21 /* Building under cygwin
|
|
|
22 *
|
|
|
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.
|
|
|
30 *
|
|
|
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 will
|
|
|
34 * produce garbage. Make sure you have installed cygwin32 b18 +
|
|
|
35 * patched dll (which can be found at http://www.lexa.ru/sos or on my
|
|
|
36 * home page. Alternatively when b19 comes out the patched dll will be
|
|
|
37 * unnecessary. Also make sure your HOME path is unix style -
|
|
|
38 * i.e. without a drive letter.
|
|
|
39 *
|
|
|
40 * once you have done this, configure and make. The
|
|
|
41 * undump phase will fail but that is to be expected. To run you need
|
|
|
42 * to set EMACSLOADPATH, EMACSDOC, EMACSDATA etc appropriately and then do:
|
|
|
43 * temacs -batch -l loadup.el run-temacs
|
|
|
44 *
|
|
|
45 * What I want to do
|
|
|
46 *
|
|
|
47 * the fileio stuff merely uses the unix system calls this means that
|
|
|
48 * the mount type of your fs will determine how files are edited. This
|
|
|
49 * is fine except in the instance that you want to convert one to the
|
|
|
50 * other. In this instance I would like to bring the buffer_file_type
|
|
|
51 * code into the picture without all the other windows-nt cruft.
|
|
|
52 *
|
|
|
53 * Also the undumped version should be able to do path guessing, I
|
|
|
54 * don't know why it doesn't currently.
|
|
|
55 *
|
|
|
56 * Ideally a dumped version would be done but I'm not sure I am up to
|
|
|
57 * the task.
