Package: libsuitesparse-dev
Version: 1:3.4.0-2
Dear libsuitesparse-dev maintainer,
The package is really useful for many scientific software.
However, The shared library files (*.so) are not available in Matlab.
For example, when I compile my mex file with the option
"-lcholmod /usr/lib/atlas-base/atlas/liblapack.a
/usr/lib/atlas-base/atlas/libblas.a",
Matlab crashes because
/usr/lib/libcholmod.so.1.7.1+00496421 cholmod_super_numeric+005621
tries to call
/usr/local/MATLAB/R2011b/bin/glnxa64/mkl.so+00973020 dpotrf+000076
When I used MUMPS library as "-ldmumps_seq", the situation was same.
However, when I directly assign the static libraries,
"/usr/lib/libdmumps_seq.a /usr/lib/libmumps_common_seq.a \
/usr/lib/libmpiseq_seq.a /usr/lib/libpord_seq.a",
it worked properly.
To link suitesparse, I guess I should list up the static libraries directly.
However, this link failed because the static libraries are not compiled
with the option '-fPIC'.
If possible, could you compile the static libraries with -fPIC ?

Compiling static libraries with -fPIC is strongly discouraged by the
Debian Policy. Quoting §10.2:
“As to the static libraries, the common case is not to have relocatable
code, since there is no benefit, unless in specific cases; therefore the
static version must not be compiled with the -fPIC flag. Any exception
to this rule should be discussed on the mailing list
[email protected], and the reasons for compiling with the
-fPIC flag must be recorded in the file README.Debian.”
I understand that you would like to have a special exception to this
rule in order to use the package in certain specific circumstances under
MATLAB. I don't think this special use case warrants an exception,
especially given the fact that MATLAB is not free software. As a
consequence, I am closing this issue. I would rather encourage you to
recompile SuiteSparse from source with the -fPIC flag.
Phillip: please note that your patch does not address the issue, because
libsuitesparseconfig is only a very tiny library which does not contain
the numerical routines; moreover I removed the _pic version in version
4.4.3-1 of the package that is currently waiting in the NEW queue.
Finally, note that I had not received your email because you had sent it
to [email protected] which does not CC the maintainer;
you should have also included [email protected]
(see /usr/share/doc/debian/bug-maint-info.txt.gz for details)
Cheers,
