how to create a C# wrapper for pocketsphinx

[vivian]

Hi! I'm trying include pocketsphinx in my C# project as speech-to-text function using Visual Studio.
1. Should I create wrapper using SWIG, it there any official tool for it?
2. I read the tutorial here https://cmusphinx.github.io/wiki/tutorialpocketsphinx/#pocketsphinx-api-core-ideas
but is the API available on Win10 and can I just directly include the code on VS C# project?
3. I also downloaded the folder for C# here https://github.com/cmusphinx/pocketsphinx/tree/master/swig/csharp can I use the test.cs file for C# project?

Thank you very much! Appreciate your help!!

You can start with learning about swig first and trying simple swig examples:

https://www.technical-recipes.com/2013/getting-started-with-swig-interfacing-between-c-and-c-visual-studio-projects/

Then you can proceed with porting makefile from https://github.com/cmusphinx/pocketsphinx/tree/master/swig/csharp to Windows nmake to compile pocketsphinx dll for C# and then you can use it in c# as demonstrated in test.cs from the same folder.

Thanks Nickolay
I am following the link you gave me. And I'm trying to port the makefile but it return this error

mkdir -p gen
        swig -I.. -I../../../sphinxbase/swig -I../include -I../../sphinxbase/include  -csharp  -dllimport "libpocketsphinxwrap.so"  -namespace "Pocketsphinx" -o sphinxbase.c  -outdir gen ../../../sphinxbase/swig/sphinxbase.i
'swig' is not recognized as an internal or external command,
operable program or batch file.
NMAKE : fatal error U1077: 'swig' : return code '0x1'
Stop.

I solved the above error but another problems occur when it's running this line

gcc -fPIC `pkg-config --libs --cflags pocketsphinx` pocketsphinx.c sphinxbase.c -shared -o libpocketsphinxwrap.so

gcc: error: 'pkg-config: No such file or directory
gcc: error: pocketsphinx': No such file or directory
gcc: error: unrecognized command line option '--libs'

Hi Vivian,
I am facing same issue. Are you able to port sphinx to C# ?
Thanks.
