Then on the Meson side we define
root = '/usr/i686-w64-mingw32/sys-root/mingw'
in the /usr/share/mingw/toolchain-mingw32.meson spec, while with
configure we invoke
configure \
--host=i686-w64-mingw32 \
--build=x86_64-redhat-linux-gnu \
--target=i686-w64-mingw32 \
--prefix=/usr/i686-w64-mingw32/sys-root/mingw \
--exec-prefix=/usr/i686-w64-mingw32/sys-root/mingw \
--bindir=/usr/i686-w64-mingw32/sys-root/mingw/bin \
--sbindir=/usr/i686-w64-mingw32/sys-root/mingw/sbin \
--sysconfdir=/usr/i686-w64-mingw32/sys-root/mingw/etc \
--datadir=/usr/i686-w64-mingw32/sys-root/mingw/share \
--includedir=/usr/i686-w64-mingw32/sys-root/mingw/include \
--libdir=/usr/i686-w64-mingw32/sys-root/mingw/lib \
--libexecdir=/usr/i686-w64-mingw32/sys-root/mingw/libexec \
--localstatedir=/usr/i686-w64-mingw32/sys-root/mingw/var \
--sharedstatedir=/usr/i686-w64-mingw32/sys-root/mingw/com \
--mandir=/usr/i686-w64-mingw32/sys-root/mingw/share/man \
--infodir=/usr/i686-w64-mingw32/sys-root/mingw/share/info \
is there any difference between the notion of the 'sysroot' vs
the install 'prefix' ?
The pkg-config files for mingw also typically define
prefix=/usr/i686-w64-mingw32/sys-root/mingw
With regards,
Daniel
