Hi,
I created a Makefile as Greg suggested but even then it doesnt seem to work
and now it seems to be giving me this error.
The Makefile that I have is as follows:
/**********************************************************************************************************************/
myhome=/home/roaan
compiler=${myhome}/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin
moduledir=/home/roaan/junk
obj-m := hello.o
all:
make ARCH=arm CROSS_COMPILE=${compiler}/arm-eabi- -C
${myhome}/mydroid/common/kernel M= ${moduledir}/ modules
The error that i seem to get is as follows:
make[1]: Entering directory `/home/roaan/mydroid/common/kernel'
make[1]: Nothing to be done for `/home/roaan/junk/'.
make[1]: *** No rule to make target `modules'. Stop.
make[1]: Leaving directory `/home/roaan/mydroid/common/kernel'
make: *** [all] Error 2
I have a module called as hello.c in folder /home/roaan/junk and Makefile is
also in the same folder. Also I didn't understand the usage of M=
${moduledir}/ modules
and what is modules used for here.
Thanks,
Rohan.
