Re: ARPACK library causing problem while compiling Octave-2.9.10

[Daniel Oberhoff]

Hi,

When I was preparing a 2.9.10 port for macports I ran into similar  
problems with arpack. The problem there was that the arpack port used  
different compiler directives/compilers for compiling the fortran  
files. The difference is in the way underscores are used. I have no  
overview which is used when, but I have seen __fun and _fun before,  
fun_ seems unusual to me.

The compiler directives should be the same for all of your fortran  
libraries (arpack, blas, maybe also suitesparse?). And in your case  
they seem not to be.

You could try to find out where those functions are usually defined  
(maybe lapack or blas) and then look at how the names are mangled  
inside that library (ldd on linux, otool on osx) and then compare to  
how they are mangled in arpack.

It is a little weird in your case also though, because the undefined  
references seem to be inside arpack, so I wonder how you ever got  
arpack compiled. Or was it a binary install using rpms or debian  
packages? In that case the corresponding dependency manager is broken.

Octave is usually happey when all fortran libs mangle names the same,  
detects the mangling and applies it everywhere, it just has to be  
consistent.
