gcc - Using -flto with autotools -

-

given c++ program uses gnu autotools, what's easiest way compile -flto (link time optimization)? understanding is customary on unix such optimization flags specified user or packager, not programmer.

according this post, -flto flag needs passed compilation flag , linker flag, so:

./configure cxxflags="-flto" ldflags="-flto" ...

or possibly:

./configure cxxflags="-flto" ldflags="-wc,-flto" ...

might work.
