[BangPypers] Python 2.7.1 build successful, however many modules failed on HP-UX 11.31 ia64 with aCC

[Wah Meng Wong]

Hello there,

I am trying to build python 64-bit on HP Itanium platform with HP-UX Ansi C compiler. The python executable is successfully built however there are many errors generated when option +DD64 is passed in, many (more) modules failed to build (compared to 32-bit option is used).  


I followed the instruction in README file to set and unset the enviornment variables like CC, CXX, LDFLAGS and BASECFLAGS like below, and remove Optimization option in the Makefile, however, many modules failed to build. There are warning messages on the compilation which I can ignore, however, there are fatal errors that "+DD64" is not a recognized flag in the linking process, with command ld.

export CC=cc
export CXX=aCC
export BASECFLAGS="+DD64"
export LDFLAGS="+DD64 -lxnet"


# 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 

Messages showing the linking process failed. I am not sure why the ld command cannot accept the flag while the Makefile contains this option when it is generated by "./configure --without-gcc" command with 64-bit options enabled.  


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/math.so
ld: Unrecognized argument: +DD64
Fatal error.

Here is the summary output of the build. I don't think I can use this python executable, so many important modules that I use failed to build. Compared to 32-bit build, I only have 2 modules .

Python build finished, but the necessary bits to build these modules were not found:
_bsddb             _curses            _curses_panel   
_sqlite3           _ssl               _tkinter        
bsddb185           bz2                dl

sunaudiodev        zlib                               
To find the necessary bits, look in setup.py in detect_modules() for the module's name.

Appreciate any input on this issue when 64-bit option is passed into aCC that cause so many errors on my server. Thanks!
