A problem with compiling

[atimin]

I tried to compile the sources for Cortex-M4.
It's my first attempts and I really confused... I started with `make menuconfig' where I disabled MMU-options and chose STMicro STM32 processor. Then I lunched 'make' and got these errors.

I use CodeSourcery G++ Lite toochain. Host Ubuntu 14.04.
Thanks a lot for your help.

Aleksey,

• Emcraft kernel tree on GitHub doesn't include configuration files for
  STM32. Only customers of our products receive sample projects with the
  kernel configuration files for the given BSP.
  However it's not so hard to figure out what options need to be enabled.
  Git history provides sufficient information on that.
• We recommend to use CodeSourcery arm-2010q1 for building. The
  download link is available on the Emcraft Site.

Regards,

Sergei Poselenov,
