# reserve initial kernel stack space
.set STACKSIZE, 0x4000 # that is, 16k.
.comm stack, STACKSIZE, 32 # reserve 16k stack on a quadword boundary

gcc says error at end of the line , first unrecogonised character

honestly i know nothing about this, but normally, there are not 2 commas for one instruction, is it possible that the last instruction should only have one?

maybe:

Code: Select all

.comm stack, STACKSIZE 32

or

Code: Select all

.comm stack STACKSIZE, 32

No, the two commas are right for GAS.

Which line generates the error? And are you sure you're compiling this as an Assembly file (.s/.S)?

the second line gives error..

Also remember that the third operand is only recognized when compiling to ELF.

For another executable format, try:

Code: Select all

# reserve initial kernel stack space
.set STACKSIZE, 0x4000 # that is, 16k.
.align 32
.comm stack, STACKSIZE # reserve 16k stack on a quadword boundary

and see if that works.
