Re: how to add my source file?

Sorry I did not want to bother you with the details, I just thought that there is smth that I have to do apart from
addingthe object file name into the Makefile.<br /><br />So, here is the whole picture:<br /><br /><br />I want to
writea function that takes the raw parsetree and rewrites it according to my rules, then produce new raw parsetrees.<br
/><br/>I will call this function inside backend/tcop/postgres.c . I wrote an header file called my_rewriter.h and
includethis inside postgres.c.<br /><br />my_writer.h looks like:<br
/>-------------------------------------------------<br/>#ifndef UWSDREWRITE_H<br />#define UWSDREWRITE_H<br /><br
/>#include"nodes/pg_list.h"<br />#include "nodes/nodes.h"<br /><br />typedef struct my_Projection<br />{<br />    char
*relname;<br/>    List attnames;<br />    char *result_relname;<br /><br />} my_Projection;<br /><br />.<br />.<br
/>.<br/><br />extern void  my_analyze(Node *parsetree);<br />extern void my_rewrite(List *parsetree_list);<br /><br
/>#endifUWSDREWRITE_H<br />---------------------------------------------<br /><br /><br />my_writer.c looks like:<br
/>-------------------------------------------------<br/>#include "nodes/nodes.h"<br />#include <stdio.h><br
/>#include"nodes/pg_list.h"<br /><br /><br />static void my_string_print(char *s);<br />static void my_int_print(int
i);<br/><br />static void my_string_print(char *s)<br />{<br />    FILE *outfile = fopen("/home/?/the_log.txt",
"a");<br/>    fprintf(outfile,"\n%s\n", s);<br />    fflush(stdout);<br />    fclose(outfile);<br />}<br /><br />static
voidmy_int_print(int i)<br />{<br />    FILE *outfile = fopen("/home/?/the_log.txt", "a");<br />    fprintf(outfile,"\n
theint is: %d\n", i);<br />    fflush(stdout);<br />    fclose(outfile);<br />}<br /><br />void UWSD_rewrite(List
*parsetree_list)<br/>{<br />    ListCell   *parsetree_item;<br />    <br />    foreach(parsetree_item,
parsetree_list)<br/>    {<br />        Node       *parsetree = (Node *) lfirst(parsetree_item);<br />       
UWSD_analyze(parsetree);<br/>    }<br />}<br /><br />void UWSD_analyze(Node *parsetree)<br />{<br />   
if(nodeTag(parsetree)==T_SelectStmt)<br/>    {<br />        my_string_print("THIS IS A SELECT STMT");<br />    }<br
/>   else my_int_print(nodeTag(parsetree));<br />}<br /><br
/>-----------------------------------------------------------<br/><br /><br />Then I wrote a C file called my_writer.c,
anddo the implementation of my_analyze(Node *parsetree) and my_rewrite(List *parsetree_list) functions.  I need Node
andList 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:<br /><br />---------------------------------------<br
/>../../../src/include/nodes/nodes.h:359:error: syntax error before ¡Node¢<br />../../../src/include/nodes/nodes.h:398:
error:syntax error before ¡equal¢<br />../../../src/include/nodes/nodes.h:398: warning: type defaults to ¡int¢ in
declarationof ¡equal¢<br />../../../src/include/nodes/nodes.h:398: warning: data definition has no type or storage
class<br/>----------------------------------------<br /><br />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?<br /><br />regards,<br
