Ticket #35508 (closed defect: fixed)
arpack port does not work on Lion with GFortran 4.6.2 due to Accelerate problem
|Reported by:||gcrosswhite@…||Owned by:||mmoll@…|
I have seen problem this before and thought it had been squashed in this port but it has appeared again.
ARPACK has a problem in that it uses the BLAS routine ZDOTC which has a different calling convention in Accelerate.framework then that used by GFortran which causes crashes that I have encountered in my code. I know that this was the source of the problem because when I downloaded arpack-ng and patched it manually, replacing
X = ZDOTC(....)
then the problems went away.
I am not sure how people would prefer to see this problem solved, but I could submit a patch making the changes above if you all would like.
