Обсуждение: undefined reference to crypt
Hi,
I am discovering PostGreSQL and Linux.
I have a little problem with libpq.
Here is my C program (it's empty!)
/* --------- essai.c -------------------------- */
#include <stdio.h>
#include "/usr/lib/pgsql/include/libpq-fe.h"
int main(void)
{
}
/* ------------------------------------------- */
Here is my makefile:
essai.o: essai.c
gcc -c essai.c
essai: essai.o
gcc -o essai essai.o -lpq
When I do "make essai", the following error appears:
/usr/lib/libpq.so: undefined reference to crypt.
collect2: ld retruned 1 exit status
I suppose a file/library is missing.
Can you help me?
The postgres' programmer guide refers to several examples in
/src/test/regress.
These samples are not installed with my postgres distribution .
Where can I download them (or other examples?).
Sorry for my poor english and thank you for your answers,

Go to www.postgresql.org and download the source distribution. The examples are in there. ->->->->->->->->->->->->->->->->->->---<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-< James Thompson 138 Cardwell Hall Manhattan, Ks 66506 785-532-0561 Kansas State University Department of Mathematics ->->->->->->->->->->->->->->->->->->---<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<
