To change the language, modify the 
flex file "scanner.l" and the bison file "parser.y".

Open an MS-Dos command line interface.
Type the following 
cd C:\mypath\flexbison\flex scanner.l
cd C:\mypath\flexbison\bison parser.y
to generate the two files :  "lex.yy.c"  and  "parser.tab.c".

Put these two files in the directory of your QT project.
