[python-sybase] Build runs into problems with sybasect extension

[John C. <jo...@al...>]

Hi Folks,

I'm sure this is just some kind of simple thing, but I am not an 
experienced gcc user and I am quite unsure how to proceed. I'm trying to 
build on Win XP. I've had to tell it to use the cygwin compiler and that 
works, to a point. I do not have the mxDateTime package mentioned in the 
"Prerequisites" section, but it appears that is not absolutely necessary 
(and since I don't need to manipulate datetime values at the moment, I 
was hoping it wouldn't matter).

Do I need the Sybase header files in some include directory (other than 
the one they're in under the Sybase install)? The SYBASE & SYBASE_OCS 
environment variables are properly set.

Any suggestions welcomed. Output of the compiler follows.

John


A bunch of stuff has been built successfully. Using this command:

setup.py build -c mingw32

But, when it gets to this point, I get pages of errors (similar ones are 
omitted and I've put in ... )--some the line-breaks have been changed 
for clarity:
