UMFPACK is a set of routines of for solving sparse linear systems using the Unsymmetric MultiFrontal method. I suggest that it be included under dev-libs.

Created attachment 59253 [details] Updated ebuild for UMFPACK v4.4 I have updated the ebuild to UMFPACK v4.4. Significant changes include: - Updated header. - Automated determination of source filename and url (see the N and V variables near the top of the ebuild - Is this a good idea or not?). - Changed dependency on dev-libs/atlas to sci-libs/atlas. - Minor change to sed trickery in src_compile() (Is there a better way to achieve this?) - Install header files to /usr/include/umfpack rather than /usr/include (See comments by JWE at http://www.octave.org/octave-lists/archive/octave-maintainers.2005/msg00219.html) The ebuild works cleanly on my x86 system. Nathanial, can you test?
worked with me
Works fine here as well, and I think it should be included into regular portage since it's a requirement for the great "colorize" Gimp plugin: http://registry.gimp.org/plugin?id=5479 (see also http://www.cs.huji.ac.il/~yweiss/Colorization/ )

I slighlty updated the ebuild and tested in the scientific gentoo overlay (http://gentooscience.org).
(In reply to comment #7) > I slighlty updated the ebuild and tested in the scientific gentoo overlay > (http://gentooscience.org). Thank you. I built it with gcc-4.1 on an amd64 system, to use with the svn version of scipy. I get the following error when I try to build scipy (for what its worth): /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/libumfpack.a(umfpack_di_col_to_triplet.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC /usr/lib/libumfpack.a: could not read symbols: Bad value collect2: ld returned 1 exit status /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/libumfpack.a(umfpack_di_col_to_triplet.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC /usr/lib/libumfpack.a: could not read symbols: Bad value collect2: ld returned 1 exit status error: Command "x86_64-pc-linux-gnu-gcc -pthread -shared build/temp.linux-x86_64-2.4/build/src/Lib/linsolve/umfpack/_umfpack_wrap.o -L/usr/lib -Lbuild/temp.linux-x86_64-2.4 -lumfpack -lamd -llapack -lblas -lcblas -latlas -o build/lib.linux-x86_64-2.4/scipy/linsolve/umfpack/__umfpack.so" failed with exit status 1

It looks like the ebuild would benefit to build a libtoolization, as lapack did.
Hi I updated the umfpack ebuild on the gentooscience overlay: - version bump to 4.6 - added cblas flag - added libtoolization allowing shared and static libraries building. Please test and report here. Sebastien

Looks good here (gcc-4.1, ~amd64). I was also able to build scipy with umfpack support, using your improved ebuild. Thank you!
umfpack-5.0.3 in cvs. Thanks all for testing.
