Compilation issue

[madhavan kumar]

hi guys,

      i tried to run make command on sysplay network drivers code samples with my linux kernel versioned 3.17.4. Got a compilation error,
fatal error: asm/bitsperlong.h: No such file or directory

this error i fixed by manually copying bitsperlong.h from arm-generic to arm folder, i.e. from /usr/src/linux/include/asm-generic to #{LINUX_SRC}/include/asm

but then, this error gets repeated for other header files as,

fatal error: asm/preempt.h: No such file or directory
fatal error: asm/current.h: No such file or directory
fatal error: asm/errno.h: No such file or directory

am i missing any makefile configuration (or) is linux kernel 3.17+ not the right version to go with sysplay examples?

thanks,
saravana

Hi Saravana,
    You can use kernel version 3.17 with SysPlay examples.

    The problem seems to me is that your kernel is not configured. Try make oldconfig and make modules_prepare in the kernel folder, before trying to build the samples code.

hi Anil,

'make oldconfig throws
  make: *** No rule to make target `oldconfig'.  Stop.

'make modules_prepare complains
  make: *** No rule to make target `modules_prepare'.  Stop.

and when i go & search for these targets in my make_file, i don't see them. and i am sure, i didn't make much of a change in my KBuild makefile.

note: makefile from Sysplay/ USB & Network Drivers Workshop downloads attached.

Hi Saravana,
    Please type the commands in the kernel source folder, not in the SysPlay code.

/home/sk/code/kernmod/ws/bd,nd_templates/PCIDriver/expt_drv.c:301:1: fatal error: opening dependency file /home/sk/code/kernmod/ws/bd_nd_templates/PCIDriver/.expt_drv.o.d: No such file or directory

my cmd-------------- make (inside sysplay network drivers folder)

Possibly change the owner & permissions of the driver directory, correctly.
