Compile error

[iavian]

I am trying to compile a code that includes header from both oracle
and postgres

/usr/local/pgsql/include/server/c.h:420: error: conflicting
declaration 'typedef struct varlena text'
/opt/oracle/product/10.2.0/rdbms/public/oratypes.h:196: error: 'text'
has a previous declaration as `typedef oratext text'

How do i fix this ?

Best not to try: Keep the two conflicting headers apart
from each other by compiling the Oracle- and Postgres-using
parts of the program in separate modules.

But if you *must* try to force two square pegs into the
same round hole, you *might* be able to do something like

#define text vtext
#include "c.h" /* the "struct varlena" one */
#undef text

#define text otext
#include "oratypes.h " /* the "oratext" one */
#undef text

.... and then use "vtext" and "otext" throughout the rest of
the code. No guarantees that this will work, though: much
depends on what else these headers may be doing.

There may be further troubles awaiting you if you get
past the compilation errors, if the libraries that accompany
these headers contain external definitions that clash. For
example, if each defines its own connectToDataba se() function
your compilation difficulties will be only the beginning ...
