[lsb-discuss] x86_64 binary RPMs for both AMD and Intel 64-bit distos?

We have decided to ship LSB binary RPM packages for a new commercial
Following instructions on the LSB web site, we've had good success in
building ia32 and x86_64 architecture binaries that work across redhat,
suse, debian/ubuntu, etc.
Apparently, most Intel 64 bit chips also support "EMT64T", which is
nearly the same as x86_64 (amd64), or at least compatible as far as gcc
Is it possible to ship only x86_64 LSB RPMs -- say compiled on x86_64
Debian -- so that these would run on *most* 64-bit (AMD or Intel) Linux
LSB distros ???
- Its not critical that we have 100% coverage, since we will also
distribute a source RPM that the outliers can use.
- The application is not particularly performance critical, so we
probably don't care about tiny optimization differences in the binaries,
so long as the code runs correctly.
? If it is possible to ship x86_64 binaries for both, are special GCC
options required when building? Are there (LSB) RPM spec / packaging
? If it is not possible, is it feasible to GCC cross-compile on x86_64
to target IA64 using lsbc++ ?
Thanks for any advice,
