Re: 64-bit UMFPACK?

[David Bateman]

UMPACK functions have two letters to define the types of the arguments. 
The first letter is either "z" or "d" defining whether the functions are 
double complex or double. The second is either "i" or "l" defining if 
the indexing arguments are int or long... The configuration script of 
octave selects either "int" or "long" type for otave_idx_type, and the 
same type will be used by the UMFPACK functions, and so there should be 
nothing to do for 64-bit UMFPACK...

However, I do know that the COLAMD stuff including colamd and symamd is 
not 64-bit safe, and similarly for the load/save code, these are things 
that still have to be fixed... For the COLAMD stuff, the original author 
Tim Davis is working on a replacement of COLAMD that wil address this 
issue and will release it soon So I propose to do nothing there till 
this new code is released...
