63 | # | |
64 | # Note that Makefile.SH employs a bare yacc to generate | |
65 | # perly.[hc] and a2p.[hc], hence you may wish to: | |
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. | |
75 | # | |
76 | if test "X$byacc" = "Xbyacc" ; then | |
77 | if test -e /etc/yyparse.c ; then | |
78 | : we should be OK - perhaps do a test -r? | |
79 | else | |
80 | cat <<EOWARN >&4 | |

82 | Warning. You do not have a copy of yyparse.c, the default | |
83 | yacc parser template file, in place in /etc. | |
84 | EOWARN | |
85 | if test -e /samples/yyparse.c ; then | |
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. | |
