11 Ok, so this little text file is pretty short right now. These things
|
|
|
12 take time to think of.. :-)

19 The example files that come with MikMod default to 30k stack buffers
|
|
|
20 (option stack=30000 on the wlink command line). This is a safety pre-
|
|
|
21 caution and by no means a requirement.
|
|
|
22
|
|
|
23 You can usually safely use a 10k stack if you are using an interrupt
|
|
|
24 driven MikMod_Update() and you can safely use a 5k stack if you are
|
|
|
25 using polling (calling MikMod_Update() from a main program loop).
|
|
|
26
|
|
|
27 ----------
|
|
|
28
|
|
|
29 If you are writing a module player and are NOT calling MikMod_Update()
|
|
|
30 from an interrupt, then you can safely remove /ZU from the following
|
|
|
31 modules in the /MikMod directory:
|
|
|
32
|
|
|
33 MDRIVER.C
|
|
|
34 VIRTCH.C
|
|
|
35
|
|
|
36 Removing /ZU will slightly reduce code size and increase replay speed.
|
|

|
40 If you are using the IDE and want to add PMODE/W to the list of valid
|
|
|
41 targets, follow these steps:
|
|
|
42
|
|
|
43 a) copy PMWBIND.EXE and PMODEW.LNK to your watcom/binw diectory.
|
|
|
44
|
|
|
45 b) Load WSYSTEM.LNK, and inster the contents of PMODEW.LINK into it
|
|
|
46 at the very top.
|
|
|
47
|
|
|
48 c) Load IDEDOS32.CFG. Insert a line that reads:
|
|
|
49 Target *.exe, dw2e_, "PMODE/W Executable"
|
|
|
50
|
|
|
51 d) Load IDE.CFG. Around line 840, you will find the following line:
|
|
|
52 VSwitch 0, dr2??, "System:", SYS, " ", ONE, REQ, dos4g
|
|
|
53 Inser this line below it:
|
|
|
54 VSwitch 0, dw2??, "System:", SYS, " ", ONE, REQ, pmodew
|
|
|
55
|
|
|
56 e) This is the tricky part. There are several lines in IDE.CFG that
|
|
|
57 contain 'dr2'. Each of these [excluding the special case in step
|
|
|
58 d] must be duplicated, and 'dr2' replaced with 'dw2' (no other
|
|
|
59 changes required). Do this right and you will have full IDE cap-
|
|
|
60 ability with the pmode/w extender!
|
|
|
61
|
|
|
62 There you go, all set to compile with pmode/w within the Watcom IDE!
