             Summary: Swig generated c code for java bindings fails to compile on Windows Visual Studio 2010
                 Key: PROTON-254
                 URL: https://issues.apache.org/jira/browse/PROTON-254
             Project: Qpid Proton
          Issue Type: Bug
          Components: proton-c
    Affects Versions: 0.4
         Environment: Windows 7
Visual Studio 2010
            Reporter: Keith Wall


Swig generated C code for the Java bindings fails to compile on Visual Studio 2010 with error message:

C1083: Cannot open include file: 'stdbool.h': No such file or directory

After discussion on list [1], we tried changing bindings/java/CMakeLists.txt to use CPLUSPLUS ON directirve to CMake in the case where BUILD_WITH_CXX has been enabled eariler in the build.

if (BUILD_WITH_CXX)
     SET_SOURCE_FILES_PROPERTIES(python.i PROPERTIES CPLUSPLUS ON)
  endif (BUILD_WITH_CXX)

Switching to CPP in this way exposed a number of errors when compiling the CPP code resulting from the java.i (casting issues, pointer arithemetic etc).  However, even after resolving the CPP compilation issues, we then encounter a problem with Swig's handling of nested unions when when CPP.  The seeming inability of SWIG (when used with CPP) to represent the union means that SWIG does not produce pn_atom_t_u.java, and subsequently, JNIMessage.java fails to compile.
