bison and yacc compatibility

Robhogg · 04-13-2009, 09:55 AM

I'm trying to compile bash, but make fails with:

"make: yacc: Command not found"

yacc is not available from my repositories (CentOS 5.3), but after a bit of searching, I found a post here saying that yacc was part of bison, which I've now installed. Still no yacc but the man page says:

Quote:

Bison... should be upwardly compatible with input files designed for yacc.

Does this mean that I can simply create a symlink to bison called yacc, and things will work? Tempted to just try it, but scared of terminally breaking things...

Thanks,
Rob

Try this : # 'yum search yacc' .... and get 'byacc'
which is = yacc.

Add. 1 : 'yacc' can be made as a link to bison.

Add. 2 : In rare occasions 'byacc' works better than 'bison'.

Thanks,

I did manage to get it to compile by linking yacc to bison.
