[Pkg-octave-devel] Debian packages for Octave 2.9.10 available in experimental

[Rafael Laboissiere]

The Debian packages for Octave 2.9.10 are released to the experimental
distribution [1].  They have not been uploaded to unstable because octave2.9
build-depends on libglpk-dev >= 4.15, which is still waiting for approval in
the NEW queue.  The new GLPK packages can be accessed through my personal
apt-getable repository [2].

I have to apply two patches to the package, one regarding GLPK (already
submitted to bug at octave.org [3]) and another related to the test in
syscalls.cc (attached below).  I do not know why I had to increase the sleep
period from 0.1 to 1, but "make check" was hanging in an unpredictable way
(is perhaps my machine too slow?)

Otherwise, the compilation went smooth and only two tests did not pass.
Attached below is a file with excerpts of fntests.log containing the error
messages. One problem regards randp and the other happens for the
element-by-element sparse matrix division.  I hope the problems are not
serious but I would appreciate if someone could comment on them.
