Compile your changes- Tutorial(make -j2)

Hi,

I followed the tutorial upto modifying driver on native linux but when I
compiled my changes with the make -j2 command it gave me this:

 YACC    scripts/kconfig/zconf.tab.c
/bin/sh: 1: bison: not found
scripts/Makefile.lib:217: recipe for target 'scripts/kconfig/zconf.tab.c'
failed
make[2]: *** [scripts/kconfig/zconf.tab.c] Error 127
make[2]: *** Waiting for unfinished jobs....
  LEX     scripts/kconfig/zconf.lex.c
/bin/sh: 1: flex: not found
scripts/Makefile.lib:202: recipe for target 'scripts/kconfig/zconf.lex.c'
failed
make[2]: *** [scripts/kconfig/zconf.lex.c] Error 127
Makefile:507: recipe for target 'silentoldconfig' failed
make[1]: *** [silentoldconfig] Error 2
make: *** No rule to make target 'include/config/auto.conf', needed by
'include/config/kernel.release'.  Stop.
make: *** Waiting for unfinished jobs....

then I installed bison and it didn't make the error go away, now I am
stuck. If you could please tell me where the problem is.

Thanking You,
Shreyasi

It seems that you are also missing flex.

The startup of the kernel compilation process is indeed surprisingly
complicated.

You need to install the 'bison' package on your system.

And install 'flex'

It doesn't look like bison is installed.

Try just doing a 'make -j1' to ensure that you are seeing the correct
error messages.

Yes, I had a problem of broken dependencies. Flex and bison weren't
installed.
Thank you!
