Обсуждение: Problems compiling test program program form pgsql

you're missing an install of the crypt library, which seems kind of odd,
since i thought that was a standard part

look in /usr/lib

you should have two files and one symbolic link:

 /usr/lib % dir libcry*
-rw-r--r--   1 root     root        98012 Sep 20  1999 libcrypt.a
lrwxrwxrwx   1 root     root           23 Sep 19  1998 libcrypt.so ->../../lib/libcrypt.so.1
-rw-r--r--   1 root     root        98908 Sep 20  1999 libcrypt_p.a

I believe that if you add a '-l' option to your compile command it will
work:

<To your presend command add>  -lcrypt

Hi Hugh, it looks like -l must have worked. I use that when I need the
math libs.
