eds to drag in the source and header files from the libcelt directory into the
project and define HAVE_CONFIG_H is the project's pre-processor definition.
The tricky part is to build a config.h file. To get it to work on VS some of
the important settings include.
=20
#define CELT_BUILD
#define USE_ALLOCA
#undef VAR_ARRAYS
#undef restrict
#undef HAVE_STDINT_H
#undef inline
#define inline __inline
#define restrict
#undef HAVE_LRINT
#undef HAVE_LRINTF
I have also tested the windows version compiled as fixed point, again without
any problems.
I can supply a config.h and project file on request. black_190 on the domain
hotmail.com.

Hi,
I suggest you try running the test cases in tests/ to see which=20
component you may be having problems with. Also, make sure that you=20
define HAVE_CONFIG_H and that your config.h file includes the following=20
(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=20
I suspect there may just be something wrong with your environment.
Cheers,
Jean-Marc
