Dear fellow Linux developers,

it gives me a tremendous joy to be the first one to post to this forum and to announce
that the compiler team at Sun Microsystems is pleased to make available alpha builds of
Sun Studio Compilers for the Linux OS.
I remember the time when I first proposed this
idea back at Yggdrasil times and here I am some odd number of years later seeing
the Alpha bits appear on the Sun Download Pages for you to experience. It took
a number of years and an incredible team of engineers to build this product for
Solaris OS and now, we are bringing this 15 years of compiler experience to the Linux OS.

This time, however, we want to add a little twist to how we continue the development
of the product that has already set a number of performance records -- we want you,
the developers, the guys who crunch CPU fearlessly with edit-make-compile cycles
to tell us what you want.

It is our top most priority to hear what you have to say -- experiment with the bits,
participate in forums and let us know what you think. As you can see
this is just a second build of a continuous program and some functionality
is still missing (most notably a C++ compiler) or isn't fully implemented yet.
Despite these limitations we think that what's available is interesting
enough to make it worth downloading the bits.

And finally, I'm actually writing this while at a LinuxWolrd 2005 Expo and Conference in
San Francisco, USA (and there's a guys breathing down my shoulder who wants me
to release this very terminal at once, cause he has to check his email) so I would really
love to see all of you folks drop by Sun microsystems/Sun Studio booth and have
a chat with us. You'll get a chance to talk to the folks who never attend trade shows
because they have enough of the ISO C and C++ official meetings as it is. Quite a nice
opportunity to ask questions like, what where they thinking making C++ sensitive to
where you put parenthesis in your expression. That sort of questions.

Oh yeah, and one more thing:

if you want to get the latest scoop on Sun Stduio Compilers for the Linux OS go right here:

or if you want to chat with us in person -- go the the Linux World 2005:

and register using this promotion code: N0388.

Thanks and have fun,
Compiler team @ Sun microsystems.

 

 

Are there plans to make C++ compiler available?

 

 

Absolutely! In fact, we think we can make it available as early
as mid September. The biggest hurdle for us is g++ ABI
compatibility, which may take a bit longer to overcome. Of
course, since the very nature of the Technology Preview
program is to make early bits available early -- we will
make C++ compiler available even if it is a little bit rough
around the edges.

All in all -- check back with us in a couple of weeks and don't
forget to give us your honest feedback. I mean, may be the
g++ ABI compatibility is not that big of a deal, after all. But
we wouldn't know unless you tell us ;-)

Thanks,
Roman.

 

 

Hi,

I am quite enthusiastic about running Sun Studio Compilers on Linux. We are operating quite a few UltraSPARC- and Opteron-based boxes in our center at Aachen, Germany.
The perspective of offering the same development envrionment on Solaris and Linux is really beautiful.
After some twiddling I was able to compile C and Fortran toy programs, using sunstudio, the debugger and even TotalView on my laptop. This was really a great experience!

And now - except for the C++ compiler - Sun MPI (as part of Sun HPC ClusterTools) is the remaing piece which is missing to complete the development suite for an Opteron cluster from Sun.

My experiences so far:

1)
This is how it works on a Pentium M laptop running SuSE 9.1
uname -a
Linux mobilc2 2.6.5-7.95-default #1 Thu Jul 1 15:23:45 UTC 2004

LD_LIBRARY_PATH=/opt/sun/sunstudio10u1/prod/lib f95 \
-xdebugformat=dwarf -g -lgcc_s program.f
sunstudio -D a.out # to start the sunstudio debugger
totalview a.out # to start the TV debugger

2)
Trying
f90 end.f

on an Opteron running
Fedora Core release 3
Linux linuxoc01.rz.RWTH-Aachen.DE 2.6.11-1.27_FC3smp #1 SMP Tue May 17 20:38:05 EDT 2005


3)
as well as on another Opteron running
SuSE Linux 9.2 (x86-64)
Linux linuxpc20.rz.RWTH-Aachen.DE 2.6.8-24.11-smp #1 SMP Fri Jan 14 13:01:26 UTC 2005

I get nice error messages like some others have reported:

* glibc detected * double free or corruption (!prev): 0x092c0c98 *

The program cannot be tinier and just consists of the Fortran "end" statement.

I am looking forware to using Sun Studio a lot in the future.

best regards
Dieter
