Re: [cx-oracle-users] Some build problems of cx_Oracle 4.1 beta1 on Win32

[Anthony T. <an...@co...>]

I've never built cx_Oracle on Windows using the VC++ compilers. I've 
always used gcc (http://www.mingw.org). That way the options are the 
same on all of the platforms. Distuils handles most but not all of these 
issues -- as you can see. Do you have to use VC++ or can you use the 
binaries or mingw?

BTW, gcc allows linking directly to a DLL so I have never bothered to 
build or use an import library. Thus the requirement for win32api solely 
so that I can discover the Python DLL to link against. Its unfortunate 
that distutils or Python itself doesn't provide this information. Its 
also unfortunate that VC++ doesn't provide this capability.
