That did not help.
I recompiled the kernel of the latest 1.4 SDK using ./build.sh and the errpr still persists

Hi,

Has anyone succeed in compiling the "helloword" kernel sample module from the website?

The Faq 19 does not help.

Even if I rebuild the kernel using "./builds kernel" those include/generated/autoconf.h or include/config/auto.conf files which the ../source/kernel/Makefile looks for in the 757.line exists only during the build process.
How can we make them permanent after building the kernel?

Any ideas would be appreciated.
Thanks
