Hi,
I want to write a function that takes the raw parsetree and rewrites it
according to my rules, then produce new raw parsetrees.
I will call this function inside backend/tcop/postgres.c . I wrote an header
file called my_rewriter.h and include this inside postgres.c.
my_writer.h looks like:
-------------------------------------------------
#ifndef UWSDREWRITE_H
#define UWSDREWRITE_H
#include "nodes/pg_list.h"
#include "nodes/nodes.h"
typedef struct my_Projection
{
char *relname;
List attnames;
char *result_relname;
} my_Projection;
.
.
.
extern void my_analyze(Node *parsetree);
extern void my_rewrite(List *parsetree_list);
#endif UWSDREWRITE_H
---------------------------------------------
Then I wrote a C file called my_writer.c, and do the implementation of
my_analyze(Node *parsetree) and my_rewrite(List *parsetree_list) functions. I
need Node and List structures here, but when I include the necessary header
files (#include "nodes/pg_list.h", #include "nodes/nodes.h"), I got errors at
compile time like:
---------------------------------------
../../../src/include/nodes/nodes.h:359: error: syntax error before ‘Node’
../../../src/include/nodes/nodes.h:398: error: syntax error before ‘equal’
../../../src/include/nodes/nodes.h:398: warning: type defaults to ‘int’ in
declaration of ‘equal’
../../../src/include/nodes/nodes.h:398: warning: data definition has no type or
storage class
----------------------------------------
So, I think there is a problem with the Makefiles but I do not know what. I
added the object file my_writer.o to the Makefile inside
backend/parser/Makefile and configured again, but it did not work, what else
should I do?
regards,
