• [igraph/igraph] Test suite error on mips64el architecture (#1469)

    From Andreas Tille@21:1/5 to All on Mon Nov 16 16:50:02 2020
    Hi Debian Mips team,

    the package igraph fails on mips64el autobuilder[1] with

    ...
    228: Eigenvector centrality (igraph_eigenvector_centrality): FAILED (arpack.at:59)
    ...

    ERROR: 264 tests were run,
    1 failed unexpectedly.
    2 tests were skipped.
    ## -------------------------- ##
    ## testsuite.log was created. ##
    ## -------------------------- ##

    Please send `tests/testsuite.log' and all information you think might help:

    To: <igraph@igraph.org>
    Subject: [igraph 0.8.3] testsuite: 228 failed

    You may investigate any problem if you feel able to do so, in which
    case the test suite provides a good starting point. Its output may
    be found below `tests/testsuite.dir'.

    I tried to track down the issue on eller.debian.org to create the said tests/testsuite.dir since upstream needs this to investigate.
    Unfortunately I was not able to reproduce the issue there but got:

    ...
    228: Eigenvector centrality (igraph_eigenvector_centrality): ok
    ...

    ## ------------- ##
    ## Test results. ##
    ## ------------- ##

    263 tests were successful.
    3 tests were skipped.
    make[3]: Leaving directory '/home/tille/igraph-0.8.3+ds/tests'

    Any idea why the package builds on eller but not on the autobuilders?

    Kind regards, Andreas.
