Hi Bastien,

As I suggested on the other thread, I downloaded and tried MIRA 3rc4d:
http://www.chevreux.org/tmp/mira-3rc4d.tar.bz2

$ ./configure  --with-boost=/Users/myusername
and:
$ ./configure --enable-64  --with-boost=/Users/myusername
...
We are building on ............................... Darwin
CPU supports 64 bit? ......... ................... no
Compiler ......................................... gcc

i.e. As before, MIRA is not recognising my Mac OS 10.5 Leopard machine
as 64bit. Again, running make seems to give me a working 32bit MIRA.

Is there anything in the logs I should look for?

If I hack the configure script to include the -m64 flag as used on SunOS
(as I described earlier), then configure does attempt to do a 64bit build.
As before, this fails with the boost skim issue.

I will look into this next.

Thanks

Peter
