|
|
Hello.
I checked out the current svn (r19) and tried to compile the code on linux using bud. The first problem i ran into was in derelict/sdl/syswm.d.
I got the following error:
Code: | derelict/sdl/syswm.d:73: struct derelict.sdl.syswm.SDL_SysWMinfo conflicts with derelict.sdl.syswm.SDL_SysWMinfo at derelict/sdl/syswm.d:67
|
I changed:
Code: | version(linux)
{
struct SDL_SysWMmsg;
struct SDL_SysWMinfo;
}
version(Unix)
{
struct SDL_SysWMmsg;
struct SDL_SysWMinfo;
}
|
to:
Code: | version(linux)
{
struct SDL_SysWMmsg;
struct SDL_SysWMinfo;
}
// version(Unix)
// {
// struct SDL_SysWMmsg;
// struct SDL_SysWMinfo;
// }
|
This did the trick.
For the second problem i do not have a solution.
Code: | /tmp/ccUO20f8.s: Assembler messages:
/tmp/ccUO20f8.s:1015: Error: symbol `_D4yage6system6device6Device10getSupportFiZb1si' is already defined
/tmp/ccUO20f8.s:1021: Error: symbol `_D4yage6system6device6Device10getSupportFiZb1si' is already defined
|
Greping through the whole source gave me just one definition of getSupport(). So I am kinda lost here.
I am running: gdc (GCC) 4.0.3 (gdc 0.21, using dmd 1.00)
Any suggestions welcome
Bye, rti |

This because dmd defines version(linux) and Bud, seeing this also defines version(Unix). In other words, linux and Unix are the same things in Bud's eyes. _________________ --

Is there a way to combine those version statements? like:
Code: | version(linux || unix)
{
// foo
} |

I'd never tried compiling yage via gdc, but I plan to make it work eventually. I'm not the best at resolving linking errors, and I don't know why gdc has trouble with that particular function. There's nothing that sets it apart from any of the others. Anyone else have ideas?
In the meantime, you should be able to use dmd on linux as a workaround. |

Why would you want to? They are the same thing. It like coding ...
const int ZERO = 0;
if (foo == 0 || foo == ZERO) _________________ --

No, unix != linux.
Anyway. I think i will give dmd a try then.
Thanks for your answers. |

You could also try removing that function and replace all calls to it with false, at the expense of better performance on higher end cards, but dmd`s probably the better option for now. |

Actually, the DerelictSDL issue was fixed in Derelict a couple of weeks ago. Update to the latest trunk and all should be well. _________________ The One With D | The One With Aldacron | D Bits |

Yage with the latest Derelict is now in the trunk. |

I just tried building yage on windows via gdc and I also get the same linking error--it makes no sense. |

The gdc linking error was fixed in the latest commit. In Device.getSupport(), I was redeclaring a static variable with the same name multiple times inside different scopes. Dmd didn't have a problem with it but GDC did. I refactored and it worked. There's now some basic but buggy GDC support in buildme.d. |
