I'm trying to package 2.0.10 for Void Linux but hitting this test failure. Info on how to fix/disable the test would be much appreciated! :)

[arvidn]

my guess is that there's some issue related to using "overlayfs".

[MIvanchev]

@arvidn How can I disable it?

[arvidn]

from my reading, it seems you may be running a "LiveCD" installation, with the underlying operating system mounted as read-only, and then an overlayfs with a writeable partition.

[MIvanchev]

I am more than willing to disable the test instead of investing time to fix it... is there a command line switch or something?

[arvidn]

I believe the CMakeList.txt uses glob to pick up the tests, so just removing the file would do it. When building with boost-build, you can remove the line in tests/Jamfile mentioning test_copy_file.cpp.

[arvidn]

I think this PR would fix it. would you mind testing it on your build image?
