Bug #1361: Configure fails to recognize the absence of bison

• Status: Rejected
• Assignee: -

• ruby -v: ruby-1.9.1-p0.tar.gz

=begin
There is a line "YACC = bison" in Makefile.in; but configure fails to recognize the absence of bison

Bison is NOT installed by default on FreeBSD, resulting in the following error when "make"ing:

---

bison -d -o y.tab.c parse.y
gmake: bison: Command not found
gmake: *** [parse.c] Error 127
*** Error code 2

Stop in /root/_build/ruby.

Desired functionality:

• configure recognizes the absence of bison and falls back to yacc

Less desired functionality:

• configure recognizes the absence of bison and downloads and complies it in a temporary directory within the working directory tree

Least desired functionality:

• configure recognizes the absence of bison and notifies the user of inability to continue.

Why do you need to make parse.c, which is included in the
tarball?

Ruby 1.9 needs bison to create pure parser. Or yacc on FreeBSD
can generate it?

Least desired functionality:

• configure recognizes the absence of bison and notifies the user of inability to continue.

The message from make is very clear, isn't it?
