I'm exploring building with guile 2.2 because guile-gnutls built with guile 3.0 is only available in experimental, and even there, missing for arm64. FAIL: tests/swh.scm - lookup-origin And then hangs indefinitely. I've seen it run for hours at a time. Works fine with guile 3.0. In tests/swh.log, there is not much there, though obviously seems problematic: warning: cannot run Web server for tests: Address already in use In thread: In procedure listen: Wrong type argument in position 1 (expecting open file port): #f I don't have any debian patches applied to tests/swh.scm and do not think any other patches are likely to affect this here, but you never know. :) live well, vagrant
