issues.apache.org/jira/browse/PROTON-1376
             Project: Qpid Proton
          Issue Type: Bug
          Components: proton-c
    Affects Versions: 0.16.0
         Environment: Visual Studio 2012, x64
            Reporter: Chuck Rolke


Target generated_c_files builds the src/protocol.h and src/encodings.h files.
Then projects qpid-proton and qpid-proton-core depend on generated_c_files.

It appears that generated_c_files as a dependency does not respect existing src/protocol.h and src/encodings.h files and generates them three times in total.

On a four-core build system the files are created three times but well before other build threads try to use them. On other systems the timing is such that a compilation of codec.c needs protocol.h but it is erased by the third file creation.
