I am trying to add a system call to Linux kernel. After executing the command "make -j[nproc]" this error is encountered.
Following are the commands executed:
vim hello/hello.c
in this: SYSCALL_DEFINE1(hello,int, id){...}
Created a Makefile
Added hello/ to kernel/ certs/ mm/ fs/ ipc/ security/ crypto/ block/ hello/ to main Makefile
In include/linux/syscalls.h added- asmlinkage long sys_hello(int id);
In arch/x86/entry/syscalls/syscall_64.tbl added- 442 common hello sys_hello
make menuconfig
In make -j2 I am getting above error

I'm trying to follow this guide as my entry into Solana blockchain development. I'm running into an error when I run the command $anchor build
For context, I'm running wsl. I'm not concerned about the warning, but any help would be much appreciated!
Here are the contents of the error:
error: linking with `ld` failed: exit status: 1

It looks like the build is not using the correct linker that's part of the BPF tool suite, probably using the default ld instead.
Can you make sure that ~/.local/share/solana/install/active_release/bin is part of your PATH? After that, try simply running cargo build-bpf to make sure that the program can build without Anchor. If it's still failing, you may need to reinstall the Solana tools.
I fail to compile sources of GoodbyeDPI v0.1.6 project https://github.com/ValdikSS/GoodbyeDPI/releases/tag/0.1.6.
When I run the command
make CPREFIX=x86_64-w64-mingw32- BIT64=1 WINDIVERTHEADERS="C:\Users\Admin\Downloads\WinDivert-2.2.0-Source\WinDivert-2.2.0\include" WINDIVERTLIBS="C:\Users\Admin\Downloads\WinDivert-2.2.0-A\WinDivert-2.2.0-A\x64"
which uses dependency on WinDivert project https://reqrypt.org/windivert.html I get the following output:
x86_64-w64-mingw32-windres goodbyedpi-rc.rc goodbyedpi-rc.o
process_begin: CreateProcess<NULL, x86_64-w64-mingw32-windres goodbyedpi-rc.rc goodbyedpi-rc.o, ...> failed.
make <e-2>: Can't find the file specified.
make: *** [manifest] Error 2
although I write the make command as it's said in Readme (at least I think so). I'm not very experienced in make procedure, so help me to figure out the problem, please.
I am able to follow the directions on the dpdk docs for windows.

I am able to run meson build and ninja -C build and everything seems to work. The problem is whenever I run with the flag -Dexamples=helloworld, or any example for that matter, I get the following failure after running ninja -C build

I have a similar problem to this one, only for me it's an error not a warning. I'm building linux-4.8.5 with a patch applied to one module. I get:
ERROR: "intel_soc_pmic_readb" [drivers/gpu/drm/i915/i915.ko] undefined!
ERROR: "intel_soc_pmic_writeb" [drivers/gpu/drm/i915/i915.ko] undefined!
scripts/Makefile.modpost:91: recipe for target '__modpost' failed
make[1]: *** [__modpost] Error 1
Makefile:1201: recipe for target 'modules' failed
make: *** [modules] Error 2
In the other question they say something about KBUILD_EXTRA_SYMBOLS and documentation is supposed to be in Documentation/kbuild/modules.txt. But reading this file, this seems only to apply to modules not included in linux itself?
The functions are defined like
int function(){
do_stuff;
}
EXPORT_SYMBOL(function);
then there is the declaration
int function();
in a .h file in the include folder and it's called like
#include <the_aforementioned_file.h>
//stuff
function();
from a file in the same folder as the definition of the function. There are no other occurrences of the function name in the whole source tree.
And I really just don't see the mistake. Most likely I'm not looking in the right place, I guess.
As explained in a comment by Tsyvarev, this error is caused because the module in question is not being built, it requires the option CONFIG_INTEL_SOC_PMIC.
I am getting following error when i try to insert a module
insmod: error inserting 'memory.ko': -1 Unknown symbol in module
Following happens when i make the module
make -C /lib/modules/2.6.32-279.19.1.el6.x86_64/build SUBDIRS=/work modules
make[1]: Entering directory `/usr/src/kernels/2.6.32-279.19.1.el6.x86_64'

make[1]: Leaving directory `/usr/src/kernels/2.6.32-279.19.1.el6.x86_64'
You can see the reason of the error is arch_vma_name
Here is chunk of code where i used it
const char *name = arch_vma_name(vma);
I have included the header file
#include <linux/mm.h>
I am not able to understand the reason.
