Hi,<div><br class="webkit-block-placeholder"></div><div>We've supported x86-64 since 2002 or so. There are already handcoded x86-64 kernels in the correspodning x86_64_sse directory.</div><div><br class="webkit-block-placeholder"></div><div>This is just a matter of your system not being recognized correctly as x86-64, but ia32 for some reason. First make sure that you are really setting -m64 in CFLAGS prior to running configure, and if that doesn't work you could try to update the config.sub and config.guess from ftp.gnu.org.</div><div><br class="webkit-block-placeholder"></div><div>In any case - when you run configure one of the very first lines should echo the system type. That should be x86-64 and not ia32 when your compiler flags are set correctly.</div><div><br class="webkit-block-placeholder"></div><div>Cheers,</div><div><br class="webkit-block-placeholder"></div><div>Erik</div><div><br><div><div>On Aug 21, 2007, at 8:43 PM, Mithun Sridharan wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"> <font size="-1">Dear Sirs,<br> <br> I'm Mithun Sridharan and am employed at Sun Microsystems in Germany. <br> I am working on porting Gromacs to Solaris x64 platforms and am currently facing issues in compiling the sources.<br> The compilation works well for 32 bit with GCC as well as Sun Studio 12 processors.<br> <br> However, on compiling with -m64 (for a 64-bit space), the compilation fails for the file nb_kernel330_ia32_sse.s.<br> This file contains the assembler intrinsics and I would like to create a similar fole for AMD Opteron based processors as well as for SPARC.<br> I would like to know how these assembler files were generated.
