[CELT-dev] Getting CELT to work under Windows

[Jean-Marc Valin]

Hi,

I suggest you try running the test cases in tests/ to see which 
component you may be having problems with. Also, make sure that you 
define HAVE_CONFIG_H and that your config.h file includes the following 
(that's my guess since I don't have a Windows dev environment):

#define CELT_BUILD
#define USE_ALLOCA
#define inline __inline
#define restrict

I know there's a bunch of people using CELT successfully on Windows, so 
I suspect there may just be something wrong with your environment.

Cheers,

	Jean-Marc
