Re: [Firebird-odbc-devel] ODBC driver on 64-bit linux

[Bill G. <bg...@co...>]

Hi Dmitry,

Thanks for taking a look at this.

I guess I gave the wrong impression with my post. I don't have any 
problem building the
driver-- only when I try to use it. Specifically, I get an error at 
execution time when I do a simple test
that tries to insert two integer fields into a relation. I'll try to 
clean up my example and post it.

As for -DSIZEOF_LONG=8, I think that *is* being defined but is not 
necessarily required to
be defined in makefile.linux. Here is what I mean. If I look at the top 
of /usr/include/sqltypes.h,
on my Redhat system, I see these lines.

#ifndef SIZEOF_LONG
# if defined(__alpha) || defined(__sparcv9) || defined(__LP64__) || 
(defined(__HOS_AIX__) && defined(_LP64))
# define SIZEOF_LONG        8
#else
# define SIZEOF_LONG        4
#endif
#endif

With g++ -m64, __LP64__ is automatically defined so SIZEOF_LONG        8 
is also defined

SIZEOF_LONG ==8 insures that SQLINTEGER is a 4-byte quantity.
