[Q] Trying to compile a kernel, getting error

I'm trying to compile a kernel for the Sensation using Tamcore's source but I get an error while compiling (w/o quotes):
"arch/arm/mach-msm/pm-8x60.c: In function 'msm_pm_init':
arch/arm/mach-msm/pm-8x60.c:1261: warning: unused variable 'cpu'
error, forbidden warning: pm-8x60.c:1261
make[1]: *** [arch/arm/mach-msm/pm-8x60.o] Error 1
make: *** [arch/arm/mach-msm] Error 2
make: *** Waiting for unfinished jobs...."
I looked at the line in the file it errors out on (w/o quotes):
"unsigned int cpu;"
I don't know what to do from here since this is my first time compiling an Android kernel, so any help is appreciated.
EDIT: I've solved my problem and my kernel runs fast on JB . This thread is no longer necessary; please delete it.

compile kernel error

Dear friends,
I encountered the trouble of compiling kernel failed.Ten days ago,I compiled it successfully.But today I am failed to do it again.The error is as below:
arch/arm/mm/alignment.c: In function ‘do_alignment’:
arch/arm/mm/alignment.c:298:15: error: ‘offset.un’ may be used uninitialized in this function [-Werror=uninitialized]
arch/arm/mm/alignment.c:720:21: note: ‘offset.un’ was declared here
cc1: all warnings being treated as errors
make[1]: *** [arch/arm/mm/alignment.o] Error 1
My host OS is ubuntu10.04 and the cross-compile is arm-2012.09/bin/arm-none-linux-gnueabi-.
I check it,but some's suggestion is about GCC.I have upgraded it.It is not OK.
Thank you in advance.

Well, the point is "all warnings being treated as errors". "-Werror=uninitialized" makes an error out of what would normally be only a warning.
There seems to be a patch to remove that warning:
lkml.indiana. edu/hypermail/linux/kernel/1209.1/02186.html
(xda recommends that I "answer" some questions, but I can not include links until I have 10 posts. Nice work, xda. Really makes sense, this policy)
But as there may be more warning, I would try to disable that behaviour that warnings are treated as errors. Maybe search for "Werror" in the Makefiles and just remove the whole option?

On an unrelated note that's really old. It should work I guess, but Updating to something more modern may be a good idea regardless whether the build works or not.

[Q] Error compiling CM10.1 (Ubuntu Phone build)

Hey!
I'm working on porting Ubuntu 13.04 for phones to HTC One S, and everything has gone well.... except, well, the compile.
Ubuntu Phone is based on a version of CM10.1 with only the low-level android services required (theres no dalvik) so it should be REALLY simple to port to our device, I have downloaded the Ubuntu Phone repo via git and also used "breakfast ville" to clone the CM10.1 Git, I have also used "repo sync" to get all of the dependencies.
But the error is in the compile, I use ". build/envsetup.sh" to prepare the build environment and then I run "brunch ville".... now this is where the problems begin:
Code:
make: *** No rule to make target `/home/djayc/ubuntu/ville/out/target/product/ville/obj/SHARED_LIBRARIES/libril_intermediates/export_includes', needed by `/home/djayc/ubuntu/ville/out/target/product/ville/obj/EXECUTABLES/rild_intermediates/import_includes'. Stop.
I've done a lot of Googling around, the compile only takes around 30 seconds before it gets to this stage - I presume it must be much longer than that.
There's probably a bunch of errors too but for now I'd just like to get this fatal one out of the way and continue the build before we start the debugging.
Thanks, help is appreciated.

Okay! Progress!
So, I commented out:
Code:
# RIL
BOARD_PROVIDES_LIBRIL := true
in the file device/htc/ville/BoardConfig.mk
This was recommended on Ubuntu Launchpad at https://lists.launchpad.net/ubuntu-phone/msg02822.html
It seems to fix this make error, but another one has popped up :/ (gotta love linux!)
Code:
Import includes file: /home/djayc/ubuntu/ville/out/target/product/ville/obj/SHARED_LIBRARIES/hwcomposer.msm8960_intermediates/import_includes

hardware/qcom/audio-caf/alsa_sound/AudioPolicyManagerALSA.cpp:431:42: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
[email protected]:~/ubuntu/ville$
I copied all of it because the error is about gralloc.msm8960 and it is referenced repeatedly, so maybe this could provide insight as to what the error derives from - wait, actually, I know, I'm missing the framebuffer.o file in gralloc.msm8960_intermediates.... but I DO have a framebuffer.d file in gralloc.msm8960_intermediates, is there a chance that the makefile that is compiling the project is referencing the wrong name of a file (unlikely I'd have thought because it is the offical CM10.1 & Ubuntu Phone environment)?
TL;DR: Is framebuffer.d equal to framebuffer.o, and if not how vital is the file and where would I get it?
I think the answers to those 3 questions would be: not sure, pretty vital (it seems to make the display work!), and the CM10.1 ville repo. Of course, the reason I am documenting this is because I'm not sure! So I'm grateful for any input.
Thanks!

