Hi Peter,

I got the output from the cc verbose (-#).
Looks like there is a "-hread" towards the end.

Thanks.

Apparently, your compiler does not understand the -pthread option. I've
read on the net that the Sun compiler options for thread-safety have
changed a few times, but I haven't found a system yet. If you just want
to get going, edit src/template/solaris and replace -pthread by the right
option (-mt in your case?).

Hi Peter,

You are right. I looked at the man page and it does not
have the -pthread option but the -mt option.

Perhaps there is a way to automate and detect which
one it has ?

I find in the man page that there is another option
-###, which is like -# but does not actually execute:

The following options are interpreted by cc:

-# Show each component as it is invoked (verbose mode).

-### Show each component as it is invoked, but, unlike the
-# option, do not actually execute.

Maybe a better way is to do cc -flags and it will return
all the flags and then grep for pthread and see if it is a valid
option. Here is the output of cc -flags:

TIP 6: Have you searched our list archives?

http://archives.postgresql.org

I think we need some code in templates/solaris to identify the compiler
and use -pthread for gcc and -mt for Sun's compiler.

Would you please try the attached patch and let us know how it works.
If it works, we can include it in 7.4.1.
