But you must build and 34acquire tools. Not all of the tools distributed with EMX work properly, and 35some additional ones are required. 36 37First, the configure script distributed with ncurses will not run as-is in EMX. 38You can generate a new one if you have autoconf built for EMX. You will need 39the EMX development tools, of course. Get these programs to start: 40 41 GNU m4 program (version 1.4) 42 GNU autoconf (version 2.13). 43 GNU patch (version 2.5) 44 45Apply the autoconf patches from 46 47 https://invisible-island.net/autoconf 48 ftp://ftp.invisible-island.net/autoconf 49 50These are ordered by date: 51 52 autoconf-2.13-20030927.patch.gz 53 autoconf-2.13-20030927-emx.patch.gz 54 55I built my development environment for ncurses using EMX 0.9c at the end of 561997. Much of the EMX patch for autoconf was done originally by J.J.G.Ripoll, 57using a similar environment (he prefers using the 'ash' shell). Newer versions 58may fix these problems: 59 60 + The pdksh program distributed at Hobbes and Leo (with a 1996 date) is 61 defective. It does not process "here documents" correctly (which 62 renders it useless for running the autoconf script). I built my own 63 copy of pdksh 5.2.13, which does have the bug corrected (documented 64 in the change log for pdksh). 65 66 + I also built from sources (because the distributed binaries did not 67 work) the cmp, diff programs. 68 69 Other required utilities such as ar, cat, chmod, cp, gawk, grep, mv, 70 ls, rm, mkdir, sed, sort and tr worked. 71 72Once you have autoconf patched and installed, run 'autoconf' from the top-level 73directory of ncurses to generate the EMX-specific configure script. 74
