It doesn't compile on Ubuntu 16.04

[cibersheep]

After installing `sudo apt install gtk-doc-tools``` to satisfy autgen.sh
After configure, make throws out this error and stops the compilation

Thanks for reporting this! Do you have the yacc program installed? Find out which package to install using apt-file search /usr/bin/yacc.

Thank you!
You are right, I didn't have yacc installed. So, I installed bison... now compiling

Strange, because ./configure should be checking for yacc ... what is actually the text at line 175 of teh file ylwrap?
