I have installed the LTIB toolchain on Fedora 16. I am trying to add an Module in the Kernel using LTIB, Seeking your help. Please help me in solving the Problem and Correct the Process. 1. ./ltib -m prep -p kernel [decompressing the Kernel]. 2. ./ltib -m shell [Entering in shell mode ] 3. I have created a folder under the directory /ltib/rpm/BUILD/test 4. Copied two files in the folder .c and Makefile attached herewith. 5. Now Cd to /ltib/rpm/BUILD/test 6. make V=1 ARCH=ppc After Executing this command i get Error. Error Log : address@hidden ~]$ cd /home/Admin/Document/MPC8641d/Install/ltib-mpc8641hpcn-20080117/ address@hidden ltib-mpc8641hpcn-20080117]$ pwd /home/Admin/Document/MPC8641d/Install/ltib-mpc8641hpcn-20080117 address@hidden ltib-mpc8641hpcn-20080117]$ ./ltib -m shell Entering ltib shell mode, type 'exit' to quit LTIB> pwd /home/Admin/Document/MPC8641d/Install/ltib-mpc8641hpcn-20080117 LTIB> cd rpm/BUILD/test/ LTIB> make V=1 ARCH=ppc make -C ../linux-2.6.23 M=/home/Admin/Document/MPC8641d/Install/ltib-mpc8641hpcn-20080117/rpm/BUILD/test make[1]: Entering directory `/home/Admin/Document/MPC8641d/Install/ltib-mpc8641hpcn-20080117/rpm/BUILD/linux-2.6.23' test -e include/linux/autoconf.h -a -e include/config/auto.conf || ( \ echo; \ echo " ERROR: Kernel configuration is invalid."; \ echo " include/linux/autoconf.h or include/config/auto.conf are missing."; \ echo " Run 'make oldconfig && make prepare' on kernel src to fix it."; \ echo; \ /bin/false) ERROR: Kernel configuration is invalid. include/linux/autoconf.h or include/config/auto.conf are missing.
