It's this: https://www.gnu.org/software/make/manual/html_node/File-Function.html I think it was added in GNU make 4.0 around 2013. > this does not work if different TARGETs are installed to the same OUTPUT > > or is the plugin independent from target? > then maybe a copy would be better than a symlink I believe the plugin is target independent but will change between gcc versions. The plugin is only ~100k so a file copy should be fine. I can submit a new patch tomorrow when I'm back on the dev box. Patrick
From: Patrick Oppenlander <patrick.oppenlander@gmail.com> The ar, nm and ranlib tools will automatically load plugins from the lib/bfd-plugins directory if present. With this symlink in place it is no longer necessary to use the gcc- prefixed versions of these tools (or the --plugin argument) to handle LTO objects. --- litecross/Makefile | 2 ++ 1 file changed, 2 insertions(+)
