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

[Wah Meng Wong]

Thanks Senthil,

1.) Yes compiling and linking with gcc (32-bit) and acc (32-bit) has lesser errors, more modules built successfully compared to acc (64-bit). The main thing I discovered is +DD64 is not recognized as a valid flag in ld command (the linker). This command is automatically generated in Makefile. I have posted my question to bugs.python.org and the community there responded failure to build a module is not a bug and asked me to refer to other community.

2.) The reason I am sticking to acc is, I am also using tcl/tk. I have built tcl/tk with gcc however the tk (wish) crashes with a core dump file generated when gcc is used. Switching to acc, the tk can run without an issue. Also, I need Oracle plug-in in both python and tcl. Oracle only supports HP C Compiler stuffs and not gcc. All these resulted me to focus on acc to get all stuffs done.

3.) Yes I do see cType failed to build when gcc (32) and acc (32) is used. I didn't pursue with python bug community as I don't think I am using either module. What failed to build in 64-bit acc build really worried me. I don't think without those it is usable. ;p. 


(>>>> From make test of acc 32-build and gcc 32-bit build)

Failed to build these modules:
_ctypes            termios                  

4.) Let me try again with --enable-shared and revert. 


Thanks!

You mean to say that python is building properly with all those
modules properly with 32bit compiler and not in 64 bit?
If that is the case, then it surely looks like a bug. You may want to
file open a issue at bugs.python.org

Few pointers.

- Can you use gcc instead of aCC in your machine and see if it can
  build?
- I see at least one open bug with ctypes module not compiling with 64 bit
  HP-UX.
- Try --enable-shared  switch of configure and see if it helps.

If nothing, please do open a bug report and you could get some pointers
from people familiar with that platform.
