There is no rule to make the target `/ Makefile 'needed by the` Makefile'

Question

I am trying to do using a fairly simple makefile. My makefile is called a "Makefile", so I just use the "make" command.

I get this strange error:
make: *** No rule to make target `/Makefile', needed by `Makefile'. Stop.

If, however, I use make -f "full-path-to-makefile"it really works (with odd consequences ...). I have to say that I run all this from the directory where the Makefile is located.

I am working on Mac OSX using tcsh.

Edit:

I work in an LLVM environment trying to compile the pass function, and this is the associated make file:

LEVEL = ../../../
LIBRARYNAME = FunctionName
LOADABLE_MODULE = 1
include $ (LEVEL) /Makefile.common

Any ideas would be appreciated :)

Answer 7

here are my fixes for this problem: ( https://github.com/rust-lang/rust/issues/24887#issuecomment-99391849 )

update src / llvm / Makefile.config.in before starting. / configure

or update x86_64-apple-darwin / llvm / Makefile.config before doing

line 59:

PROJ_SRC_DIR    := $(LLVM_SRC_ROOT)$(patsubst $(PROJ_OBJ_ROOT)%,%,$(PROJ_OBJ_DIR))

upgrade to

PROJ_SRC_DIR    := $(patsubst $(PROJ_OBJ_ROOT)%,$(LLVM_SRC_ROOT)%,$(PROJ_OBJ_DIR))

line 86:

PROJ_SRC_DIR := $(call realpath, $(PROJ_SRC_ROOT)/$(patsubst $(PROJ_OBJ_ROOT)%,%,$(PROJ_OBJ_DIR)))

upgrade to

PROJ_SRC_DIR := $(call realpath, $(patsubst $(PROJ_OBJ_ROOT)%,$(PROJ_SRC_ROOT)%,$(PROJ_OBJ_DIR)))
