I am building Linux Image using Yoctobuild system on Ubuntu 18.04 host machine. I am following steps provided over here. I am building for Colibri iMX6ULL computer-on-module. However, my build has failed and it is showing errors given below

Can someone help me? I can't switch to ubuntu 16.04 but I think it should be working with my system as well.
This is a known issue at Toradex and is on the Roadmap, see issue #36657.
Fixes are already in the upstream layers, and we have updated our BSP repo. You can try this branch by using the LinuxImageV2.7-integration branch.

The command I'm running is make. Can anyone explain to me what I'm doing wrong?
The _ASM_EXTABLE_HANDLE macro is replaced by _ASM_EXTABLE_TYPE in the newest kernel versions.
Say I have main.c:
#include <linux/list.h>
int main() {}
uname -r resolves to the 5.13.0-28-generic and I run Ubuntu 20.04 x86_64.
See what happens:
username#username-laptop:~$ gcc -o main -I/usr/src/linux-headers-$(uname -r)/include main.c

OK. Seems asm/linkage.h is platform-specific so I can't get if from the -generic headers. sudo find / -name linkage.h | grep x86 suggests the /usr/src/linux-hwe-5.13-headers-5.13.0-28/arch/x86/include include. So let's add that one too:
username#username-laptop:~$ gcc -o main -I/usr/src/linux-headers-$(uname -r)/include -I/usr/src/linux-hwe-5.13-headers-5.13.0-28/arch/x86/include main.c

Have no idea what is wrong with my configuration. Any ideas?
maybe this question is stupid but i really am not able to get a way to fix this i am trying to make a file in Cygwin64 i have all the dependency files installed, but when i make the file it throws me this

Your problem is that you've added the -ansi option to your compile line:
x86_64-w64-mingw32-gcc -D OS_WINDOWS_NT -ansi ...
The -ansi option tells the compiler to compile your code as if it were ANSI C 89 standard code. That version of the standard did not support the // single-line comment delimiter: it only supports the traditional /* ... */ comments.
However the header file you're including clearly expects to be able to use // comments. So you cannot use the -ansi flag when you compile with these header files.
I'm upgrading from Redis 6.0.13 to 6.2.5 on AIX.
On 6.2.5, the build fails with this error:

I checked the eventLoop struct, and it does indeed contain events, but I see the build failing because it's trying to access reqevents. I can't find reqevents anywhere in the project (with grep -R 'reqevents' .)
This error only happens on AIX 7.1 - Linux and macOS both work fine.
Do you know why req would be prepended to the struct members on AIX, and how I might solve the error?
I planned to use the SoLoud library (https://sol.gfxile.net/soloud/index.html) for my C project. I can't understand how to compile the C demo file contained in
/demos/c_test/
to make it executable.
Can someone help me to understand how to compile it using gcc?
in the demos/c_test/main.c,
I changed:
#include "soloud_c.h"
to
#include "../../include/soloud_c.h"
and it compiled. However, the compiler output the following warnings:
gcc -ggdb3 -Wall -Wextra -Wconversion -pedantic -std=gnu11 -c "main.c" -o "main.o" main.c:

Compilation finished successfully.
Note: I did not bother to link the executable, however, I did note a few items of interest.
the available libraries are *.dll files, so this is expecting to be compiled/linked under the windows OS.
under the 'bin' directory are the libraries: soloud_x64.dll, soloud_x86.dll and SDL2.dll. I don't know which of these libraries your specific computer will need to include
