Package: src:arpack Version: 3.7.0-1 Severity: serious Tags: ftbfs patch Dear maintainer:

I've put a bunch of build logs here: https://people.debian.org/~sanvila/build-logs/arpack/ The problem seems to be that the Makefiles wrongly assume that the system has at least 2 CPUs, which may or may not be the case. A simple solution that seems to work is to set 'LOG_FLAGS = -n 1' in both PARPACK/EXAMPLES/MPI/Makefile.am and PARPACK/TESTS/MPI/Makefile.am, but it would be even better to honor parallel=n setting in DEB_BUILD_OPTIONS when there is one, as in the patch below. I did not find a simple way to reproduce this in any system. The usual recipe is to try "taskset -c 0 dpkg-buildpackage" but this does not seem to work here, so if you need a test machine to reproduce the failure please contact me privately and I will gladly provide one.
