64 | # Note that Makefile.SH employs a bare yacc to generate |

66 | # |

67 | # alias yacc='myyacc' |
---|
68 | # |
---|
69 | # Then if you would like to use myyacc and skip past the |
---|
70 | # following warnings try invoking Configure like so: |
---|
71 | # |
---|
72 | # sh Configure -Dbyacc=yacc |

73 | # |

74 | # This trick ought to work even if your yacc is byacc. |

86 | cat <<EOWARN >&4 |
---|
87 | |

88 | There does appear to be a template file in /samples though. |
---|
89 | Please run: |
---|
90 | |
---|
91 | cp /samples/yyparse.c /etc |
---|
92 | |
---|
93 | before attempting to Configure the build of $package. |
---|
94 | |
---|
95 | EOWARN |
---|
96 | else |
---|
97 | cat <<EOWARN >&4 |
---|
98 | |
---|
99 | There does not appear to be one in /samples either. |
---|
100 | If you feel you can make use of an alternate yacc-like |
---|
101 | parser generator then please read the comments in the |
---|
102 | hints/os390.sh file carefully. |