EDIT: There seems to be a different issue each time, I ran brunch ville again and it gave me a metric ton of errors about qcom audio.... :/

[Completed] Help compiling SGH Hercules kernel for porting kali nethunter

Hi everyone!
I own the Samsung Galaxy S2 T989 A.K.A. Hercules
running cm 12.1 unofficial Sultan Hercules based on android 5.1.1 (Lollipop)
which has sultan-kernel-celox.
I am actually trying to port kali nethunter, a set of tools for pentesting (Awesome)
Running Kali linux 2.0 32 bits in my notebook. I have installed all the dependencies described in:
https://github.com/offensive-security/kali-nethunter/wiki/Porting-Nethunter
I am using the next rom:
http://forum.xda-developers.com/galaxy-s2-tmobile/development/rom-aosp-lollipop-preview-t2931716
I also read the Develop Now guide to understand a bit better.
So the problem is when I run the " make" command in the sultan-kernel-celox kernel source directory and using " make Sultan_hercules_defconfig" which is inside /arch/arm/configs .
the error I am getting is:
CHK include/linux/version.h
CHK include/generated/utsrelease.h
make[1]: 'include/generated/mach-types.h' is up to date.
/bin/sh: 1: Syntax error: "(" unexpected
/root/arm-stuff/kali-nethunter/sultan-herc/./Kbuild:35: recipe for target 'kernel/bounds.s' failed
make[1]: *** [kernel/bounds.s] Error 2
Makefile:989: recipe for target 'prepare0' failed
make: *** [prepare0] Error 2
So with my very limited knowledge about development and scripting check the Kbuild file at line 35 but I can't understand, I have also "googled" about the error I am getting but without luck, I also have tried with other sources kernel I have found but it seems to be the same message.
So please help me to figure what am I doing wrong or which kernel source should I use. I hope someone with so much more experience than me would help me with this issue to finally getting the nethunter tools.
Thanks in advance

Hi and thank you for using XDA Assist
I think you should ask over here about your problem. I'm sure you will get an answer soon
Good luck !

Problem while compiling recovery

So I just started developing a recovery for a phone that has no support from any other developers, and basically I need to do all the stuff from 0. I follow some guides, I read some forums on the internet and hope I can make it (it's my first time developing something for Android). But for now I have this problem and I can't find it anywhere along with the proper solution (maybe I haven't searched enough). Every time I type make recoveryimage in the terminal, it is working for like 30 seconds, and then a error like this appears:
Code:
target SharedLib: libc (/home/cosinus/Workspace/X3_Soul-CM12.1/out/target/product/X3_Soul/obj/SHARED_LIBRARIES/libc_intermediates/LINKED/libc.so)
[COLOR="Red"]/home/cosinus/Workspace/X3_Soul-CM12.1/out/target/product/X3_Soul/obj/STATIC_LIBRARIES/libc_common_intermediates/libc_common.a([COLOR="DarkRed"][B]gethnamaddr.o[/B][/COLOR]): error adding symbols: File in wrong format
collect2: error: ld returned 1 exit status
make: *** [/home/cosinus/Workspace/X3_Soul-CM12.1/out/target/product/X3_Soul/obj/SHARED_LIBRARIES/libc_intermediates/LINKED/libc.so] Error 1
#### make failed to build some targets (01:02 (mm:ss)) ####[/COLOR]
(In my noobness) I tried to delete all the files that generates the error, in this case, gethnamaddr.o, but there are too much files, and I don't even know why I need to delete every single file that ends with *.o extension and if it's a good solution. I saw that everytime I delete a file that returns an error, the file is generated again, but after it's generated, it won't return any error. So I tought that maybe the *.o files are corrupt, and "make" generates them correctly.
Now that I told you the story, I'm asking:
Is it normal that I have so many errors because of *.o files?
How can I solve it?
The phone: Allview X3 Soul (I heard it's a clone of Gionee S6)
Chipset: MT6753
