This repo provides some dependencies needed by libactpol and thus by moby2. sla_refro-moby2-1: a C-wrapped version of a single routine from the open-sourced Fortran version of slalib. Provides library slarefro for libactpol. slim_v2_7_1-moby2-1: a patched version of libslim. This fixes some bugs in the handling of 8-bit integers. sofa_20180130: The stated version of libsofa (astrometric coordinate conversions), but with our own Makefile added to compile the right kind of shared library. For sla_refro and sofa, it's enough to export PREFIX=$MOBY2_PREFIX make make install But for libslim you'll need to configure like this: ./configure --prefix=$MOBY2_PREFIX --with-zzip make make install
