Package: make
Version: 3.81-2
Hello,
I've got a simple Makefile containing the following two lines for
generating a C file from a flex file:
test.c: test.lex
$(FLEX) -o test.c test.lex
It seems that the $(FLEX) variable does not work.
$ make
o test.c test.lex
make: o: Command not found
make: [test.c] Error 127 (ignored)
Using $(LEX) instead solves the problem ('lex' is a symlink to 'flex'
anyway, at least on my system).
$ make
lex -o test.c test.lex
This is an easy workaround, but this is confusing since the 'make'
manual clearly mentions both $(FLEX) and $(LEX).

Apologies, but I had misunderstood the GNU make manual.
Indeed, Section 14.4.2 [1] talks about the variables that should be used
by the utility programs, but it does not mention how they are or should
be initialised.
Section 10.3 [2] gives a list of which of these variables are implicitly
defined with default values. LEX is one of them, FLEX is not.
Thus, I'm closing this bug report.
Regards,
Bruno.
