+1.2) What changes do I need to make to src/Makefile.global or
+ src/Makefile.custom?
+
+ The easiest way to do this is to use the customize script in
+ the src directory.
You *must* set the following variables:
PORTNAME= irix5
- IPCSDIR= /usr/sbin
You will also need to change the following to match your own
installation:
- SRCDIR
POSTGRESDIR
If you switch on the USE_TCL option, you will need to set these:
src/Makefile.global?
This was a problem in 1.08 (they are Sun Solaris specific).
- It is fixed in 1.09.
+ It is fixed in 1.09 and above.
1.4) Are there any other changes I should make?
If you have installed the GNU install program (ginstall), you
- should edit src/mk/port/postgres.mk.irix5
- and change the line:
- INSTALL=/usr/bin/X11/bsdinst
- to
- INSTALL=ginstall
+ should add the following line to src/Makefile.custom:
+ CUSTOM_INSTALL=ginstall
For an explanation as to why this is a good idea, see Question 2.1

-1.1) What changes do I need to make to src/Makefile.global
+1.1) What changes do I need to make to src/Makefile.global or

+
+ These changes are most easily made by running the customize
+ shell script in the src directory which will write a
+ Makefile.custom for you.
- You *must* set the following variables:
+ If you do it by hand, you *must* set the following variable:
PORTNAME= linux
You will also need to change the following to match your own
installation:
- SRCDIR
POSTGRESDIR
If you switch on the USE_TCL option, you will need to set these:
1.2) Why do I get problems with missing libreadline?
Linux systems generally don't come with the GNU readline library
- installed. Either comment out the USE_READLINE variable in
- src/Makefile.global or install the GNU readline library.
+ installed. Either ensure you do not activate the readline options
+ in src/Makefile.global or src/Makefile.custom or install the GNU
+ readline library.
Note that Debian Linux (like FreeBSD) does come with readline
installed.
If you are using an ELF version of Linux, this can safely be
ignored as -fPIC is the default.
- You can correct this by editing
- src/mk/port/postgres.mk.linux
+ You can correct this by editing src/Makefile.global and
+ changing CFLAGS_SL
1.7) I get warnings of the form
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).
1.8) [SuSE-Linux 4.2] Where is curses and termcap?
- SuSE-Linux has ncurses but not curses. Edit src/bin/psql/Makefile and
- Change
- LIBCURSES= -lcurses
- to
- LIBCURSES= -lncurses
+ SuSE-Linux has ncurses but not curses. Set the value of CURSES_LIB
+ in src/Makefile.custom to -lncurses (or do this through the
+ customize script).
SuSE-Linux has the termcap library is in /usr/lib/termcap instead of
- in /usr/lib
- Edit src/bin/psql/Makefile and
- Change
+ in /usr/lib. If you have a problem, you need to add the following
+ line to src/Makefile.custom:
+
+ LDADD_BE+= -L/usr/lib/termcap
+
+ You may need to edit src/bin/psql/Makefile and comment out the
+ change:
ifeq ($(PORTNAME), linux)
- LD_ADD += -ltermcap
- else
- to
+ LD_ADD+= -ltermcap
+ to:
ifeq ($(PORTNAME), linux)
- LD_ADD += -L/usr/lib/termcap -ltermcap
- else
+ LD_ADD+=
+
- 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.
1.9) Why do I get problems with ld.so?
This isn't really Linux specific, but is common on older Linux
installations. You must have a recent version of flex (2.5.2 or later)
- to compile Postgres95. Note that flex 2.5.3 has a bug: see

Question 3.4.

+1.11) How do I compile PostgreSQL on an a.out system?
First, you must install the dld library. This may be obtained
from Sunsite as:
Linux/libs/dld.3.2.7.tar.gz
- Second, comment out the LINUX_ELF line in src/mk/port/postgres.mk.linux
+ Second, add the following line to src/Makefile.custom:
+ LINUX_ELF=
+ (or use the customize script)
1.12) Why does make fail with:
- yacc -d /disk2/postgres95/src/backend/parser/gram.y
+ yacc -d /disk2/PostgreSQL/src/backend/parser/gram.y
make: /usr/bin/make: cannot execute binary file
+ 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.
src/Makefile.global?
This was a problem in 1.08 (they are Sun Solaris specific).
- It is fixed in 1.09.
+ It is fixed in 1.09 and 6.0
1.14) [DEBIAN] Where is libtermcap?
Debian Linux comes without the termcap library and uses ncurses
(which uses terminfo instead). There is no need to change the
- LIBCURSES variable in src/bin/psql/Makefile since Debian provides
+ CURSES_LIB variable in src/bin/psql/Makefile since Debian provides
a link from libncurses to libcurses (unlike SuSE-Linux --- see
Question 1.8).
- Edit src/bin/psql/Makefile and change:
-
+ You may need to edit src/bin/psql/Makefile and comment out the
+ change:
ifeq ($(PORTNAME), linux)
- LD_ADD += -ltermcap
- else
-
- to
-
+ LD_ADD+= -ltermcap
+ to:
ifeq ($(PORTNAME), linux)
- CFLAGS +=
- else
-
-
+ LD_ADD+=
----------------------------------------------------------------------
2.1) The linker fails to find libX11 when compiling pgtclsh
- Modify the src/Makefile.global to change
- X11_LIBDIR = /usr/lib
- to
+ Add the following to src/Makefile.custom
X11_LIBDIR = /usr/X11R6/lib
running scripts like createuser
This is a bug in V1.06-V1.07 of Postgres and is fixed in V1.08
+ and above.
3.2) I run postmaster and after that system says 'Bad system call(Core
dumped)'
- This indicates that you have no compiled shared memory support
+ This indicates that you have not compiled shared memory support
into your kernel. You need to recompile the Linux kernel to add this
feature.
3.3) When I try to start the Postmaster, why do I get an error of the form
Failed Assertion("!(file != 0):(null)", File:
- "/usr/local/postgres95/src/backend/storage/file/fd.c", Line: 257)
+ "/usr/local/PostgreSQL/src/backend/storage/file/fd.c", Line: 257)
!(file != 0) (0)
initdb: could not create template database
initdb: cleaning up.
You haven't build IPC support into your Linux kernel. You
will have to rebuild the kernel and switch on this option.
+3.6) Why does psql fail with:
+ psql: can't load library 'libpq.so.1'
-----------------------------------------------------------------------
-Section 4: Spurious Problems in Need of Verification

-4.1) Why doesn't the postmaster start the first time?
-
- Pawko Olszewski <alder@amg.com.pl> reported a problem that, using
- Linux kernel 2.0.18, the postmaster wouldn't start the first time
- it is run using
-
- postmaster -B 256
-
- but if run as
-
- postmaster -B 64
-
- killed and then restarted as
-
- postmaster -B 256
-
- everything was OK.
-
- I haven't been able to repeat this problem! Nobody else has
- reported anything similar.
-
+ Psql has been compiled to link dynamically with the libpq
+ library.
