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 is recommended. If you are

5) 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 two files
produced by configure:
(1) In src/Makefile.global, change the line
SNPRINTF =
to read
SNPRINTF = snprintf.o
(2) In src/backend/port/Makefile, add "snprintf.o" to OBJS. (Skip this
step if you see "$(SNPRINTF)" already listed in OBJS.)
Then build as usual.
