Hello,
I'm trying to compile postgresql and I got this message telling me
to inform you:

"../../../../src/include/storage/s_lock.h", line 806: #error: PostgreSQL
does not have native spinlock support on this platform. To continue the
compilation, rerun configure using --disable-spinlocks. However,
performance will be poor. Please report this to pgsql-bugs@postgresql.org.

This is the configure line i used:
MAKE=gmake CC=/opt/SUNWspro/bin/cc CFLAGS="-xtarget=opteron
-xarch=amd64" CXX=/opt/SUNWspro/bin/CC CXXFLAGS="-xtarget=opteron
-xarch=amd64" LDFLAGS="-xtarget=opteron -xarch=amd64" ./configure
--without-readline

If i try this configuration command instead:
MAKE=gmake CC=/opt/SUNWspro/bin/cc CFLAGS="-fast"
CXX=/opt/SUNWspro/bin/CC CXXFLAGS="-fast" LDFLAGS="-fast" ./configure
--without-readline

It compiles but then i get a 32 bit executable which is not what i want.

This is on a solaris 10 with amd processor using the sun forte 11 compilers.

Are there any fix for this?

Thanks.

choose an index scan if your joining column's datatypes do not
match

You'd need to do something about adapting src/backend/port/tas/solaris_i386.s
to amd64, and then change the part of s_lock.h that mentions Solaris/386
to also accept x86_64 not just __i386. Also see src/template/solaris
which controls configure's determination of which tas file is needed.

It's possible that the assembly code would work as-is on amd, in which
case you'd just need a one-liner change in s_lock.h and maybe some
adjustment of the template file.

Please send a patch if you fix this.

regards, tom lane

It doesn't compile with the options to create amd code.
cc -Xa -xtarget=opteron -xarch=amd64 -c solaris_i386.s

The same file compiles without those options:

Unfortunately i won't be able to help unless you have some code for me
to try out.
