Hello All
Just discovered something, wanted to share, might be that many out there will be knowing this, for the unknowns sharing this:
We do few source file change and then end up building the entire stuff using "make" command. Mid way through the build we see that a single annoying COMPILE ERROR and see its such a waste of time.
So the ideal thing is to just compile and link only the changed file which will be quick and rest assured FULL the build will succeed. So here's how it is to be done:
In my below example I am building the Sensor file which is in the path, kernel/drivers/hwmon: *The build command is:* make -C ../out/target/product/snowball/obj/kernel/ SUBDIRS=drivers/hwmon ARCH=arm CROSS_COMPILE=arm-eabi-
*Replace the "drivers/hwmon" to your location where the file you modified is present and it builds.*
For eg: venkatr@build1:~/snowball_board_branch_0.0.3/kernel$ vim drivers/hwmon/lsm303dlh_m.c venkatr@build1:~/snowball_board_branch_0.0.3/kernel$ make -C ../out/target/product/snowball/obj/kernel/ SUBDIRS=drivers/hwmon ARCH=arm CROSS_COMPILE=arm-eabi- make: Entering directory `/u/home01/venkatr/snowball_board_branch_0.0.3/out/target/product/snowball/obj/kernel' make -C /u/home01/venkatr/snowball_board_branch_0.0.3/kernel O=/u/home01/venkatr/snowball_board_branch_0.0.3/out/target/product/snowball/obj/kernel/.
CC drivers/hwmon/lsm303dlh_m.o LD drivers/hwmon/built-in.o Building modules, stage 2. MODPOST 0 modules make: Leaving directory `/u/home01/venkatr/snowball_board_branch_0.0.3/out/target/product/snowball/obj/kernel' venkatr@build1:~/snowball_board_branch_0.0.3/kernel$
