Passing in -fdefault-integer-8 is probably not going to work unless
you've done some major hacking; ipfint is typedefed in config.h, and
if it is a 4-byte type things will not be good for you.<br>
<br>
Have you used "otool -L" to make sure that the blas/lapack linking
is working the way you think it is? I would focus on getting it to
work with Netlib blas first, then veclib.<br>

<div>I'm inclined to think that I'm encountering a single problem
(when it manifests, the symptom is the same) and it is not
related to Matlab, since it occurs at the 'make test' stage of
the Ipopt build when using MUMPS, before even attempting to
build the Matlab interface. In this case, adding
' -fdefault-integer-8' to the FFLAGS passed to configure allows
it to compile and link just fine, but it results in the
following error when running make test:</div>

<div>Likewise for the C and Fortran tests. I'm not sure what this
means, but I get the same result with both the system
BLAS/LAPACK (-framework vecLib) or with the ones I can download
with get.Blas and get.Lapack in the ThirdParty directory.</div>
<div><br>
</div>
<div>So, I'm thinking that if I can get 'make test' to pass
consistently for a build with MUMPS, it will probably fix the
issue with the Matlab MEX file as well.</div>
