I am trying to compile a single main file ( in main_decode.c).

 

The project set-up propelry links the sphinxbase library and includes  all the paths of includes . However it reports a link error:

 

The sphinx code uses this structure to establish exports and imports.

 

#ifndef __S3DECODER_EXPORT_H__

#define __S3DECODER_EXPORT_H__

 

/* Win32/WinCE DLL gunk */

#if (defined(_WIN32) || defined(_WIN32_WCE)) && !defined(CYGWIN)

#ifdef S3DECODER_EXPORTS

#define S3DECODER_EXPORT __declspec(dllexport)

#else

#define S3DECODER_EXPORT __declspec(dllimport)

#endif

#else /* !_WIN32 */

#ifdef HAVE_ATTRIBUTE_VISIBILITY

#define S3DECODER_EXPORT __attribute__ ((visibility("default")))

#else

#define S3DECODER_EXPORT

#endif

#endif

 

#if defined(__GNUC__) && __GNUC__ > 2

#define S3DECODER_DEPRECATED __attribute__ ((deprecated))

#else

#define S3DECODER_DEPRECATED

#endif

 

#endif /* __S3DECODER_EXPORT_H__ */

 

 

I triead including the above lines (that apply to Windows) and explicitly defined them for import as well as export. The pragmas were added in the main_decode.c before includes. However, there was no change in linking step (perhaps they are re-set in those includes). However, the search indicates that the definition of the constant occurs only in sphinx3_exports.h

 

One major difference is that the original Visual Studio project definiition was is Visual Studio 6.0 and I have Visual Studio 2008 (that required automatic conversion).

 

I have run out of ideas what coudl be the source of the problem. The output of the build process is given below

 

Thanks

I ultimately recommend you to try pocketsphinx instead of sphinx3. You can learn more about versions of CMU decoders on cmusphinx website:
