1) What tools do I need to build and install PostgreSQL on Solaris?
|
|
|
|
|
|
|
|
|
|
You will need
|
|
|
|
|
|
|
|
|
|
- GNU zip (for installing the documentation)
|
|
|
|
|
- GNU make
|
|
|
|
|
- GNU readline library (optional)
|
|
|
|
|
- GCC (if you don't have Sun's compiler)
|
|
|
|
|
|
|
|
|
|
If you like Solaris packages, you can find these tools here:
|
|
|
|
|
http://www.sunfreeware.com
|
|
|
|
|
|
|
|
|
|
If you prefer sources, look here:
|
|
|
|
|
http://www.gnu.org/order/ftp.html
|
|
|
|
|
|
|
|
|
|
You can build with either GCC or Sun's compiler suite. We have heard
|
|
|
|
|
reports of problems when using gcc 2.95.1; gcc 2.95.3 or later is
|
|
|
|
|
recommended. If you are using Sun's compiler, be careful *not* to
|
|
|
|
|
select /usr/ucb/cc; use /opt/SUNWspro/bin/cc.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
2) Why do I get problems when building with OpenSSL support?
|
|
|
|
|
|
|
|
|
|
When you build PostgreSQL with OpenSSL support you might get
|
|
|
|
|
compilation errors in the following files:
|
|
|
|
|
|
|
|
|
|
src/backend/libpq/crypt.c
|
|
|
|
|
src/backend/libpq/password.c
|
|
|
|
|
src/interfaces/libpq/fe-auth.c
|
|
|
|
|
src/interfaces/libpq/fe-connect.c
|
|
|
|
|
|
|
|
|
|
This is because of a namespace conflict between the standard
|
|
|
|
|
/usr/include/crypt.h header and the header files provided by OpenSSL.
|
|
|
|
|
|
|
|
|
|
Upgrading your OpenSSL installation to version 0.9.6a fixes this
|
|
|
|
|
problem.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
3) Why does configure complain about a failed test program?
|
|
|
|
|
|
|
|
|
|
This is probably a case of the run-time linker being unable to find
|
|
|
|
|
libz or some other non-standard library, such as libssl. To point it
|
|
|
|
|
to the right location, set the LD_LIBRARY_PATH environment variable,
|
|
|
|
|
e.g.,
|
|
|
|
|
|
|
|
|
|
LD_LIBRARY_PATH=/usr/local/lib:/usr/local/ssl/lib
|
|
|
|
|
export LD_LIBRARY_PATH
|
|
|
|
|
|
|
|
|
|
and restart configure. You will also have to keep this setting
|
|
|
|
|
whenever you run any of the installed PostgreSQL programs.
|
|
|
|
|
|
|
|
|
|
Alternatively, set the environment variable LD_RUN_PATH. See the
|
|
|
|
|
ld(1) man page for more information.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
4) Why does my 64-bit build sometimes crash?
|
|
|
|
|
|
|
|
|
|
On Solaris 7 and older, the 64-bit version of libc has a buggy vsnprintf
|
|
|
|
|
routine, which leads to erratic core dumps in PostgreSQL. The simplest known
|
|
|
|
|
workaround is to force PostgreSQL to use its own version of vsnprintf rather
|
|
|
|
|
than the library copy. To do this, after you run 'configure' edit a file
|
|
|
|
|
produced by configure:
|
|
|
|
|
|
|
|
|
|
In src/Makefile.global, change the line
|
|
|
|
|
LIBOBJS =
|
|
|
|
|
to read
|
|
|
|
|
LIBOBJS = snprintf.o
|
|
|
|
|
|
|
|
|
|
(There might be other files already listed in this variable. Order
|
|
|
|
|
does not matter.)
|
|
|
|
|
|
|
|
|
|
Then build as usual.
