Bug ID: 107313
Summary: Meson instructions on web site are non-optimal
Product: Mesa
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Other
Assignee: mesa-dev@lists.freedesktop.org
Reporter: jpakk...@gmail.com
QA Contact: mesa-dev@lists.freedesktop.org
The Meson page on the web site says, among other things, the following:
> if ninja decides to re-initialize meson, for example, if a meson.build file
> has been changed. Changing these variables will not cause all targets to be
> rebuilt, so running ninja clean is recommended
This is not good advice. We have spent a lot of effort in making sure that
rebuilds are reliable. If you change something and only a portion of your
sources are rebuilt, it means that the rest _did not need rebuilding_. The
reason for this is increased productivity so you don't need to rebuild files
unnecessarily.
Please remove the above segment from the web site or reword it to match
reality. If you have cases where our rebuild detection logic leaves something
unbuilt when it should have rebuilt it, please file bugs in Meson. We want to
get all those fixed.
