So I installed Windows XP 64. off-topic, but Long sad story, but noneThe Intel compiler comes with both 32- and 64-bit versions, both Windows and linux. The 64-bit ones (ia64 and em64t, the latter being what you want) have 8-byte pointers. You can compile with either 32- or 64-bit compiler on either a 32- or 64-bit system. There is no automatic selection, it's up to you. Most alternatives have similar 32/64-bit capability.
of my PCI cards had drivers for Win64, so had to buy brand new video
card, USB 2.0 card. Plus my expensive HP printers and scanners are
no-go, as HP thinks a 2-yr old $699 printer and $3K scanner is too old
to support anymore ... grrrr.......! No problem, I moved them to my
Linux box.
Now the real hassle:: We have umpty-ump old FORTRAN programs that
would really benefitr from a 64 or at least 48-bit address space.
I try the latest Intel compiler, but the documetation is mighty cagey--
it says it's a 64-bit compiler, but "print *, sizeof( MyPointer )"
still reports "4", not "8". Am I missing some command-line option to
enable true 64-bit code generation?
If that's not possible,
Does anybody know of any REALLY, truly, fully 64-bit FORTRAN
compilers? One that generates true 64-bit code, with 8-byte pointers?
Preferably for Windows XP 64, but Linux could be harnessed in a pinch.
