RE: 64 bit gcc

[Grove, David]

Thank you for your comment.

I downloaded the binary development snapshot of the 64 bit enabled egcs from
www.sunfreeware.com.

I can successfully create 64 bit object modules.  (as verified by the 'file'
utility).

But when attempting to link with 64 bit libraries supplied by Informix (they
used Sun Workshop 5.0 compiler with -xarch=v9) it fails with the following
message:

"gcc: language arch=v9 not recognized"

I used "-mcpu=ultrasparc" and "-m64" in the command string, but didn't help.

My question is, does the use of -xarch=v9 by Informix in their original
compile of libraries using Sun cc preclude me from using gcc to compile new
64 bit objects and link to the Informix libraries?  In other words, are
there any options I can set in the command string of gcc so that I can link
with libraries compiled with Sun cc using "-xarch=v9"?  If not with the
3/06/2000 snapshot of egcs, perhaps the current development snapshot, or the
anticipated gcc 3.0?

The motivation, of course, is to avoid having to buy Sun's compiler.  It's
ironic that Sun recommended (in a training class I attended) the GNU
compiler over their own product!

Thank you for your comments.

This is not fully supported in GCC 2.95.2, the latest official release
of GCC.  It is supposed to work in development snapshots that will
eventually become GCC 3.0

IIRC, this is a flag for the linker, so you have to use -Wl,-xarch=v9
so that GCC doesn't attempt to understand the flag itself, and passes
it literally to the linker.  I'd think -m64 might implicitly pass this
flag to the linker, but I can't see any hooks to do it in the GCC
configuration files.  Try to use just -m64 -v and see whether the flag
shows up in the linker command line.  If not, pass it in explicitly
as suggested above.

Wow!  Cool :-)

64 bit gcc

[Grove, David]

Sir/Madam:

I'm looking to produce 64 bit executables.

Running Solaris 8 on Sun E3000. (Ultrasparc, Sun4u).

Have tried using the version of gcc Sun includes as a courtesy with the
Solaris distribution media.  I used -mcpu=ultrasparc and -m64, but didn't
work.

Is there a way to compile to 64 bit executables with gcc?

Thank you for your time.

GCC 2.95.2, the latest official release of GCC, doesn't fully support
64-bit sparc.  I believe recent development snapshots of GCC do.

Likewise.

Of course Red Hat GNU Pro comes with source code, it just isn't for
free.  If you purchase it, you get the sources and the right to
re-distribute them, just like mandated by the GNU GPL, that regulates
the distribution of GCC, binutils, GDB and all derived products, such
as Red Hat GNU Pro.

64 bit gcc

[Bibhas Kumar Samanta]

Hi,

  Is Solalis 64 bit version of gcc/gnu available.
 If yes pls advice be which release to use.

 What 'bout HP-UX 11.0 PA2.0w architecture gcc/gnu release , heard about cygnus's

 Gnupro, but that seems not with source-code.


 Any help would be appreciated.

 Thanks,
 Bibhas
