[Python-sybase-misc] 64-bit sybase libraries

[Gnepp, A. <And...@de...>]

Hi,
In revision 405, setup.py was changed to default to the non-thread-safe Sybase libraries under 32-bit compilation.  However, 64-bit compilation still defaults to the thread-safe ones (with "_r" in the name).
   91         extensions = [('', 'a'), ('', 'so'), ('_r', 'a'), ('_r', 'so')]
   92         if have64bit and sys.platform not in ['osf1V5']:
   93             extensions = [('_r64', 'a'), ('_r64', 'so')] + extensions
Is this discrepancy between 32- and 64-bit intentional, or can 64-bit compilation also default to the non-thread-safe libraries when available?
i.e. something like:
   93             extensions = [('64', 'a'), ('64', 'so'), ('_r64', 'a'), ('_r64', 'so')] + extensions

Hi Andrei,

I think you are right it would be more consistent to also prefer the 
mono-threaded libraries on 64 bits architectures.

I will make the modification you suggested.

On the other hand, it would be even better if we could specify with a 
compilation flag to setup.py the preferred way to compile: 
static/dynamic - threaded/non-threaded.

I will try to see if such options can be added, with a lower priority.

regards
