meson build: simplify build script, increase usability #71
Conversation
|
Still a WIP, submitted for early feedback. I believe that meson should handle the dependencies for the cross use case, but have not yet tested. Somewhere in there I found that Qt6 was being pulled in for This should build on native Linux (enable Qt or disable ruledit for now), further testing to come. Summary output should look something like this, which I hope will make determining build configuration a lot more straightforward than parsing the string given to meson: A bit of churn, unfortunately, as I've also run a code formatter over the build files. Please let me know if you're interested in this work (or parts of it) and I can work on that, though the deps summary is really enabled (at least without much boilerplate) by having deps be a dependency or 'not found'. |
This will produce a summary of the build environment,
enabled features, and identified dependencies (with version where
possible).
To enable this work, many dependencies have been rewritten to directly
use the `foo_dep = dependency('foo', required: false)` syntax, enabling
us to take advantage of the 'not found' behaviour for many current
conditionals (see features below), significantly reducing boilerplate
requred. Meson cross build files should still enable resolution of
libraries in the cross build environment.
Targets of opportunity (combo with 'try', 'true', 'false', deps with
conditional logic) have been converted to the meson `feature` option
type, which has several advantages (including helpers) and reduces boilerplate.
Features that are `disabled` are treated as 'not found' for the purposes
of dependency resolution.

Looks promising.
Sometime in the past we went the other direction; dependency() -> compiler.find_xxx() for supporting crosser based builds via cross properties. That's not to say that the situation is necessary still the same (it's quite likely that we now could construct working cross file some other way) |
Agree, I can split some things (e.g. meson |
