Re: [eclipse-users] embebing prolog in C++

Hello,

No, I am sorry. I am not that manou. When I start writing my name in this way
I thought I would be the only... but then I realise that no,... ;)

For use chr2pl you have to:

1) load the library: lib(chr)
2) execute the command: chr2pl(fileWithCHRExtension)
3) compile the Prolog file generated: [fileGenerated].

fileWithCHRExtension must be the prlog constraints file and the file generated 
will have the same name but with pl extension.

Try it ;)

Good luck.

Cheers,
·_· manou
