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.
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) How do I ensure that pg_dump and pg_restore can handle files > 2 Gb?

By default, gcc will build programs that only handle 32-bit file offsets.
This is not a real problem for the server but can easily be trouble for
pg_dump and pg_restore.  Before running 'configure', set your CFLAGS variable
to specify support for files with 64-bit offsets.  This has been verified
to work on Solaris 7:

     CFLAGS="`getconf LFS_CFLAGS`"; export CFLAGS
