# bison > GNU parser generator. > More information: . - Compile a bison definition file: `bison {{path/to/file.y}}` - Compile in debug mode, which causes the resulting parser to write additional information to `stdout`: `bison --debug {{path/to/file.y}}` - Specify the output filename: `bison --output {{path/to/output.c}} {{path/to/file.y}}` - Be verbose when compiling: `bison --verbose`
