fsi and 64 bit
f#

Hi,
I am "seeing" that FSI.exe is a 32 bit .NET app.
Even when I run it on a 64 bit vista machine.

I was able to "get over it" by using:
corflags /32bit- /force fsi.exe
sn -Vr fsi.exe

and fsi.exe "started" running 64 bit all of a sudden.
Should F# work om 64 bits?
Is there a good reason for why fsi was compiled this way?

Would it be possible to actually get fsi compiled as a non cpu-specific executable in the future?

.

Hi,
I would love it if someone from the MS F# team, perhaps lurking in these forums could address this issue regarding the default state of fsi.exe out of the box.

I'm interested in knowing:

  • Why FSI is a 32-bit only app as opposed to an "Any-CPU" app.
  • Are there any plans to change that (provide two executables/any-cpu executable)
  • What the "right way" to compile F# from the source code

Have you seen
[link:blogs.msdn.com] ?
It seems this is a known issue, at least. Not much help to you, but may bring some comfort...

Thanks for the linkage!
They indeed point to the same type of workaround I used out of habit.

It's interesting to know that amongst the other "issues" that the 64 Jitter has in x64 (like inlining function receiving structs which is OK in x86 since .NET 3.5 SP1) tail calls are yet another such issue...

Hopefully they get it right by CLR 4.0

Actually, the sources of the compiler are available, meaning that, in theory, you should be able to compile it with whatever flags you like.
In practice, I have not heard of anyone building F# from sources, but if someone gives it a try and succeeds, I would be interested to know how to reproduce the steps.

I can confirm that was definitely possible, at least before the CTP.

To be more accurate, I seldom used the official pre-compiled versions. The source code and Makefile were provided in each version, and the compilation process was usually straightforward.

However, since CTP, they moved to a MS-specific building tool which I have no knowledge of (nor do I have the energy or intention to learn for the moment), so I can not speak for the CTP and beyond.
