Sphinxbase (Sphinx3) Compilation Errors

[Ruben Gutierrez]

Hi, everyone -

I've successfully compiled SphinxTrain using Cygwin and gcc 3.4.4-3. Now, I'm having problems with sphinxbase. At first, trying to compile sphinxbase gave an error about the fact that Python was compiled using Visual Studio 2003. The solution was to add "-c mingw32" to the "setup.py build" command in the Python makefile. Then, I received an error regarding an invalid ld_version value. I fixed that by changing the regular expression which checks the version in the cygwinccompiler.py lib file. Now, when I try to compile sphinxbase, I receive several "undefined reference" errors:

I verified the include line in the makefile is correct, and that the header files exist with the appropriate references which the compiler says are undefined. Can anybody help?

Thanks,

Just install Linux or use Visual Studio project which is distributed with pocketsphinx to compile it on Win32. Don't bother us with Cygwin please :)

Alternatively, look on the file sphinxbase_export.h:

/ Win32/WinCE DLL gunk /

if (defined(_WIN32) || defined(_WIN32_WCE))

if defined(SPHINXBASE_EXPORTS) / Visual Studio /

define SPHINXBASE_EXPORT __declspec(dllexport)

elif defined(CYGWIN) / Disable this on Cygwin, it doesn't work /

define SPHINXBASE_EXPORT

else

define SPHINXBASE_EXPORT __declspec(dllimport)

endif

else / !_WIN32 /

define SPHINXBASE_EXPORT

endif

to avoid imp errors you need to remove define __declspec(dllimport), it causes problems. Most probably cygwin is not detected properly on your system.
