There is never any reason to not do this since this script is supposed
to be run by developers and testers who are concerned with the details
of the problems.
It also helps with intermittent or hard-to-reproduce errors.
We have no test coverage for regeneration at all, which is why issues
like #1246 slide by without us noticing. With this, we will run a regen
on every test during `ninja test` after it has been compiled. This will
not affect test times too much since the regen will not rebuild anything
at all since there have been no source changes.
Set the rules for the symlinking on the target itself, and then reuse
that information while generating aliases during the build, and then
pass it to the install script too.
At installation, if the executable is a ELF file, we try to fix the
dependencies in the binary section.
If a executable has been compiled with the --static flag, there is
no .dynamic section in the ELF binary and so we need to handle this case.
We were storing the pkg-config path on the class as a static variable --
PkgConfigDependency.pkgbin. When we regenerate via Ninja, the found-deps
are all cached in a pickled coredata, so if you have a statement that
does dep.get_pkgconfig_variable(), it will raise the following exception
because the static class variables are per-meson-invocation.
To fix this, we store the pkg-config binary as both a class variable and
an instance variable.
