kernel compilation: new modules

iggi · 12-03-2007, 09:26 AM

Hi,

I was reading about compiling the kernel when I bumped onto NTFS support. Have some questions regarding this topic:

1) Say I don't want to download the 'ntfs.ko' file (which works perfectly by the way)... If I wanted to do it myself and ran 'make menuconfig', selected NTFS support as module would I also need to download the source code seperately or is it already available? Or to rephrase: are the 'NTFS' options in menuconfig always available regardless whether you have the necessary source files?

2) Whenever I try to do a make in the "/usr/src/kernels/2.6.18-53.el5-i686" directory... I get this kind of output:

Code:

[root@localhost 2.6.18-53.el5-i686]# make modules
scripts/kconfig/conf -s arch/i386/Kconfig
#
# configuration written to .config
#
  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h
make[1]: *** No rule to make target `arch/i386/kernel/msr.c', needed by `arch/i386/kernel/msr.o'.  Stop.
make: *** [arch/i386/kernel] Error 2

[root@localhost 2.6.18-53.el5-i686]# make dep
*** Warning: make dep is unnecessary now.
[root@localhost 2.6.18-53.el5-i686]# make bzImage

  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h
make[1]: *** No rule to make target `init/main.o', needed by `init/built-in.o'.  Stop.
make: *** [init] Error 2

What does it mean? It stops me from compiling eg. the ntfs module or even tweak some kernel options...

Thanks again guys, really apreciate your help!

Hi,

A LQ search would have given you several explanations.

evilDagmar has defined the options very well.

When you do a 'menuconfig' you are setting up for a '.config' for the session that will create the object files. Yes the options are there for you to select within the menuconfig session. This just a session that you use to create the .config file that will be used to direct the compiler.

I refer you to the 'Kernel-HOWTO'.

Also 'Compiling the Linux Kernel' would be another guide. These links and others can be found in the 'Slackware-Links' . If you look at the 'Linux Kernel section', you will find other useful links about the kernel.

Ok, thanks... missed that post (interesting to read). I know menuconfig generates the .config file. I only wonder whether everything listed is by default provided in the kernel 'package' you download. Eg. can I add NTFS support (=listed) as a module without downloading it's source code seperately?

You can load the module if it was made available at the compile session. If you are referring to using the 'NTFS-3g' then you will need to get the 'NTFS-3G' Slackware package, along with the FUSE Library package. This will allow you to do r/w with a NTFS.

These links and others are available from 'Slackware-Links' .
