If for some reason you prefer not to build from packages (for +example, because the machine is offline), then you can convert this step into +the \"final\" installation and skip the rest. For this your will need to +change the \c{configure} command line above along these lines: + +\ +> build2\build2\b-boot configure ^ + config.cxx=g++ ^ + config.cc.coptions=-O3 ^ + config.bin.lib=shared ^ + config.install.root=C:\build2 +\ + +| + +\li|\n4. Install\n + +Next, we use the staged toolchain to build and install the \"final\" toolchain +from the package repository using the \c{bpkg} package manager.
