[ODE] Compiling ode with Opcode

[Ed Jones]

Howdy,

I managed to get ODE+Opcode to work with Dev-C++ (i.e. mingw), here are 
some of the things I did that you might like to try.
I may well miss some steps out, in which case let me know and I'll dig 
about a bit more in the source to see if I can find anything else that I 
changed;

In the ODE user-settings file you need to set this, which I'm guessing 
you've already done;
PLATFORM=mingw

In the Opcode/Makefile, on the "gcc -c -o ..." line change the -O3 to 
-O0 (that's "minus oh zero") I dunno why you need to do disable the 
compiler optimisations like this, there's been some discussions about it 
on this list I think, my trimesh collisions didn't work correctly 
without it.

In IceFPU.h, at the top, just after the line "#define __ICEFPU_H__" put;
  #ifdef WIN32
  #undef WIN32
  #endif
Which just switches off the inline assembler stuff. Okay it's probably 
gonna be slower, and there should probably be a way of converting the 
inline assembler to work with mingw but I don't know what that would be, 
and my hacky method seems to work anyway.

Do "make all" from the Opcode directory
Do "make all" in the ODE directory

Hope that make sense.
Cheers,
Ed.
