Well, according to the buildd web page [1], the octave-ltfat package
built correctly on most of the official architectures in Debian unstable.
The unit testing failed on ppc64 (powerpc) [2] and s390x [3], and that
aborted the build process. The build on mips is takng a very long time
to finish and I suspect that it will also fail. At any rate, here are
the known reasons of failure:
* ppc64
=============== TEST_PFILT ==============
*** Error in `/usr/bin/octave-cli': munmap_chunk(): invalid pointer: 0x13871e18 ***
This is a memory management problem. This does not happen on other
architectures but I am not sure it is related to the s390x architecture
or it comes from the specific host used to build the package.
* s390x
=============== TEST_DGT ================
** On entry to ZGEMM parameter number 8 had an illegal value
This error is related to the call to the zgemm routine of the BLAS
library. Since the test passed on all other architectures, I would guess
that this is a compiler problem on s390x, but I really do not know.
In the previous releases of the Debian package octave-ltfat, we disabled
the unit testing for the problematic architectures, but this is not a
good option, because we ship then packages that are potentially buggy on
some architectures.
Any help on fixing these problems will be welcome.
Best,
Rafael
