While running a makefile in gcc 4.1.2 (linux 5), I got the following error
make: yacc: Command not found
By googling, I came to know that this
I ran into a similar issue on RHEL7.
Find where bison is:
$:which bison */bin/bison*
Create symlink to bison from yacc:
sudo ln -s /bin/bison /bin/yacc
And that should solve the problem.
