Re: [cx-oracle-users] Trouble compiling on Linux / Python 2.3.4

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

You are compiling DCOracle2, right? If so, you've come to the wrong 
list... :-) I think the Zope guys deal with this stuff so you can ask 
them about these problems. I can give you a hint about the problem, 
though. The last error is simply telling you that it can't find the 
symbols referenced in the C source. From experience they are the Python 
libraries and the OCI (Oracle) libraries. BUT, the removal of the -c 
option is the real problem since clearly the Makefile is trying to 
simply compile the source into an object file for __later__ linking. I'm 
not sure what the @DEFS@ is for but I would guess that autoconf was 
supposed to replace that with something real. Good question on that one, 
though. Try removing the @DEFS@ from the original command line and see 
if that solves your problem. Anything else though should go to somewhere 
else. Now if you want to try cx_Oracle and you run into troubles there, 
I'd be more than happy to help! :-)
