The easiest way to do this is to use the customize script in

You *must* set the following variables:

If you have installed the GNU install program (ginstall), you

If you are using an ELF version of Linux, this can safely be

You can correct this by editing

warning: cast from pointer to integer of different size
These can safely be ignored
These were seen in earlier versions of Postgres95 and could
safely be ignored. PostgreSQL V6.0 should compile with no warnings
except those related to system header files (which can also
be safely ignored).

SuSE-Linux has ncurses but not curses. Edit src/bin/psql/Makefile and
Change

SuSE-Linux has ncurses but not curses. Set the value of CURSES_LIB

to:

In fact, since ncurses uses terminfo rather than termcap, it should
be possible to change this line to
LD_ADD +=
since you shouldn't need the termcap library.

This was a problem in earlier versions of Postgres95. The default
for PostgreSQL is to use bison -y rather than yacc.
yacc is generally implemented as a script which invokes bison -y
For some reason (certain versions of make? certain versions of
bash?) make is unable to execute this script file.
