The new style build uses the well known configure script (via the autoconf procedure) a Makefile. You can recognize it because there will be a single $MIR/build directory within which we keep the usual bin, lib, etc... directories.
Although this method aims to be more portable (the old method often required editing compiler options in files that were hard to figure out for a newcomer), the drawback compared to the old-style is that you need to be in the MIRIAD home directory, and the chain of dependancies could mean a long (several minutes) build for what takes 0.5 sec in the old-style build. Example:
% edit $MIRPROG/calib/mfcal.for % cd $MIR % make install % cd -
Unlike the previous examples in the old-style build, this recipe should work for any style of change to the MIRIAD source code .
