21 /* Building under cygwin
23 * The approach I have taken with this port is to use primarily the UNIX
24 * code base adding stuff that is MS-Windows specific. This works quite
25 * well, and is in keeping with my perception of the cygwin philosophy.
26 * Note that if you make changes to this file you do NOT want to define
27 * WINDOWSNT, I repeat - do not define this, it will break everything
28 * horribly. What does get defined is HAVE_MS_WINDOWS, but this is
29 * done by configure and only applies to the window system.
31 * The important thing about building is that it is done on a binary
32 * mounted filesystem. i.e. something mounted like: mount -b c:
33 * /binary. If you do not do this then compilation of el files may
34 * produce garbage. As of b24 there are fixes in xemacs to make
35 * building on text mounts but I don't generally do this. Make sure
36 * you have installed cygwin32 b18 + patched dll (which can be found
37 * at http://www.lexa.ru/sos or on my home page
38 * http://www.parallax.co.uk/~andyp. Alternatively when b19 comes out
39 * the patched dll will be unnecessary. Also make sure your HOME path
40 * is unix style - i.e. without a drive letter.
42 * Note that some people have reported problems with the patched
43 * cygwin.dll on Sergey's home page so you may want to use the one on
44 * mine which I *know* works.
46 * once you have done this, configure and make. If you want unexec
47 * support you need to download a.out.h from my web page or use cygwin
48 * b19. You probably want to build with mule support since this
49 * addresses crlf issues in a sensible way.
51 * windows '95 - I haven't tested this under '95, it will probably
52 * build but I konw there are some limitations with cygwin under 95 so
53 * YMMV. I build with NT4 SP3.
57 * the fileio stuff merely uses the unix system calls this means that
58 * the mount type of your fs will determine how files are edited. This
59 * is fine except in the instance that you want to convert one to the
60 * other. In this instance I would like to bring the buffer_file_type
61 * code into the picture without all the other windows-nt
62 * cruft. Apparently the best way to do this is use the mule coding
65 * process support needs fixing although basic support works (a la
