Re: custom arpack linked with custom ATLAS and lapack not found by octave 3.2.0

[Tatsuro MATSUOKA]

Hello

Source of ARPACK is designed for f77 complier.

in UTIL/second.f
24:       EXTERNAL           ETIME

ETIME in gfortran is internal function.
This line should be commented out like
24:*       EXTERNAL           ETIME

I hope the above is helpful for you.

Regards

Tatsuro
