Thanks for the input Guys👍
I hate people who don’t google first

Anybody has any idea about how to compile a C/C++ source into OS independent executable?
What do you mean like Multi architecture?
Harsh
What do you mean like Multi architecture?
I mean
If gcc can auto compile depending on OS(exe for Win, binary for Linux)
Can't it be OS independent executable?
Just thinking hypothetically

I don’t believe so because Linux and Windows and Mac have different opcodes and so have to be compiled Differently
Dark
Also the file formats are different

Also system calls are different and so on...

I rate Question -1 because could have google that
Dark
Use Java if you want something that runs on Mac, Windows and Linux

I don't think that it is good question to google. Maybe it is better to google "Difference between elf and windows-pe'
Dark
Here comes another

Or just “can you compile a file for Linux, Windows and Mac using C++” would have got the answer

I would say that there should be understanding what's happening under the hood in the first place.

So i was still curious

Compiling is not magic or tho is can seam that why. It converts you readable code to Machine code and Optimises it for the system it’s compiled for

Latter part i probably know from my Android kernel compiling days tho

Try building your own kernel. Now that would be cool but unfortunately I wouldn’t know where to start lol 😂. That’s way above me

They teach this probably in my college (I guess). From basic display drivers

No mate its really uncommon for anyone to learn how to make a kernel
Harsh

I know, but one of my acquaintance did

That's crazy

Because it’s not something most jobs are going to ask you to do.

It's not that hard. Kernel guys maintains good enough docs

Provide info now jk. Tho I would love to see some resources for that

Well again my task was to build a basic kernel that loads the C Standard library and then starts a C program. That’s it
Dark
To me that a success

no worries. but if you will ever want to have some "fun", then "Linux From Scratch" could be nice choice :-)

LFS is about building linux distro, not kernel

Funny huh ? Except kernel is more complex thing that often asked in this chat.
Exactly is a very valid question

That’s a kernel module

Kernels are hard.

Thanks for pointing that out

True.
My irqs dont fire, and it seems my isrs are off aswell. The int instruction always fires interrupt 15, exceptions not caused by int are fine.

Load a C kernel, or load a C program while the kernel is running?
V01D
I am in ring 0.
My kernel cannot du much
V01D
You can check my github in my bio if you like, perhaps you can find the issue.
I gave up, cannot get anywhere and OS development isn't my main thing.
Unless the IRQS somehow work, then I would continue

No user level.
All ring 0

My interrupts and co are in src/cpu/idt
V01D
I will do that eventually.
First I need to initialize all hardware.
V01D
To do that, I need to get IRQ's working
V01D
IRQ's do not fire at all.
V01D
And int instruction returns false interrupt.
The readme shows the bugs

Hi guys
I'm basic level , please help me
How can I get float reminder in devc++?

You mean , We haven't got somekind operation for that
