You will need
GNU zip (for installing the documentation)
GNU make
GNU readline library (optional)
Sun Studio CC or GCC

You can build with either GCC or Sun's compiler suite. For better code

gcc 2.95.3 or later is recommended. If you are using Sun's compiler, be

This is probably a case of the run-time linker being unable to find some
library. On solaris 8 and older it should be 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.,

5) How can I compile for optimal performance?
On SPARC architecture Sun Studio is strongly recommended for
compilation. Try using -xO5 optimalization flag to generate
significantly faster binaries. Do not use any flags which modify
behavior of floating point operations and errno processing (e.g.
-fast). These flags should raise some nonstandard PostgreSQL behavior
for example in the date/time computing.

If you do not reason to use 64-bit binaries on SPARC, prefer 32-bit
version. The 64-bit operations are slower and 64-bit binaries are slower
then 32-bits. And on other side a 32-bit code on the AMD64 CPU family is
not native and that is why 32-bit code is significant slower on this
CPU family.

6) How to compile PostgreSQL with Sun Studio?
6) Where I can download prepared Solaris packages?
On Solaris 10 you can performed following steps:
export CC=/opt/SUNWspro/bin/cc
export CFLAGS=-xO5
export LDFLAGS=-lm
./configure --without-readline
gmake
The PostgreSQL is bundled with Solaris 10 (from update 2). Official
packages are also available on
<http://pgfoundry.org/projects/solarispackages/>. Packages for older
Solaris version (8, 9) you can be obtained from
<http://www.sunfreeware.com/> or <http://www.blastwave.org/>.
7) Where I can download prepared Solaris packages?
The PostgreSQL is bundled with Solaris 10 (from update 2). Official
packages are too available on

The PostgreSQL 8.2 has implemented dtrace support. You can enable it by
the --enable-dtrace configure switch. If you want to compile a 64-bit
code with dtrace you must specify DTRACEFLAGS='-64', e.g.
