Subject: RE: make check: src/DLD-FUNCTIONS/ .............................. ** On entry to DLASCL parameter number 4 had an illegal value

I'm using the mkl libraries that come with intel compiler 11.1... I also have MKL 10.2 installed but I am not using those.   I had to use -ff2c to get the compile to work, probably due to whatever gcc problems you were mentioning.

I have set up ARPACK as follows:
                home = /path/to/ARPACK
                DIRS         = $(UTILdir) $(SRCdir)
                ARPACKLIB  = $(home)/libarpack.a
                LAPACKLIB = $MKLPATH/libmkl_lapack.a
                BLASLIB = $MKLPATH/libmkl_ia32.a
                FFLAGS  = -O0
                MAKE    = /usr/bin/make

I guess the problem was that I hadn't converted to a shared lib.  I did so using
ar -x mylib.a
gcc -shared *.o -o
And now the test passes! is now failing, so I'm off to figre that one out...
  src/DLD-FUNCTIONS/ ................................panic: Segmentation fault -- stopping myself...

How can I determine why these are failing? Is there a logfile somewhere?  Thanks!
