Compiling custom modules... failed to insmod

Hi,
I am trying to make custom mtd module, to expand the mtd devices to read whole nand and i am using as an example msm_nand.c
So what i have done is added a few devices to mtd partition and compiled. But at the compilation ld says msm_dmov_exec_cmd in not found.. Does not sound good, because original msm_nand.c compiled good as well as the whole kernel.
Could someone help me?
Here is the code i added, i left last lines from the original and my addition due to the code length restriction here:
Code:
/* drivers/mtd/devices/msm_nand.c
.....
msm_nand_release_ex(&info->mtd);
dma_free_coherent(/*dev*/ NULL, SZ_4K,
info->msm_nand.dma_buffer,
info->msm_nand.dma_addr);
kfree(info);
}
return 0;

And also i get in dmesg weird message that my kernel version string is wrong, though i used same kernel except the last modification string. And i can't find any other kernel..
Thanks guys!

you should edit the Makefile and set
EXTRAVERSION = <your kernel version>.

Yes i managed to bypass it but the insmod then says msm_dmov_exec_cmd is not found..
Weird..

[Q] Error while compiling a ROM.

I'm getting this error while compiling a CM12 based ROM.
Code:
frameworks/native/libs/ui/GraphicBufferMapper.cpp:52:43: error: definition of implicitly-declared 'android::GraphicBufferMapper::~GraphicBufferMapper()'
GraphicBufferMapper::~GraphicBufferMapper();
There is a "^" under the "()" symbol.
The code is as follows (note: It is a shortened code as the whole code is huge).
Code:
ANDROID_SINGLETON_STATIC_INSTANCE( GraphicBufferMapper )
GraphicBufferMapper::GraphicBufferMapper()
: mAllocMod(0)
{
hw_module_t const* module;
int err = hw_get_module(GRALLOC_HARDWARE_MODULE_ID, &module);
ALOGE_IF(err, "FATAL: can't find the %s module", GRALLOC_HARDWARE_MODULE_ID);
if (err == 0) {
mAllocMod = (gralloc_module_t const *)module;
}
}
#ifdef MTK_MT6589
GraphicBufferMapper::~GraphicBufferMapper() //ERROR IN THIS LINE
{
gralloc_extra_close(mExtraDev);
}

Samsung Galaxy Core Plus (G350 / CS02) CWM & CyanogenMod development

Hey,
I think we have completely stolen the other thread about CWM for our device (SM-G350).
So I started a new one dedicated to development of this phone.
Currently I'm trying to port CyanogenMod 10.1 (4.2.2JB) from Trivalent's source code in GitHub. (Thanks to warlinegtr for finding it)
IF you have any skills that might help with this project, please contact me.
And please don't post links to some basic tutorials, I have already read them.
You can freely post source code that might help us in the future.
Regards, santeri3700

Status 12.9.2015 (DD/MM/YYYY)
Current issue: CM10.1 Cannot boot because of the wrong CWM made for cm_mint. It overwrites init.rc and adds wrong fstab to the system partition.
My own built CWM has graphical bug. Half the screen is black and other half is stretched and pink-ish. Still possible to operate.

[HELP] weird errors with compiling kernel for s3ve3g

So, I decided I want to put Kali-Linux on my samsung s3 neo device, and I succeeded after hard work and a lots of research... Now I had another problem, that my built-in chipset does not support aircrack-ng, so i decided to work around it, and use a wireless usb adapter.
what i did is modifying the kernel, to be able to support some of the wireless devices... the point where i got stuck is at compiling the new-made kernel... basically i followed the following guide:
PHP:
http://forum.xda-developers.com/showthread.php?t=2338179
and i got stuck at the final section of the compiling segment...
So here is my error.
arch/arm/crypto/sha512_neon_glue.c: In function 'sha512_neon_update':
arch/arm/crypto/sha512_neon_glue.c:144:3: warning: implicit declaration of function 'crypto_sha512_update' [-Wimplicit-function-declaration]
error, forbidden warning: sha512_neon_glue.c:144
scripts/Makefile.build:307: recipe for target 'arch/arm/crypto/sha512_neon_glue.o' failed
make[1]: *** [arch/arm/crypto/sha512_neon_glue.o] Error 1
Makefile:950: recipe for target 'arch/arm/crypto' failed
make: *** [arch/arm/crypto] Error 2
Click to expand...
Click to collapse
so, first of all I have a question, where exactly do i put "KCONFIG_CFLAGS += -w" in the code of the Makefile, and if it would solve the error? according to the guide it should ignore errors that the compiler makes.
2nd question right under the code lines.
Makefile:
PHP:
https://github.com/CyanogenMod/android_kernel_samsung_s3ve3g/blob/cm-12.1/Makefile
Couldn't post it here, too long.
Second question, in case the first solution would not work, if i wanted to edit the problematic file, so it would see the declared functions, how do i do that?
NOTE: the error is in line 144

Please help me I will be very thankful.
(NOTE: I am not a developer, and I wish I was, or at least i'm ought to be so please explain carefully your solutions since I'm not familiar with any coding language, and for me, reaching this stage of the kernel compiling was time consuming and my only tools were my logic and the internet). thanks in advance for any help i can get i wish it will work so i can move on in learning kali better!
