[jira] Created: (XERCESC-1929) Build configure script choose the wrong transcoding service on HP-UX

Build configure script choose the wrong transcoding service on HP-UX
--------------------------------------------------------------------

                 Key: XERCESC-1929
                 URL: https://issues.apache.org/jira/browse/XERCESC-1929
             Project: Xerces-C++
          Issue Type: Bug
          Components: Build
    Affects Versions: 3.1.0
         Environment: 2 Intel(R) Itanium 2 9000 series processors (1.6 GHz, 18 MB), 16363MB,64bit
HP-UX, 11.23, aCC, A.06.12
            Reporter: yingcai
            Priority: Minor
             Fix For: 3.0.1


On our HP-UX, Xerces-C 3.1.0 uses GNU iconv lib by default, but that library does not exist. So it leads to an "can not load transcoding service" error. I think need to check the following part of Xerces-C 3.1.0's m4/xerces_transcoder_selection.m4. 

       # Check for GNU iconv support
       no_GUNiconv=false
       AC_CHECK_HEADERS([iconv.h wchar.h string.h stdlib.h stdio.h ctype.h locale.h errno.h], [], [no_GNUiconv=true])
         # The code in iconv needs just on of these include files
       AC_CHECK_HEADER([endian.h],
                         [],
                         [
                          AC_CHECK_HEADER([machine/endian.h],
                                          [],
                                          [
                                           AC_CHECK_HEADER([arpa/nameser_compat.h],
                                                           [],
                                                           [no_GNUiconv=true])
                                          ])
                         ])

On our HP-UX, endian.h or machine/endian.h doesn't exist, but arpa/nameser_compact.h exists, so the configure script thinks that GNU iconv library exists.

In Xerces-C 3.0.1  GUNIconv lib detection m4 definition is like this:

       AC_CHECK_HEADERS([iconv.h wchar.h string.h stdlib.h stdio.h ctype.h locale.h errno.h endian.h], [], [no_GNUiconv=true])

It doesn't check arpa/nameser_compact.h or machine/endian.h. 

This problem can be solved by passing "--enable-transcoder-iconv" to configure.
