[PyQt] HP-UX, SIP, Python, g++ problems

[Bill Jester]

Hello all,
   I have a large, C++ module which we compile successfully on 64 bit 
HP-UX PA-RISC using the gnu4.1 compiler.   Switching to the aCC compiler 
on this platform is not an option because we are pushing the envelope a 
bit on template metaprogramming and have little success with system 
compilers.
   I am attempting to bind a portion of our product to Python via SIP 
but am having nothing but trouble on this platform (all went well the 
first time on Linux).    The problems I'm having are summarized below:

1) "make install" for Python failed on this OS -- when compiling 
test_multibytecodec.py I get:

Compiling 
/u/edge01/soft/jester/tools/python/hp8/lib/python2.5/test/test_multibytecodec.py 
...
Sorry: UnicodeError: ("\\N escapes not supported (can't load unicodedata 
module)",)

... I had to hack the makefile for it to proceed beyond this so it was 
not a showstopper...

2) Once I worked around this I managed to compile SIP with the same 
compiler used for Python and our product (gnu4.1.1).    When I try to 
import our module, however, I get pages of errors:

/usr/lib/pa20_64/dld.sl: Unsatisfied code symbol '__cxa_finalize' in 
load module 
'/u/edge01/soft/jester/tools/python/hp8/lib/python2.5/site-packages/sip.sl'. 


... for sip.sl and pretty much every other library in the module, 
including the libgcc_s system libs. 

3) If I stub out __cxa_finalize (seems dangerous) I can successfully 
import the module.   When I try to actually use it, however, I get:

error loading libParasolid.sl :  '/lib/pa20_64/libcl.2' contains a 
static TLS reference to '__thread_specific_seg' defined in a dynamically 
loaded library '/lib/pa20_64/libcl.2'. Use +tls=dynamic to re-compile 
'/lib/pa20_64/libcl.2'.

Am I trying to do something impossible here by mixing gcc, Python, SIP, 
and C++ on an HP machine?   The full spec for the machine is listed below.

Thanks in advance for any help,
Bill Jester
