I built OpenSCAD on Ubuntu 16.04 and ran the default set of tests using "ctest" with no arguments. There are 3 failures: The following tests FAILED: 469 - opencsgtest_issue1165 (Failed) 471 - opencsgtest_issue1215 (Failed) 781 - throwntogethertest_issue1215 (Failed) Is this expected behaviour or should I open an issue?

Hi Doug, Issues with OpenGL drivers tend to influence tests. Is this on a VM or on actual hardware? I believe both these are related to rendering of z fighting being non-deterministic across platforms. I _think_ all tests pass on Ubuntu 14.04. We have to disable a bunch of them under Ubuntu 12.04 VMs (e.g. Travis). See https://github.com/openscad/openscad/blob/master/scripts/travis-ci.sh We may have to disable *_issue1215 as well. Please make note of this in an issue, perhaps make a generate Ubuntu 16.04 issue? -Marius > On Apr 29, 2016, at 20:43 PM, doug moen <doug@moens.org> wrote: > > I built OpenSCAD on Ubuntu 16.04 and ran the default set of tests using "ctest" with no arguments. > There are 3 failures: > > The following tests FAILED: > 469 - opencsgtest_issue1165 (Failed) > 471 - opencsgtest_issue1215 (Failed) > 781 - throwntogethertest_issue1215 (Failed) > > Is this expected behaviour or should I open an issue? > _______________________________________________ > OpenSCAD mailing list > Discuss@lists.openscad.org > http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org

@Marius: I can't prove it's a driver issue. I'm not using a VM. I'm using an NVidia graphics card, GT 218 [GeForce 210], GL_RENDERER is "Gallium 0.4 on NVA8". I'm using the default Nouveau open source driver. If I switch to the NVidia-340 proprietary driver, the same tests fail. Force Goldfeather does *not* fix the problem: the same tests fail with both of the above drivers. So I've tested 4 variations with no change in behaviour. I will file an issue.
