Python 2.7.1 64-bit Build on HP-UX11.31 ia64 with aCC - Manymodules failed to build

Discussion in 'Python' started by Wong Wah Meng-R32813, Sep 18, 2011.

  1. Hello there,

    I have posted this in Compiler SIG and re-post here in case anyone who knows about this issue is not subscribed to that group.

    I am working on python build on my server using HP-UX ANSI C Compiler. I want to be consistent using aCC throughout instead of gcc for my python and cx_Oracle build as Oracle is not supporting gcc build much. Here is my aCC version.

    # swlist -l product | grep Compiler
    ACXX C.06.26.EVAL HP C/aC++ Compiler
    C-ANSI-C C.06.26.EVAL HP C/aC++ Compiler
    COMPLIBS B.11.31 Compiler Support Libraries

    Anyhow, my issue now is when I am building my python in 64-bit, I am encountering many modules failed to build issue, despite the python executable issuccessfully built. There are just so many modules that failed, that I would conclude my build failed. :p

    I followed through the instruction in README file for 64-bit build using HP-UX compiler (--without-gcc option is used in configure). I exported and unexported the environment variables before configure and make is run, respectively. I also removed -O option in the Makefile before running make.

    I have a few questions.

    1.) Why Makefile is re-generated after python executable is created? I noticed the removal of optimization flag in Makefile is gone/restored after python binary is generated.

    2.) 64-bit option. It seems that this is a bad flag that linker doesn't recognize? Many important modules failed to build, and I believe its due to this error. When I manually execute ld without passing in +DD64 flag, the module is generated successfull.

    ld -b +DD64 -lxnet build/temp.hp-ux-B.11.31-ia64-2.7/home/r32813/Build/2.7.1/Python-2.7.1/Modules/mathmodule.o build/temp.hp-ux-B.11.31-ia64-2.7/home/r32813/Build/2.7.1/Python-2.7.1/Modules/_math.o -L/usr/local/lib -lm -o build/lib.hp-ux-B.11.31-ia64-2.7/
    ld: Unrecognized argument: +DD64
    Fatal error.

    Above is just showing one of the modules that failed to build.

    3.) Built in modules, I see the compiler cannot find the bit of informationrequired to build _tkinter module. How do I make the configure able to locate my tcl/tk source code or binary which I have already installed and built separately (and successfully)? So, where do I place the source code if I need to put it so that the compiler can find?

    To end my question, here is the outcome of my build. For build in modules, I just need my _tkinter running. For shared libraries, I think need most of them, those are the basic functions that my application calls.

    Thanks in advance for your reply.

    Python build finished, but the necessary bits to build these modules were not found:
    _bsddb _curses _curses_panel
    _sqlite3 _ssl _tkinter
    bsddb185 bz2 dl
    gdbm imageop linuxaudiodev
    ossaudiodev readline spwd
    sunaudiodev zlib
    To find the necessary bits, look in in detect_modules() for the module's name.

    Failed to build these modules:
    _bisect _codecs_cn _codecs_hk
    _codecs_iso2022 _codecs_jp _codecs_kr
    _codecs_tw _collections _csv
    _ctypes _ctypes_test _elementtree
    _functools _heapq _hotshot
    _io _json _locale
    _lsprof _md5 _multibytecodec
    _multiprocessing _random _sha
    _socket _struct _testcapi
    array audioop binascii
    cmath cPickle crypt
    cStringIO datetime dbm
    fcntl future_builtins grp
    itertools math mmap
    nis operator parser

    Is a 32-bit build faster than a 64-bit build
