BenV's notes

Just ran into this one, noting it down for anyone else with this error:

Trying to compile Lua 5.2.3 (which should try to invest some in autoconf / cmake or something) gave me this lovely error:

Reason: it needs to link against ncursus in Slackware (or alternatively libtermcap, but ncursus worked for me).
Solution – use make MYLIBS=”-lncursus”:

make MYLIBS="-lncurses"
cd src && make linux
