The current release of Freeserf (20161008) won’t build using Linux/Debian. The reason for this are some C++-issues.
It seem’s that CLang/VC will have no problems but gcc. See the
src/objects.h. The command
= delete won’t work/build with gcc (Debian 4.9.2-10)
See https://github.com/wittnet/freeserf for a quick’n dirty workaround so you can build it again.
