I need to compile my code for Itanium, but it seems that all of the compilers (ecc, gcc, orc) require an Itanium machine to do so. Any suggestions?

How are you going to test the executable? – mmmmmm Jan 26 '13 at 13:56

9Er, gcc can be a cross-compiler, what's the problem? – Marc Glisse Jan 26 '13 at 13:56

@Mark, I am, but on a simulator: IATO – Parsa Jan 26 '13 at 13:57

Can't the simulator run the compiler ? However the cross compilation is probably better – mmmmmm Jan 26 '13 at 13:58

No it can't, I need to compile it on my own. – Parsa Jan 26 '13 at 14:00

You need to set gcc up as a cross compiler. This involves building binutils and gcc yourself.
The IA64wiki at http://www.gelato.unsw.edu.au/IA64wiki/CrossCompilation has a tutorial on how to set this up.

4There used to be a script collection called `crosstool` that would take care of all the downloading and building of the myriad utilities and libraries for cross compilation... – Kerrek SB Jan 26 '13 at 14:14

I can only tell how I did it, perhaps not the best way or best tools.
I developed a very small priority-based Itanium kernel and test tasks long time ago. I started to develop it again (demand paging, fork system call...). The last time I compiled it is a week ago.
What I found is that compiling a cross compiler is a very hard task nowadays for IA64. And to get gcc and binutils to work together is an other problem. I tried many times compile cross compiler and binutils - no success). It seems that Itanium support has been forgotten, at least very much worse than some years again.
However, I found packages for the cross compiler, binutils and ski simulator binary. All starts working immediately (well, ski does not show TLB info).
I have Ubuntu 12, Linux kernel 3.2 AMD64
How to find the tools:
- Ski:
- Ubuntu Sotfware Center: Ski/IA-64 instruction set simulator (binary)
- Cross tools (work together!):
- gcc-ia64-linux-gnu-4.7.1-0.1.20120606.fc18.1.x86_64.rpm
- binutils-ia64-linux-gnu-2.22.52.0.3-3.fc18.x86_64.rpm

(Hmm... I compiled the Kernel, I think that application library support can be bad or non existent?)

there is lots of application support, see the debian ia64 port: https://www.debian.org/ports/ia64/ – Janus Troelsen Aug 05 '15 at 12:02

There's Itanium version of Windows, so of course Visual studio can generate code for Itanium

I didn't mention any version. Neither did the OP. That means at least one version of MSVC supported Itanium – phuclv Jun 28 '15 at 13:50

Visual Studio 2010 is the last version to support Itanium according to http://www.infoq.com/news/2010/04/Itanium-Dropped – Janus Troelsen Aug 05 '15 at 11:59
