patch -Np1 -i ../ncurses-&ncurses-version;-patch: This patch fixes a compile problem with GCC-3.2 because Ncurses uses constructions that are not valid in ANSI C++ and don't compile with recent GCC versions that conform to the standard. --with-shared: This enables the build of the shared ncurses library files. chmod 755 *.5.2: Shared libraries should be executable. Ncurses's install routine doesn't set the permissions properly so we do it manually instead. ln -sf libncurses.a libcurses.a: Some programs try to link using -lcurses instead of -lncurses. This symlink ensures that such programs will link without errors.
