As stated above, I don't think that this PR has much of a future. But if there is interest in introducing Meson to XBPS or if this could be discussed further, I'd be willing to continue working on it. This PR is production ready (except for missing tests and git revisions which both require modifying files). Fully static XBPS builds can be set up like this under Musl: |
-Werror is dropped, because Meson's werror is more strict than configure one. This implementation does not support running tests. The Kyua testsuite heavily relies on in-source builds. Tests would have to be rewritten (at least the Kyuafile files, but probably more) to support Meson. Meson does not support retrieving git info and providing it as a compiler flag. Meson's vcs_tag() mechanism supports outputting to a (header or source) file only. This would mean that xbps.h.in would have to be modified. No substitution is done on xbps.h.in. See void-linux#598 for explanation. _DEFAULT_SOURCE is dropped, because _GNU_SOURCE implies _DEFAULT_SOURCE. -D_FILE_OFFSET_BITS=64 is set automatically by Meson. Work in progress!

I do not expect this PR to be merged. As I understand it, XBPS is not under active development. Features & bugfixes are accepted when they are needed, active development of features is not the focus of XBPS. The current
configuresystem works, so I don't think this PR will be merged.I have discussed my intention of introducing Meson to XBPS in
#xbpssome time ago.I wanted to take a look at the internals of XBPS. I wanted to begin at the build system level to become familiar with XBPS's structure. This PR is a result of that. I also wanted to review the current build system. I have found #598 thanks to this. I have found additional issues while revisiting this now, but they are too inconsequential to make a PR for them.
I also find Meson more practical to work with both as an user and as a developer. Out of the box
compile_commands.jsonsupport,ccacheenabled by default, easy management of sanitizers etc. can be useful for development. Having an alternative build system can be an useful resource when debugging certain issues.Pros:
compile_commands.jsonsupportCons:
>=1.3.0(it shouldn't be that hard to support an earlier version though)
