I am trying to compile an application developed on SCO Unix with an Ingres
1.2 database that uses embedded sql. I am having a problem with the
included files.
This code appears in the embedded sql in Ingres:
#include <db1.h>
EXEC SQL INCLUDE SQLCA;
EXEC SQL BEGIN DECLARE SECTION;
EXEC SQL INCLUDE '../include/db2.h';
EXEC SQL END DECLARE SECTION;
The ../include/db2.h file contains lines like
typedef char ComText_t[L_COM_TEXT];
that are defined in db1.h
#define L_COM_TEXT 21 /* Length of pvdef text com parameter.
*/
In porting to psql I have
#include <db1.h>
EXEC SQL INCLUDE sqlca;
EXEC SQL BEGIN DECLARE SECTION;
EXEC SQL INCLUDE ../include/db2;
EXEC SQL END DECLARE SECTION;
but receive the error
../include/db2.h:28: ERROR: parse error at or near "L_COM_TEXT"
If I change
typedef char ComText_t[L_COM_TEXT]; to
typedef char ComText_t[21]; /*value of L_COM_TEXT */
everything is fine. Apparently the preprocessing that Ingres did is not
happening in Postgres. There are over 2000 lines in db2.h, mostly with
constants defined in db1.h. Is there something simple I am overlooking, or
an option to epcg that could allow db2.h to be preprocessed before it is
included?
I am a novice at postgres.
