Hi, I am not exactly if this is the correct place to ask this
question or not - my apologies if misplaced.
I just installed octave 2.9.9 using darwinports 1.3.2 and tried to
run a small matrix test case for matlab (mytrit.m from Johan
Helsing of Lund University). When I try to run it, it gets to the
line:
R=chol(-A);
and I get the error message:
error: Missing CHOLMOD. Sparse cholesky factorization disabled
[If I comment out that section, everything else seems to run fine.]
Now as near as I can tell cholmod should be part of SuiteSparse
(which was also installed [v. 2.4.0_0] as part of this process).
The headers for cholmod are found in "/opt/local/include/
ufsparse". Unless there was some error in the installation that
was not reported, I should have CHLMOD I think. There is also a
chol.oct found in "/opt/local/libexec/octave/2.9.9/oct/powerpc-
apple-darwin8.8.0/chol.oct".
Unfortunately, the I did not try to build it verbose - and cannot
find any log or error files that might point out what actually
happened. Does anyone have any ideas on what I possibly did wrong
and how I might fix it?
I have a copy of 2.1.73 which was installed from binaries provided
by hpc.sourcefourge.net last year in /usr/local/bin - but /opt/
local/bin comes first in my path. I had originally tried to
install the 2.9.9 binaries from there, but it complained because I
did not have UMFPACK (probably because I did not have ufsparse at
that time).
Thank you for your time.

P.S. running Mac OS-X 10.4.8 on a G4.
I'm not sure if this is the behavior of the octave port, but the
behavior of a MacPorts port *should* be that if you just install the
port, you just get the basic software. If the software can optionally
use some other feature (like suitesparse or cholmod in this case),
then there should be a variant of the original port (octave) that you
can use to enable this functionality (such as +suitesparse or
+cholmod -- note this is just hypothetical; the octave port has no
such variant). The maintainer of the octave port should comment on
how it actually functions.
