I have a massive problem with bisonc++'s compiler: The error messages are garbage. It's really hard for me to find the problem, when all it says is Line 63: 2 Reduce/Reduce conflict(s) (line 63 is the last line of the code). Is there a way, a switch or anything to make bisonc++ also return the rules that cause the conflict? Any verbose error reporting? Thank you!
According to the bisonc++ man pages, you can request a detailed output that gets written into a .output file with the -V switch.
- --verbose (-V)
Writes a file containing verbose descriptions of the parser states and what is done for each type of look-ahead token in that state. This file also describes all conflicts detected in the grammar, both those resolved by operator precedence and those that remain unresolved. It is not created by default, but if requested the information is written on .output, where is the grammar specification file passed to bisonc++
