arpack compile failure

[michael.g.ross.98@…]

I can't upgrade arpack on 32-bit Snow Leopard. Build log is attached.

It seems that the directory /opt/local/lib/gcc43/i386 doesn't exist. Can you double check and make sure? I don't have gcc43 installed, but the corresponding directory for gcc44 *does* exist.

[michael.g.ross.98@…]

That is correct, it does not exist, though x86_64 does, oddly enough.

[jmroot (Joshua Root)]

Are you sure you're on a 32-bit machine? Check sysctl hw.cpu64bit_capable. If not, see #22116.

[michael.g.ross.98@…]

Yes, it is 32-bit (first gen MBP):

hw.cpu64bit_capable: 0

[jmroot (Joshua Root)]

I seem to recall that gcc calls itself (actually more accurately) i686 rather than i386. Is there an /opt/local/lib/gcc43/i686 directory?

[michael.g.ross.98@…]

No, x86_64 is the only architectural subdirectory, and it seems otherwise configured as i386:

Solved by revision 68674. Thanks mmoll!
