Dear fellow Macporters :)
I was wondering if it were possible to have, at the same time, two install
directories for MacPorts; e.g. /opt/local and something else.
Why? Because as a maintainer, I am almost obliged to compile most of the ports with the universal
variant; however, space on my 128 GiB SSD is rather scarce, and don’t use the 32-bit binaries
anyway: compiling universal leads to a waste of resources. So the idea would be to have two
separate directories, a "working" one, on the SSD (/opt/local) with only 64-bit binaries,
possibly optimized (-march=native as in my previous post), and a "development" copy,
somewhere on an external disk, with universal binaries, that I’d use, well, for development. Both
would be fed out of the SVN tree.
Possible or quixotist?
Yes, definitely. We've had 3 different copies of MacPorts installed at
the same time.
I always set --prefix=$PREFIX --with-tclpackage=$PREFIX/lib/tcl/macports
to ensure that each copy installs all its files into its own prefix.
