Hi John,
I'll take a look at trac #2965. You should be able to build the
7.0.1-rc2 tarball
simply by unpacking it and following the instructions in the README.
(In short,
configure, make then make install ought to work.)
If it doesn't build properly out of the box, I'd be interested in
hearing about it.
AFAIK, only 6.10.4 has been tested as bootstrap compiler for 7.0.1-rc2,
although
I expect 6.12.3 should work too. There is always the possibility of
some hiccup,
however.
Best Wishes,
Greg

Hi Greg,
Thanks very much for all your work on this, and Barney Stratford too.
This is great news. I'm doing a lot of numerical work with Doubles
at the moment, so progress is quite welcome!
I can try building 7.0.1-RC using a 32-bit 6.12.3, although probably
not until the weekend. I'll let you know how it goes.
If there are any special build instructions for this, maybe you could
update trac #2965 with details?
Cheers,
John

Hi,
I built ghc 7.0.1-rc2 yesterday 64-bit on Snow Leopard. Much of
the work
in getting ghc to build 64-bit was done by Barney Stratford; the
MacPorts
ghc 6.10.4 has built successfully in 64 bit mode for a number of
months.
Until just a few weeks ago 6.12.x and HEAD wouldn't build 64-bit
because
of changes in ghci. These changes were in part to remove the
limitation
that modules
loaded by ghci had to be located below the 2 GB address boundary.
Unfortunately,
they revealed code paths in ghc's Mach-O linker that were never
tested. (See
bug #4318. Other bugs may be partial duplicates; the tickets
probably need
to be examined to check which ones are distinct.)
The good news is that the linker patches were done just in time
for 7.0.1.
You should be all set to try the release candidates on Snow
Leopard 64-bit.
I built my 7.0.1-rc2 using a 64 bit 6.10.4. My original 64-bit 6.10.4
was bootstrapped
using a 32-bit 6.10.4 compiled on Leopard. Reports of trouble
building the
7.0.1 release candidates using a 32-bit bootstrap compiler would be
especially
useful.
Best Wishes,
Greg
