2 | ODE - Mac CFM Carbon Port | ||
3 | (contact Frank Condello <pox@planetquake.com> with questions regarding this port) | ||
4 | |||
5 | Although ODE contains a MacOSX makefile, and some individuals have implemented ODE in | ||
6 | Cocoa, I opted to use (and prefer) CodeWarrior. This also opens up ODE to MacOS8 & 9 | ||
7 | users, without scarfing functionality in MacOSX (same binaries run on both platforms). | ||
8 | |||
9 | The 'ode_CW7.mcp' project contains release and debug targets to create static ODE and | ||
10 | DrawStuff libraries. | ||
11 | |||
12 | 'examples_CW7.mcp' contains targets for the entire ODE test suite, plus a couple other | ||
13 | test programs which were posted to the ODE mailing list. | ||
14 | |||
15 | |||
16 | ----------------------------- | ||
17 | Compiling Notes: | ||
18 | |||
19 | You'll need to extract the CodeWarrior projects from the 'CW7_projects.sit.bin' archive | ||
20 | (They're nearly a meg uncompressed so this was done to be bandwith friendly on the CVS). | ||
21 | |||
22 | Projects require CodeWarrior 7 or above (recreating them with earlier versions shouldn't | ||
23 | be too difficult). The projects use relative paths and are meant to be compiled from | ||
24 | 'contrib/Mac_CFMCarbon/'. Don't move them! | ||
25 | |||
26 | All the libraries build into the 'lib/' directory, all test applications build into | ||
27 | 'contrib/Mac_CFMCarbon/mac_testbin/' (and must be run from that directory since the | ||
28 | texture path is hard-coded). | ||
29 | |||
30 | You'll need to compile the release ODE library, and the DrawStuff library before | ||
31 | compiling the examples. | ||
32 | |||
33 | The ODE 'configurator' has not been ported, but a Mac-friendly 'config.h' header has been | ||
34 | manually hacked together (all PPC Macs should be fine with this header). Single or double | ||
35 | precision can be defined in the 'CommonPrefix.h' header found in | ||
36 | 'contrib/Mac_CFMCarbon/mac_source/'. | ||
37 | |||
38 | 'contrib/Mac_CFMCarbon/mac_source/' also contains any mac specific additions to the main source. | ||
39 | The directory structure here matches the main source tree, and I would recommend that this | ||
40 | format is maintained when making additions, since the access paths are touchy (more below...) | ||
41 | |||
42 | Some issues were encountered with duplicate header names. CodeWarrior tends to be | ||
43 | unforgiving about this sort of thing but fudging with the access paths eventually | ||
44 | cleared up the problem. If ODE fails to compile, make sure the <ode/objects.h> and | ||
45 | "objects.h" or <timer.h> and <Timer.h> are actually pointing to the correct header. | ||
46 | |||
47 | You'll need Apple's OpenGL SDK (with GLUT) in your compiler path to build DrawStuff. I've | ||
48 | added redirection headers in 'contrib/Mac_CFMCarbon/mac_source/include/GL/' to properly | ||
49 | link with the Apple headers (since the projects are set to follow DOS paths). | ||
50 | |||
51 | The examples link against a crapload of static libraries, but my initial builds using | ||
52 | ODE, MSL, GLUT, and DrawStuff shared/merged DLL's proved unstable (mostly problems with | ||
53 | SIOUX spawning multiple sessions, and crashes in Classic). Static libs just worked better | ||
54 | in the end, but the test apps are a little bloated as a result, and need to be re-linked | ||
55 | whenever a change to a library is made. | ||
56 | |||
57 | IMPORTANT: You must use the same 'CommonPrefix.h' settings for libraries, and test apps | ||
58 | (i.e. double or single precision). | ||
59 | |||
60 | |||
61 | ----------------------------- | ||
62 | Running the test apps: | ||
63 | |||
64 | The test apps will show the SIOUX CLI prompt when run. Just hit OK to ignore it, or add any | ||
65 | DrawStuff arguments. You'll want to log output to a file for 'test_ode'. | ||
66 | |||
67 | There are two extra test programs in the 'mac_source' directory. Both were posted to the ODE | ||
68 | mailing list by OSX users. 'test_stability1' visualizes some internal issues with ODE, and | ||
69 | 'test_stacktest' is a standalone GLUT program (doesn't use DrawStuff) that can be useful | ||
70 | to stress test the library, and give you an idea of just how much stack memory you're | ||
71 | going to need for large systems. | ||
72 | |||
73 | ISSUES: | ||
74 | |||
75 | The carbon DrawStuff lib uses GLUT to make life easy, but GLUT isn't exactly bug-free | ||
76 | or stable on the Mac... Try moving the mouse around if a simulation is running slowly | ||
77 | on OS9 (it's not ODE's fault, but rather a poor carbon GLUT implementation - seems GLUT stalls | ||
78 | when it's not getting system events - I haven't seen this problem on OSX). | ||
79 | |||
80 | The 3D view may not update if typing in the SIOUX console window. | ||
81 | |||
82 | You cannot pass startup args to GLUT due to the way the DrawStuff library initializes. | ||
83 | |||
84 | 'Write Frames' doesn't actually do anything at the moment. | ||
85 | |||
86 | The 'test_joints' app seems broken (though I don't know what the intended effect should be) | ||
87 | |||
88 | |||
89 | ----------------------------- | ||
90 | TODO: | ||
91 | |||
92 | - Re-add shared library targets (if stability issues are resolved). | ||
93 | - Implement 'Write Frames' in DrawStuff. | ||
94 | - Write a Carbon compatible configurator | ||
95 | - Create CodeWarrior 8 projects (once I scrounge up enough dough for the update). \ No newline at end of file | ||
