I'm trying to compile a sample kernel module (test.c) on my Arch linux just typing make in the directory with source and Makefile.
It creates empty folder .tmp_versions and empty files Module.symvers and modules.order, but no .ko
I also tried to compile it under virtual machine with Ubuntu, but I have absolutely the same output. Samples were from the Internet (2 ones).
What I should do else to compile it?
Makefile:
obj−m += test.o
default:
$(MAKE) -C /lib/modules/$(shell uname -r)/build SUBDIRS=$(PWD) modules
clean:
$(MAKE) -C $(KDIR) M=$(PWD) clean
But it shows me:
make -C /lib/modules/4.18.14-arch1-1-ARCH/build SUBDIRS=/home/hime/Documents/module modules
make[1]: Entering directory '/usr/lib/modules/4.18.14-arch1-1-ARCH/build'

I'm trying to generate an RPM with a makefile, the behavior I'm expecting from the makefile is the following:
If RPM doesn't exist and the sources are not yet prepared, go ahead and do both: generate sources and then the RPM
If RPM already exist but the sources changed, go ahead and prepare the sources and generate the RPM once again
If the sources haven't changed and the RPM already exist don't do anything
However, right now the behavior I'm getting from the makefile below is not quite the way I want it, as it recognizes whether the RPM exist but when it comes down to the sources it doesn't really recognize that they already exist.
Here's the makefile:
SHELL = /bin/bash
.SHELLFLAGS = -o pipefail -c
COLORIZE := 2>&1 | sed -re "s/^(Executing|Wrote)(.*: )/"$$'\E'"[32m\1\2"$$'\E'"[0m/g" \
-e "s/(error[s]?)/"$$'\E'"[31m\1"$$'\E'"[0m/ig" \
-e "s/(warn|warning)/"$$'\E'"[33m\1"$$'\E'"[0m/ig"
SPEC := $(shell find . -name \*spec -printf '%f' -quit)
ARCH := $(shell rpm -q --qf '%{arch}' --specfile $(SPEC))
DIST := .el
NAME := $(basename $(SPEC))
RELEASE := $(shell rpm -q --qf '%{release}' --specfile $(SPEC) | cut -d. -f1)
VERSION := $(shell rpm -q --qf '%{version}' --specfile $(SPEC))
BUILDDIR := ./rpm-build
RPM := $(BUILDDIR)/RPMS/$(ARCH)/$(NAME)-$(VERSION)-$(RELEASE)$(DIST).$(ARCH).rpm
RPMBUILD := rpmbuild --define "_topdir %(pwd)/$(BUILDDIR)" \
--define "_source_filedigest_algorithm md5" \
--define "_binary_filedigest_algorithm md5" \
--define "_source_payload w9.gzdio" \
--define "_binary_payload w9.gzdio" \
--define "_sourcedir %{_topdir}/SOURCES" \
--define "_target_os linux" \
--define "dist .el"
SOURCE0 := $(BUILDDIR)/SOURCES/$(NAME)-$(VERSION).jar
.PHONY: all clean
all: $(RPM)
$(BUILDDIR):
#mkdir -p $(BUILDDIR)/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS,TEMP}
$(SOURCE0): $(BUILDDIR) $(SPEC)
spectool -g -C $(BUILDDIR)/SOURCES $(SPEC)
$(RPM): $(SPEC) $(SOURCE0)
#echo -e "Building $(RPM)"
$(RPMBUILD) -bb $< $(COLORIZE)
clean:
#- $(RM) -rf ./$(BUILDDIR)
Is there anything I'm doing wrong for managing the sources, I just don't want them to be prepared everytime I run a make command ?
You should never have a target with a directory as a prerequisite, because directory timestamps are updated at unusual times. I shouldn't say "never"; it can be very useful but it means something quite different than what you think.
You can try using an order-only prerequisite for this:
$(BUILDDIR):
#mkdir -p $(BUILDDIR)/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS,TEMP}
$(SOURCE0): $(SPEC) | $(BUILDDIR)
spectool -g -C $(BUILDDIR)/SOURCES $(SPEC)
Or you can just put the mkdir inside the recipe:
$(SOURCE0): $(SPEC)
#mkdir -p $(BUILDDIR)/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS,TEMP}
spectool -g -C $(BUILDDIR)/SOURCES $(SPEC)
Note, you're using bash-specific issues here ({}). If you want to be portable you need to add:
SHELL := /bin/bash
to your makefile.
I have a makefile like this:
default:
%:
#$(MAKE) -i -C subdir1 $*
#$(MAKE) -i -C subdir2 $*
#$(MAKE) -i -C subdir3 $*
#$(MAKE) -i -C subdir4 $*
#$(MAKE) -i -C subdir5 $*
The basic concept is that I have 5 (or more) sub projects which I will call make on sequentially. I use "-i" flag so that the make can continue to the end and the "-C dir" flag to call make in a sub-directory.
So, lets say that sub project 2 and 5 are failing, then at the end I want to be able to print something like:
3 projects built ok, 2 projects have errors.
So I think I want a counter of some sort, but I have no idea how I can set/increment it on an error. Any ideas?
As every call to $(MAKE) spawns its own subprocess, I can't think of a way to record these numbers easily with an ordinary make variable. You can, however, log the return value of each invocation to a (possibly hidden) file and then grep for your build stats like this:
errLog = .errLog
default:
%:
#$(MAKE) -i -C subdir1 $*; echo $$? > $(errLog)
#$(MAKE) -i -C subdir2 $*; echo $$? >> $(errLog)
#$(MAKE) -i -C subdir3 $*; echo $$? >> $(errLog)
#$(MAKE) -i -C subdir4 $*; echo $$? >> $(errLog)
#$(MAKE) -i -C subdir5 $*; echo $$? >> $(errLog)
#echo "`grep -c '^0' $(errLog)` built ok, `grep -c '^[^0]' $(errLog)` have errors."
Note that the first output redirection must be a single > to overwrite previous return codes in the file, while all others should be two > to not overwrite the file content.
I am trying to analyze the following makefile and reproduce its "behavior" step by step.
Although I type "make all" it seems this makefile skips the "all:" line and jumps straight to "build/*.o" (hence the echo's).
The file and its corresponding output:
TOOLCHAIN ?= arm-none-eabi-

