| 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). |
