Re: ccplot 1.5-rc7 build error

[Peter K. <pet...@wa...>]

Ryan,

This indicates that python was indeed running in 64-bit mode, because
when forced to run in 32-bits it failed even earlier with basemap. The
hdfeos library itself is 64-bit, which is good. The only remaining
option is that the hdfeos.pyx module was compiled only as i386. Can you
please check, so that we are sure?

file /Library/Python/2.7/site-packages/ccplot/hdfeos.so

The build output you sent me last time seems suspicious regarding this
(the linker reports only -arch i386). If it is indeed to case, it will
be easier to contact someone upstream about this.
