Getting this when trying to "make bzImage"...

Code:

make[1]: *** No rule to make target `kernel/+', needed by `kernel/built-in.o'. Stop.

I just downloaded the kernel source from kernel.org. Then I copied my /boot/config to the kernel src tree .config. Then ran make menuconfig, make 2 tweaks. Then ran "make bzImage" and then got that error from make.

What does it mean exactly?

I haven't worked with Slackware in awhile so I don't know if you will have other issues, but this is what I do on Fedora.

Code:

mkdir ~/build                                # A directory where your build will be built.

make O=/home/name/build/kernel mrproper      #  Replace name with your username.  This will clean up any .o from an old build

copy your config file to .config in your source directory

make O=/home/name/build/kernel oldconfig    # This parses your old config and updates it with new options.

make O=/home/name/build/kernel menuconfig    # Make your 2 tweaks

rm .config in the source directory          # I think your build will sense this and not allow you to build if you don't

make O=/home/name/build/kernel              # This is the build.  It takes awhile to execute

sudo make O=/home/name/build/kernel modules_install install    # This copies your bzImage to the /boot directory

                                                              # Sets up some symbolic links and updates the grub.cfg

Reboot and test.. If you have other problems, please reply to this thread.

Nice, I'll try that.

So the "make" will do both make bzImage and modules correct? At least that's what it looks like in the Makefile.

Yes. It takes a while and it compiles and links all the modules necessary to make the kernel, and it links it together to make bzImage.

Just run make. make help if you want to inform yourself.

Be sure to be sitting in the kernel top source. I never bother with a build directory - too much messing, and the kernel keeps the source clean anyhow.
