How could I change boost release variant to use cxxflags=-O2?

On my machine cxxflags for variant=release is -O3 by default.
I need to change it to -O2. Please advise how to proceed.

I am fine with defining a new variant as well, if someone could advise me on that.

Solution

  • Just use:

    <variant>release:<cxxflags>-O2

    as requirements on top-level project. Options specified with cxxflags are passed to gcc after all the other options, so -O3 will be overridden.
