FP tests fail on non-x86 architectures on Fedora 22 (AArch64, PPC64LE) #2844
Comments

@HRM: Hi there! Sorry for the late reply… I'm the package-owner in Fedora… Did you have a look at the spec-file I use, yet? There are lot's of exceptions for failed tests for e.g. %ix86 and %arm, just because of this problem, currently… I'll add the failing test to the excludes for aarch64 to the spec-file and ping pbrobinson to have him rebuild it. Possibly a rhbz# would be good to track this one… Cheers |

I had that feeling that I forgot something... Bug reported: https://bugzilla.redhat.com/show_bug.cgi?id=1222401 |

Besser82: the solution is not to skip failed tests. The solution should be fixing of those tests to make them work. I hope to make a build on Power8 machine (where FPU follows IEEE754-2008) to check what kind of results it will give. AArch64 uses IEEE754 as well. x86 should use it too but it is x86 - architecture with such pile of mess that anything can happen there. |
|
Should be fixed in packaging now. See RHBZ #1222401. |

changed the title

Besser82: this bug was not about Fedora packaging but about code. Please reopen. |

Similar failures on PPC64LE: The following tests FAILED: Build with disabled R support. |

@hrw hi! any ideas how i could quickly debug it? shall i use qemu or do you have maybe better suggestion? |
|
qemu is one way. Getting access to AArch64 or Power machine is other - but I do not know any publically accessible ways now. |
|
https://www.linaro.cloud/ is one way. But I do not know how long you would wait. |
|
@hrw i had once access to linaro, but it took a long time to get access :) so qemu it is :P |
|
@hrw ok so finally i've managed to put together a qemu env for this ! \o/ so yeah i can confirm this.... it puzzles me a bit why those specific errors, but looking into it :) |
|
@hrw btw what are the cmake/compiler flags you are using to compile shogun for aarch64 as i've just seen that |
|
http://arm.koji.fedoraproject.org/koji/buildinfo?buildID=362126 has build logs. |

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions. |
|
@vigsterkr nowadays you can use Travis CI to have tests built on !x86. |

Hi
Shogun 4.0.0 is part of Fedora 22 packages collection. We do build for AArch64 architecture. Compiles fine, pass most of tests but some fail:

Build is available online at http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=2991856 where you can check whole build log and also check which packages were installed to build it (in root.log).
From what I see the problem is with floating point operations as results differ at last two digits from time to time.
