Hi,
i am trying to add some functions to postgresql.
I created a file called "...../src/backend/executor/testing.c"
then created a file called "...../src/include/executor/testing.h"
then added "testing.o" to the OBJS in "...../src/backend/executor/Makefile"
I included "executor/testing.h" in execMain.c, and from there, I tried to
make a function call to function which is in testing.c
When I tried to gmake, i got the following error message:
********************************************************
Undefined first referencedsymbol in file
PrintPlan executor/SUBSYS.o
PrintQuery executor/SUBSYS.o
ld: fatal: Symbol referencing errors. No output written to postgres
********************************************************
this is an error during the linking.
Any idea what i am missing?
thanks,
--h
