Hello!
I'm trying to bootstrap bison to start hacking on it. I just did it
successfully on a computer, but on another one, it's not working.
I have a bison version 3.0.4 installed, and after cloning, running
bootstrap, configure and make, it fails to generate the src/scan-code.c
file.
When I run
$ bison -y ../src/scan-code.l -o src/scan-code.c
it fails because it doesn't recognize %option:
../src/scan-code.l:20.1-7: error: invalid directive: ‘%option’
%option debug nodefault noinput nounput noyywrap never-interactive
Any idea why that happens? Is it because my bison is too old? In which
case, where can I download a (pre-compiled) newer one, for linux (a
debian-like)?
Thanks,
