I have a configure.in which checks for lex/flex with
AM_PROG_LEX. When I run with flex/lex NOT installed, I
get this output.
checking for flex... no
checking for lex... no
./configure: flex: command not found
checking for flex... lex
checking for yywrap in -ll... no
checking lex output file root... ./configure: lex:
command not found
configure: error: cannot find output from lex; giving
up
My question: how do I get configure to just check for
it, and then only WARN, not produce an error?
Dan.
