Hi; we've just merged Paolo's patchset that converts the build system to use Meson. This should mostly be fairly seamless for the average developer (we hope) but there are a few things to be aware of:* you probably want to do a distclean or otherwise do a clean build when you first update your git tree to a version of master with Meson (especially if you do in-tree builds) * out-of-tree builds should continue to work basically normally * we have retained compatibility for an "in-tree build" workflow where you run configure/make in the source tree, but this is now implemented by having configure create a build tree for you under-the-hood (but do consider switching to just doing out-of-tree builds)
If you do an in-tree build, do the 'make distclean' _before_ a 'git pull' of the new code. If you don't clean first, the pull attempt is likely to complain about various trace.h files, so that is a good reminder. And if you manage to pull anyway, you may need to rewind your tree back to v5.1.0 before attempting the in-tree 'make distclean', then re-try the pull.
