yacc Error when building GCC from source tar

yacc Error when building GCC from source tar

[sean yang]

When I build GCC on my Free-BSD box, I met the following error. My yacc is a 
berkeley yacc. Did someone meet this problem before? Can you give some 
suggestion about the error? Thanks,


#which byacc
/usr/bin/byacc
#which yacc
/usr/bin/yacc


#../gcc/configure --prefix=/home/local_compiler/obj-gcc 
--enable-languages=c,fortran
...
#make
....
gcc -c  -g -O2 -DHAVE_CONFIG_H  -I. -I../../gcc/intl 
../../gcc/intl/ngettext.c
byacc --name-prefix=__gettext --output plural.c ../../gcc/intl/plural.y
usage: yacc [-dlrtv] [-b file_prefix] [-o output_filename]
            [-p symbol_prefix] filename
*** Error code 1

Stop in /usr/home/local_compiler/obj-gcc/intl.
*** Error code 1

You should install GNU bison and re-run configure.

You shouldn't need either yacc or bison though if you are building from
a tarball, unless something caused your timestamps to be incorrect.  The
generated files should be included in the tarball.
