xerces 2.8.0 runConfigure fail on AIX 5.3.0 (xlc_r version issue)

Hi All

and thanks in advance.

this is urgent to us.

OS:
      AIX 5.3.0
Compiler:
      IBM XL C/C++ Enterprise Edition V8.0 for AIX
      Version: 08.00.0000.0020

we execute runConfigure:
./runConfigure -paix -cxlc_r -xxlC_r -z-+ -z-qnamemangling=v5 -z-G
-z-qmkshrobj

result:

Generating makefiles with the following options ...
Platform: aix
C Compiler: xlc_r
C++ Compiler: xlC_r
Message Loader: inmem
Net Accessor: socket
Transcoder: native
Thread option: pthread
Library type: shared
bitsToBuild option: 32
Extra compile options:  -+ -qnamemangling=v5 -G -qmkshrobj
Extra link options:
Extra configure options:
Debug is OFF
Found host system to be powerpc-ibm-aix5.3.0.0

checking for gcc... xlc_r
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.

"config.log" result:

....

## ----------- ##
## Core tests. ##
## ----------- ##

configure:1765: checking for gcc
configure:1792: result: xlc_r
configure:2030: checking for C compiler version
configure:2037: xlc_r --version >&5
xlc_r: 1501-216 command option --version is not recognized - passed to ld



  xlc(1)                 IBM (October 2005)                  xlc(1)


Summery:
it seems like there is a version query issue.

is there a workaround for that ?

Thanks

No, it's an issue with xlC and the AIX linker.

The .a file is a library with shared objects in it. Shared objects on 
AIX are much like Windows DLLs, in that there is no run-time linking 
like ELF platforms support.

There is a mode that somewhat emulates run-time linking, but it's 
unlikely you need it. Such shared objects can have the .so extension, to 
distinguish them from standard shared objects.

Hi all

removing -z-G -z-qmkshrob runConfigure successfully.

./runConfigure -paix -cxlc_r -xxlC_r -z-+ -z-qnamemangling=v5
Works ok

We do get tones off duplicate symbols, is there a way to avoid that ?

Is there a way to make to link as *.so and not dot *.a ?

this what we where trying to do with "-z-G -z-qmkshrob"
