#35508: arpack port does not work on Lion with GFortran 4.6.2 due to Accelerate problem -----------------------------------+---------------------------------------- Reporter: gcrosswhite@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.1.2 Keywords: | Port: -----------------------------------+---------------------------------------- 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(....) with call ZDOTC(X,...) 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. -- Ticket URL: <https://trac.macports.org/ticket/35508> MacPorts <http://www.macports.org/> Ports system for Mac OS
