>Description:
As the legions reported unnecessarily to jkh, some people write Fortran
on FreeBSD. It seems that make knows how to build foo.o from foo.f, but
cannot build foo from foo.f. Contrast this behavior with C code; make can
build a single C source file into a binary.
>How-To-Repeat:
I have a simple Fortran program contained in prob1.f. No Makefile is
present in the current directory.
mph124:~/tmp$ ls -l prob1*
-rw-r--r-- 1 hunt users 132 Sep 16 14:06 prob1.f
mph124:~/tmp$ make prob1
make: don't know how to make prob1. Stop
mph124:~/tmp$ make prob1.o
f77 -O -c prob1.f
prob1.f:
MAIN:
>Fix:
As far as I can tell, it should work! /usr/share/mk/sys.mk has these
two rules:
.f:
${FC} ${FFLAGS} ${LDFLAGS} -o ${.TARGET} ${.IMPSRC}
[...]
.f.o:
${FC} ${FFLAGS} -c ${.IMPSRC}
I cannot figure out why the second one works, but the first does not.
