[Q] Issues Compiling Droid Incredible Kernel

[tcberg2010]

Evening All,

I am attempting to compile a kernel for my droid incredible and am running into a problem. I successfully compiled one a few weeks ago, but am trying to refresh so i can learn more. I am using instructions found at:
http://wiki.cyanogenmod.com/index.php?title=Building_from_source,
only changing commands when necessary. I have pulled a working .config from Skyraider 2.2, created the backup and was able to edit it to my liking. For this I decided to leave everything as stock, as my intention was to just compile the stock kernel to help myself learn. When I enter

make ARCH=arm CROSS_COMPILE=$CCOMPILER

,
I receive the following error:

[email protected]:~/androkern/incredible$ make ARCH=arm CROSS_COMPILE=$CCOMPILER 
scripts/kconfig/conf -s arch/arm/Kconfig
  CHK     include/linux/version.h
  UPD     include/linux/version.h

kernel/bounds.c:1: error: bad value (armv5t) for -mtune= switch
make[1]: *** [kernel/bounds.s] Error 1
make: *** [prepare0] Error 2

Being new to compiling would anyone be able to help me understand what this error means. I have not found anything so far that could help me. I was not expecting any issues since I was essential just compiling the Stock Kernel for my own use.

Would someone be able to help me learn what is causing this? Thank you.

you need to do:
export CCOMPILER=${HOME}/mydroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi-

(assuming you pulled everything down in ~/mydroid , otherwise change it to where it is)
then you should be able to compile it

That command did work for me. I was able to compile it. What I would still like to know is what exactly I did when i ran that command? I don't really enjoy mashing in commands when i don't know what they mean.

Basically you created an environmental variable called CCOMPILER that is equal to the location of the cross compiler binaries.

This command would do the same thing:

make ARCH=arm CROSS_COMPILE=${HOME}/mydroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi-

You are just pointing the make file to the location of the cross compiler so that it doesn't use the host compiler by default

+1 Whenever you "export" you're setting an environment variable to something. Then you can verify it by typing: "echo $CCOMPILER" (without quotes) and it should spit that path back at you.

fwiw, you can add that line to your .bashrc and it will always be set for you

Thank you guys, to be honest that answer is a little over my head, but its a nice basis to help me learn more. Really appreciate the quick responses.
