Can ifort build for 64-bit linux on Itanium platform from x86_64?

[rookie2010]

We got Intel Fortran Compiler 11.1 on our x86_64 linux box. Now we need to
compile out code for 64-bit linux on HP Itanium platform. My understanding
is that Itanium architecture is different from x86_64. My 32-bit ifort (10.0.025)
on Windows supports IA-32, Intel 64 and IA-64 environments. Can Intel Fortran Compiler
11.1 on our x86_64 support 64-bit Itanium?

Please find machine and ifort info below and your opinion is very much appreciated.

You would need to have the cross-compiler installed, and use it instead of the native compilers. (added later: TimP points out below that there was no cross-compiler in this version of Intel Fortran).

The output of ls would have shown an ia64 subdirectory if you had installed the cross-compiler at the same time as the ia32 and intel64 versions.

$ ls
ia32 iccvars.csh iccvars.sh ifortvars.csh ifortvars.sh intel64

does not show an ia64 subdirectory, as it should if you had the IA64 cross-compiler installed.

To do cross-compilation, you would issue the command

$ source ifortvars.sh ia64

instead of

$ source ifortvars.sh intel64

Are you sure you want to do cross-compilation and put up with the inconveniences that go with it?

[TimP]

ifort 11.1 for linux comes in 3 architecture versions: ia32, intel64, and ia64 (Itanium). All of them are native compilers which share a license; you would require an Itanium system to build for Itanium target with the Intel compilers.

Tim is correct - on Linux, the only "cross-compile" available is to build IA-32 on x64. On Windows, 11.1 provides an IA-32-Itanium cross-compiler.
