When I wanted to upgrade octave it failed compiling and I checked the build.log for errors. I found several points that came to my attention. The configure script doesn't find the tputs function from sys-libs/ncurses package, although the ncurses package gets pulled in by the @system set and therefore is mandatory. From the build.log: checking for library containing tputs... no configure: WARNING: I couldn't find -ltermcap, -lterminfo, -lncurses, -lcurses, or -ltermlib! The manpage for tputs says to include curses.h and term.h in that order to get the definitions for the terminfo low-level routines. waebbl@artus ~/code $ equery belongs /usr/include/curses.h /usr/include/term.h * Searching for /usr/include/curses.h,/usr/include/term.h ... sys-libs/ncurses-5.9-r5 (/usr/include/curses.h) sys-libs/ncurses-5.9-r5 (/usr/include/term.h) Both of these files belong to the ncurses package. In the summary section of the configuration the logfile also says, it won't include TERM support: TERM libraries: I don't know whether this can be ignored or not, because the configure script finds (n)curses.h include files as well as termcap.h include file, but it doesn't test for the term.h include file.
