Subject: [PATCH] meson: Stop detecting -Wl,--version-script=
|
|
MIME-Version: 1.0

With its version 16.0, the LLVM's linker turned on
|
|
--no-undefined-version by default [1]. This breaks how we detect
|
|
--version-script= detection, because at the compile time there's
|
|
no library built yet that we can use to make --version-script=
|
|
happy. Unfortunately, meson does not provide a way to detect this
|
|
either [2].
|
|
|
|
But there's not much sense in detecting the argument either. We
|
|
already special case some systems (windows, darwin) and do the
|
|
check for others, which are expected to support versioned
|
|
symbols, because of ELF. Worst case scenario - the error is
|
|
reported during compile time rather than configure time.