rm -f kernel7.list kernel7.img kernel7.syms
rm -f kernel7.elf kernel7.hex kernel7.map

echo -e "cleaning \n"
I tried to replicate this behaviour myself with a tiny piece of code. But it doesn't seem to work:
SOURCES = Demo/Drivers/rpi_irq.c \
Demo/Drivers/rpi_gpio.c
OBJECTS = $(patsubst %.c,build/%.o,$(SOURCES))
.PHONY: all clean
all: $(MOD_NAME)
echo "making all"$(SOURCES)
$(MOD_NAME): $(OBJECTS)
echo "MOD_NAME"
build/%.o:%.c
mkdir -p $(dir $#)
arm-none-eabi-gcc -march=armv7-a -mcpu=cortex-a7 -mfpu=neon-vfpv4 -mfloat-abi=har $< -o $#
As you can see thanks to the echo's my code just doesn't even build my source code. I'd expect it to go from all->MOD_NAME->build. (This is all the output I get)
So my questions are:
How does the makefile I am analyzing manage to go straight to build/*.o?
Why does my implementation, which I think should do the same doesn't even compile my source code?
The Makefile that you copied contains 2 rules for "all".
The first depends on $(MOD_NAME) which might be empty.
The second rule depends on multiple files "kernel7.*" which themselves depend on "kernel7.elf".
Finally "kernel7.elf" depends on $(OBJECTS).
This last rule is responsible that all your source files will be compiled.
The first rule with $(MOD_NAME) does not need to cause any compilation at all.
In your own Makefile you only have a rule for "all" depending on $(MOD_NAME).
If $(MOD_NAME) is empty in your Makefile as well, you do not have any dependency for "all" at all.
If "all" does not depend on anything, no source files will be compiled.
To solve your problem you need to provide some content for $(MOD_NAME).
all is trying to build $(MOD_NAME), which has dependencies of $(OBJECTS), which it is trying to build.
There are two all's here, which is a problem.
I Cross compiled cups 1.7.0 for sitara arm linux 6
I followed
./configure --host=arm-linux-gnueabihf --disable-gssapi --prefix=/media/rootfs
make
make install
All cups related files are automatically saved in sd card ,
but it shows error on typing cupsd command and not starting cups server
cupsd: Child exited on signal 1.
On checking /etc/cups/cupsd.conf, several paths in the configuration files are
/media/rootfs/var/run/cups/cups.sock
instead of
/var/run/cups/cups.sock
1)how to install this compiled cups to target board without --prefix?
2)Is there any step missing for cross compilation?
Any help will be thankfull.

DSTROOT=/media/rootfs option in make install is the solution for cups.
./configure --host=arm-linux-gnueabihf --disable-gssapi --libdir=/usr/lib
make
sudo make install DSTROOT=/media/rootfs
Dont use --prefix.
cupsd: Child exited on signal 1.
This error is due to hardcoding of paths.You can avoid it by placing your installed executables in same directory by creating it in your rootfs.
There are two way to avoid above 1) while configuring the source-code give the prefixsome other folder like $HOME/cups so that this will be a standalone. create directory by the same name $HOME/cups same as you prefix in your rootfs copy this standalone executable as u mentioned in prefix.
e.g --prefix=/home/vinay/cups then make same directory path in your rootfs /home/vinay/cups and copy all your executables here.
For second way i am not sure it will work or not since for qt project i tried and its worked.By Use of sysroot
2)provide option --sysroot=/media/rootfs --prefix=/media/rootfs so that while executing ypur executables executable look correctly search the path with help of sysroot.

I'm getting the following error:

From what I understand it is a white space/tabulation/non unix character problem in the last lines of the makefile (after install:). But even trying to delete all spaces and replacing with tabulation I didn't manage to run the makefile properly. The code comes directly from a programming book I'm reading and is an example. Any help appreciated!
You're missing a trailing slash on your else under the install rule. It should be:
install: myapp
#if [ -d $(INSTDIR) ]; \
then \
cp myapp $(INSTDIR);\
chmod a+x $(INSTDIR)/myapp;\
chmod og-w $(INSTDIR)/myapp;\
echo "Installed in $(INSTDIR)";\
else\
echo "Sorry, $(INSTDIR) does not exist";\
