i386:x86-64 architecture of input file `kernel.o' is error

[Mehmetdev1]

i386:x86-64 architecture of input file `kernel.o' is incompatible with i386 output It gives the error, what is the solution, I will post the screenshot and the c++ code.

Code: Select all

void printf(char* str)
{

    unsigned short* VideoMemory = (unsigned short*)0xb8000;

    for(int i = 0; str[i] != '\0'; ++i)
    VideoMemory[i] = (VideoMemory[i] & 0xFF00) | str[i];

}


void kernelMain(void* multiboot_structure, unsigned int magicnumber)
{
    printf("Kapiler İsletim Sistemi");

    while(1);

}

Seems pretty self-explanatory.

You are trying to link a 64-bit object file into a 32-bit executable. Not possible.

Presumably you compiled your source with a 64-bit compiler. You either need to tell it to produce 32-bit code or (much better) use a 32-bit cross compiler.

X32 I am using a compiler.

You are using a 64-bit compiler (or assembler) to produce kernel.o.

X32

Are you talking about the x32 ABI? That's still 64-bit. You need 32-bit.

Ideally, you should use a cross-compiler. I would also suggest working on some easier projects first so you can learn the basics.

I feel like this is becoming a trend -- people think that you can just use a hosted compiler to build an OS. I'm kinda curious why people repeatedly assume this, particularly since it causes so, so many problems and is so painful.

[Octocontrabass]

It's because of all the tutorials that use a hosted compiler.

This code is also from a tutorial. I'm not sure which one, but based on the typos, I'd guess a video.
