Hi,

during the few days looking into the code I've got some questions and maybe one of the devs can answer them:
1) libcmyth: It's supposed to load it as dll and windows complains if it isn't there but to compile it corectly I have to add the static .lib otherwise it complains about missing dependencies. What do I miss here or why is the lib still needed?

2) I've tried to compile libshout which works with the sources provided but when I link it to xbmc_pc it complains about missing dependencies concerning libmad which is also supposed to be loaded as dll!? Maybe the same topic as 1)

3) todays revision broke the windows build due to missing dependencies to some _Py.. methods. Maybe also explainable with 1) and 2)?

Thanks for your help.

1) sounds very weird. the only lib needed would be a implib IF you link the program to the dll (which there's no need to do - it's dlopen'd (ehm, cant recall the win32 function name, OpenLibrary or something?)
2) the libshout stuff is done for linux where we explicitly link the main program to libmad (-lmad). so you'd need to link to libmad on win32 as well - either the dll or the .lib doesnt really matter
3) don't think so, that's most likely caused by something in rev 11855

Thanks for the reply. Maybe a stupid question but how do I link to a dll? Also with the pragma command or with the project settings in the linker tab?

Btw is there a chance to get a precompiler definition for this build something like _WIN32PC or should I still use:

Code:
#if defined(_WIN32) && !defined(HAS_XBOX_HARDWARE)

?

you can definitely get a preprocessor token - just make sure you only stuff the windows only things within it and not shared windows/xbox. dll's should be somewhere in project settings.

Hey maybe back to 3) Big Grin

I got it compiled by reverting

Code:
#define FUNCTION(function) void* (__cdecl* p_##function)();

in XBPythonDll.cpp to

Code:
#define FUNCTION(function) void* (__cdecl* p_##function)(); void* function() { return p_##function();}

for the windows build.
Fine, now it complained about not finding Q:\system\python\python24.zlib. Here I had to change

Code:
if (access(strFile, 0) != 0) // did this ever work under Linux?

in XBPython::FileExist to

Code:
if (access(_P(strFile), 0) != 0)

But now I'm stuck and seeking for help Huh

When trying to load a script I get the following log:

Code:

and xbmc dies with an unhandled exception in dbgheap.c in line 359

Code:

if (!(*_pfnAllocHook)(_HOOK_ALLOC, NULL, nSize, nBlockUse, lRequest, szFileName, nLine))

Any ideas?

Hi vulkanr,
the older revision of XBPythonDLL.cpp worked better but still not correctly. But as you said I see no other change to the python library.
No I get the error message in the log that python can't import some libraries:

Code:
INFO:   File "E:/Coding/Windows/xbmc_sdl/XBMC_run/Xbmc/scripts/Tetris/default.py", line 9, in ?

INFO:

That could possibly be path related maybe??

**WiSo** · 2008-03-06, 09:51

Do you think so? I looked for the modules and couldn't found them. I assume they are in the library so path shouldn't matter.
To be honest I didn't dig deeper until now. Just wanted to ask if someone already had this problem.

**WiSo** · 2008-03-06, 16:13

J you're right. The libraries are referenced in emu_msvcrt.cpp and since q: is internally mapped they aren't found.

**WiSo** · 2008-03-07, 00:39

I'm stuck for now. I put in a stupid error by working not clean with translate path (mixed slashes and back slashes) which screws something up. After cleaning this up python still can't find the libraries out of python24.zlib.
