Can not compile successfully

[eeyrw]

I just follow the official cross build instruction and met the error like this:

...
*** No rule to make target `fs/cachefiles/xattr.o', needed by `fs/cachefiles/cachefiles.o'.  Stop
...
drivers/char/hw_random/core.c:35:29: fatal error: linux/hw_random.h: No such file or directory
 #include <linux/hw_random.h>
                             ^
compilation terminated.
...

 #include <linux/netfilter/xt_DSCP.h>
...                                    ^

My host linux is ubuntu 14.04 LTS 64bit.

Path:

yuan@yuan-VirtualBox ~> echo $PATH
/opt/xtensa-lx106-elf/bin /usr/local/sbin /usr/local/bin /usr/sbin /usr/bin /sbin /bin /usr/games /usr/local/games /home/yuan/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin

My steps:

Download git repo as zip directly due to my poor network.

Desktop/          firmware/             minicom.log  Templates/ 
Documents/        firmware-master.zip*  Music/       tools/
Downloads/        linux/                Pictures/    tools-master.zip*
examples.desktop  linux-rpi-4.4.y.zip*  Public/      Videos/

I extract (with gui tool) linux-rpi-4.4.y.zip to linux, tools-master.zip to tools, firmware-master.zip to firmware.

cd linux 
KERNEL=kernel7

Which result this:

yuan@yuan-VirtualBox ~/linux> KERNEL=kernel7
fish: Unknown command “KERNEL=kernel7”. Did you mean “set KERNEL kernel7”? For
information on assigning values to variables, see the help section on the set
command by typing “help set”.
KERNEL=kernel7: command not found

I tried command "set KERNEL kernel7". So it create a var call KERNEL with has val of kernel7. Is it the problem caused by fish?

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- bcm2709_defconfig
  HOSTCC  scripts/basic/fixdep
  HOSTCC  scripts/kconfig/conf.o
  SHIPPED scripts/kconfig/zconf.tab.c

  SHIPPED scripts/kconfig/zconf.hash.c
  HOSTCC  scripts/kconfig/zconf.tab.o
  HOSTLD  scripts/kconfig/conf
#
# configuration written to .config

It seems working fine.

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage modules dtbs -j 2
...
I wait for a long time it throws some error mentioned before and compilation stopped.

Please include the exact commands you ran - use the history command if you still have the shell. We cross compile all the time, so there is probably something about your environment or the commands you ran that caused the error.

I have tried a lot ways which don't make it work, feeling so frustrated, and just turn off my virtual machine... So I have retried and update the essential info to the post. Before retrying I ran the command "make mrproper" to clean the working place.

[eeyrw]

I examine the error:
*** No rule to make target fs/cachefiles/xattr.o', needed by fs/cachefiles/cachefiles.o'. Stop
It looks like missing file...

I tried to extract files many times. But the file xattr.c always missed.. weird...

It looks like the problem mentioned here:
#34

[pelwell]

Yes, it looks like xattr.c has got lost somehow.

We have observed that zip downloads can be unreliable, so I would recommend trying to use the git clone method; with the --depth=1 option the download won't be quite so large. I expect that to work as advertised.

[eeyrw]

It's not the faculty of zip file. The unzip has some bug mentioned in this issue:#34
I change to the 7z and it works fine.

Please close the issue if you feel it is resolved.
