Hey guys, I am trying to port Ubuntu Touch for my i9100G. All was going well but this error occurred when compiling. It seems there's a problem about mmu.c. I ve searched about it but no luck. Need your help!
Note: I opened the thread here and not Ubuntu Touch section because I think the problem is about compiling CM 10.1 kernel, not about porting Ubuntu.

Hope this is the correct forum for this, tried under the HTC One X evita Q/A forum but was told it fits better here.
Hey all, so I've built out a development environment and have followed tutorials on how to build CM10.2 from source. I would consider myself an advanced Linux user and things have been going well with the exception of these compliation errors. Any help troubleshooting these would be greatly appreciated.

I'm using ndk gcc 4.8. This error is present also on gcc 4.7. The only way to get rid of this error is to use toolchain 4.6. I need to compile it using a newer toolchain, that's why I request your help.
Any ideas?

I guess you are looking on another file.
Code:
error, forbidden warning: dynamic_debug.h:75
I guess there is a problem in dynamic_debug.h in line 75. I guess you need to initialise something.
Here is dynamic_debug.h but I can't find the problem.
I will appreciate any opinion.
Try this method!

I am not much used to kernel related development but I analysed your dynamic_debug.h and found the problem (maybe a problem):
Normally, a do-while loop syntax is this:
Code:
do
{
Statement1;
Statement2;
...
}while(condition);
But I don't see a semicolon in the end of those loops in your code. This maybe a syntax error.
Also analyse these codes:
Code:
#if defined(CONFIG_DYNAMIC_DEBUG)
extern int ddebug_remove_module(const char *mod_name);
extern __printf(2, 3)
int __dynamic_pr_debug(struct _ddebug *descriptor, const char *fmt, ...);
struct device;
extern __printf(3, 4)
int __dynamic_dev_dbg(struct _ddebug *descriptor, const struct device *dev,
const char *fmt, ...);
struct net_device;
extern __printf(3, 4)
int __dynamic_netdev_dbg(struct _ddebug *descriptor,
const struct net_device *dev,
const char *fmt, ...);
Every intialisation has 4 protocols but the first initialisation contain only 3.
Try the above things and tell me back if it works or not.
So, the problem was in Makefile and .config. I compared and added some flags from Mako (from franco) and it worked. I still have some warning/s, some breakpoints but at least now it's working. Anyway, this thread may be useful for all of us. Thanks a lot for help.
Now, another problem.
Code:
CC fs/proc/loadavg.o
CC fs/proc/meminfo.o
fs/proc/meminfo.c: In function ‘meminfo_proc_show’:
fs/proc/meminfo.c:175:1: internal compiler error: in optimize_sc, at modulo-sched.c:1069
}
^
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://bugs.launchpad.net/gcc-linaro> for instructions.
make[2]: *** [fs/proc/meminfo.o] Error 1
make[1]: *** [fs/proc] Error 2
make: *** [fs] Error 2
[email protected]:~/kernel2$
With linaro 4.8.3 => OK;
linaro 4.8.3 + A15 optimize=> fail, error above. meminfo.c it's exactly like the one from nexus 4.
FIX: compiler bug;

Hey sarsdani Apologies that I'm quoting you 12 month later. I am getting an identical error in the same file/address as you had when you posted this question. Im compiling stock HTC m7 Android L kernel with Google tool chain 4.8 - android 5.1 r1
You mentioned later on that you changed the Makefile and .config to fix the [-Wmaybe-uninitialized] error. Can you please detail what those changes were or point me to an example ( if you can remember ) I could just change Wmaybe in Makefile to Wno but turning the flag off altogether seems dangerous.
@Joeisgood99 there are two ways to solve this.
1. using a "hack". So, you need to add in makefile (in root folder from kernel source) at KBUILD_CFLAGS: -Wno-maybe-uninitialized \
2. Open that file with the error and asign a value to protocol.
The first option is not dangerous. Why? Because only the toolchain say this. In gcc 4.6, the reason why you don't get this error is because it assign a value automatically to that "protocol", usualy random value but not always. In gcc 4.7/4.8/4.9(or 4.10) this is threated as warning/error.

Any ideas what this could be? I'm a bit stumped i've never seen an error like this before
It's okay i retired the project as of now since trying to modify the kernel source code isn't do anything but causing more errors. I do appreciate any help when everyone has a chance
So I've done some work on boot images before, but not much, and I wanted to try building a kernel for AOSP KitKat on the EVO 4G LTE. (Why not Lollipop? Data and roaming issues.) But I'm hitting camera-related errors when I try to compile it. Here's the relevant output in the make process:
Code:

make: *** [arch/arm/mach-msm] Error 2
I tried to fix it by adding the HTC_CAMERA_HAL_VERSION config to Kconfig, but then I get this error instead:

Hi everyone I have been wanting to try to compile the kernel for my device from source so that I can add some features to it. first time trying this..
I have fixed all errors up till now but this one has been bothering for a few days:
Code:

thanks guys, i'm really at my wits ends right now
