Below is my Makefile:
SIM ?= icarus
TOPLEVEL_LANG ?= verilog
VERILOG_SOURCES += $(PWD)/../hdl/dut.v
VERILOG_SOURCES += $(PWD)/wrappers/ifc_test.v
intr:
rm -rf sim_build
$(MAKE) sim MODULE=ifc_test TOPLEVEL=ifc_test
include $(shell cocotb-config --makefiles)/Makefile.sim
But while trying to run, I'm getting the error as:
make[1]: *** No rule to make target 'sim'. Stop.

I am trying to cross compile a simple hello world program. The cross compiler I am using is for Buildroot Linux on a RPI4. I am trying to do the compilation on my Ubuntu machine.
I get this error:
make[2]: *** No rule to make target '/home/j_sizzle/Documents/Lab11-2/hello1.o', needed by '/home/j_sizzle/Documents/Lab11-2/hello1.mod'. Stop.
make[1]: *** [Makefile:1825: /home/j_sizzle/Documents/Lab11-2] Error 2
make[1]: Leaving directory '/home/j_sizzle/Documents/buildroot/buildroot-2021.11.1-rpi/output/build/linux-custom'
make: *** [Makefile:7: default] Error 2
My Makefile looks like this:
obj-m += hello1.o
KDIR := /home/j_sizzle/Documents/buildroot/buildroot-2021.11.1-rpi/output/build/linux-custom/
PWD := $(shell pwd)
default:
$(MAKE) -C $(KDIR) KBUILD_EXTMOD=$(PWD) ARCH=arm CROSS_COMPILE=/home/j_sizzle/Documents/buildroot/buildroot-2021.11.1-rpi/output/host/bin/arm-buildroot-linux-uclibcgnueabihf- modules
clean:
$(MAKE) -C $(KDIR) KBUILD_EXTMOD=$(PWD) clean
rm -f *~cd
I'm not really sure what I need to do here and I am somewhat new to makefiles so sorry if I am doing something dumb. I do know that this cross compiler works when just compiling a c program, but this is my first time trying to use it for modules.
When I try to compile the hello.c as a driver component, I got an error as follows:
root#ubuntu:/home/steven/Downloads# make

My Makefile is as follows:
ifneq ($(KERNELRELEASE),)
MODULE_NAME = hellomodule
$(MODULE_NAME)-objs := hello.o
obj-m := $(MODULE_NAME).o
else
KERNEL_DIR = /lib/modules/`uname -r`/build

default: modules
modules:
make -C $(KERNEL_DIR) M=$(MODULEDIR) modules
clean distclean:
rm -f *.o *.mod.c .*.*.cmd *.ko
rm -rf .tmp_versions
endif
Can anybody help me to solve this problem?
I have Kernel module sources (for arm) and I would like to compile two different drivers from the same source.
The kernel in compiled with 2 source files and with cross compile.
MODULE_MAME = modulename
SRCS = drv/source.c lib/libsrc.c
OBJS = $(SRCS:.c=.o)
obj-m += $(MODULE_MAME).o
$(MODULE_MAME)-y = $(OBJS)
KDIR := /mykermelsources/
PWD := $(shell pwd)
all:
$(MAKE) -C $(KDIR) ARCH=arm M=$(PWD) modules
clean:
$(MAKE) -C $(KDIR) ARCH=arm M=$(PWD) clean
In one command, I would like to compile 2 modules.
Two choices:
Keeping 3 different Makefiles, one main that will call both other makefiles. One problem with this, I cannot make it working. make -f makefilediff or make --makefile=makefilediff give me an error.
Log:
make -C /mykermelsources/ ARCH=arm M=/home/mychardriver/ modules

endif
SRCS = drv/source.c lib/libsrc.c

How can I build 2 kernel modules from same multiple source files ?
Just faced this issue, and this is what I did:
For each moduleX you want to build, write a Kbuild_moduleX with the targets. Example:
obj-$(MODULE) += MODULE.o
MODULE-y := source.o
Then, in your Makefile_moduleX, do:
all:
cp Kbuild_moduleX Kbuild
make -C /lib/modules/$(shell uname -r)/build M=$(shell pwd) modules
rm Kbuild
This works because the kernel scripts will give Kbuild priority over reading Makefile.
To compile, do make -f Makefile_moduleX
Is it pretty? No. Does it work? Yes.
I am trying to link Lapack library with my Makefile and Fortran 90 code (gfortran), but every time I type : make pkr_test (pkr_test is the name of the code)
I get the following error :
make[1]: * No rule to make target '/usr/ben/models/common/src/fitting.o'. Stop.

I can attach the Makefile and the Makefile. In case it will help you to give me a quick solution. I actually tried to attach it but I didn't manage.

I am trying to link Lapack library with my Makefile and Fortran 90 code (gfortran), but every time I type : make pkr_test (pkr_test is the name of the code) I get the following error :
make[1]: * No rule to make target '/usr/ben/models/common/src/fitting.o'. Stop.
make[1]: Leaving directory '/usr/ben/models/common/src'
Makefile:20: recipe for target '/usr/ben/models/common/src/fitting.o' failed
make: * [/usr/ben/models/common/src/fitting.o] Error 2
The Makefile tries to build the (object) modules specified in MODS variable, including the last one, $(DIR_test)fitting.o.
It does this by doing the equivalent of calling itself, make $(DIR_test)fitting.o. The problem is that your Makefile, and the included Makefile (../../Makefile.in) don't include instructions on how to generate that file, and the implicit make rules don't success either.
As the dependency ($(DIR_test)fitting.o) cannot be built, make cannot build your specified target (pkr_test).
i am trying to learn how to write device driver on linux. I have looked at several online tutorials. They are simple enough but I have problem compiling it. I got a makefile error at the bottom. I have not done anything to the linux-header-2.6.32-27-generic. It is in the state that it was installed. It may be that it has some dependencies but I have no ideas which one. I am not sure what make is expecting.
I would appreciate any help.
Here is my system info.

In the first Makefile, observe the make command that is being executed in the output when you run sudo make (generally sudo is not required to build the modules) :
make make -C /usr/src/linux-headers-2.6.32-27-generic M=pwd modules
In this case, make is searching for a target named 'make'! Remove the $(MAKE) from the Makefile and try. And also M=pwd option is incorrect!
In the second case, the PWD variable isn't defined. You can define it in the Makefile something like this :
PWD := $(shell pwd)
