Hi All I have been trying to link my assembly code to a C++ file so I can fall my function kMain from assembly and When I link it with this script :
ENTRY(_Start)
SECTIONS
{
. = 0x2000;
.text : AT(ADDR(.text) - 0x2000)
{
_code = .;
*(.text)
*(.rodata*)
. = ALIGN(4096);
}
.data : AT(ADDR(.data) - 0x2000)
{
_data = .;
*(.data)
. = ALIGN(4096);
}
.eh_frame : AT(ADDR(.eh_frame) - 0x2000)
{
_ehframe = .;
*(.eh_frame)
. = ALIGN(4096);
}
.bss : AT(ADDR(.bss) - 0x2000)
{
_bss = .;
*(.bss)
/*
* You usually need to include generated COMMON symbols
* under kernel BSS section or use gcc's -fno-common
*/
*(COMMON)
. = ALIGN(4096);
}
_end = .;
/DISCARD/ :
{
*(.comment)
}
}
I get a warning saying : x86_64-elf-ld: warning: cannot find entry symbol _Start; defaulting to 0000000000002000
But in my Assembly Code I have this at the start:
[BITS 16]
_Start:
Any Ideas as to why its not linking Correctly??
Edit:
I changed it to global _Start:
_Start and it worked my mistake

I hear through the grapevine that the code is here:
https://github.com/AnonymousUser1337/Anmu
Right? Good plan!
Best,
