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 *
|
|
388
|
31 * When building make sure your HOME path is unix style - i.e. without
|
|
|
32 * a drive letter.
|
|
259
|
33 *
|
|
388
|
34 * once you have done this, configure and make.
|
|
251
|
35 *
|
|
259
|
36 * windows '95 - I haven't tested this under '95, it will probably
|
|
|
37 * build but I konw there are some limitations with cygwin under 95 so
|
|
|
38 * YMMV. I build with NT4 SP3.
