on current http://wiki.osdev.org/Pascal_Bare_Bones, free pascal include RTTI and debug information to binary output kernel. It's useless and the kernel going to big.

I want to make some correction to compiling method.

fpc -Aelf -n -O3 -Op3 -Si -Sc -Sg -Xd -Rintel -Tlinux kernel.pas

it's must be -CX - Create a smartlinked library
-XXs - Create smart link unit and strip all symbols from executable



and

ld -Tlinker.script -o kernel.obj stub.o kernel.o multiboot.o system.o console.o

it's must be --gc-sections - Remove unused sections
-s - strip all symbols


maybe somebody help me to change it. I don't have wiki account.

we have discussed this in http://forum.lazarus.freepascal.org/ind ... l#msg85788

thanks

I think you need to become a member of the "wiki" group here in the forum. Access is free to all forum members and you'll instantly get editing rights for the wiki.

You can give yourself access to edit the wiki. For more info see http://forum.osdev.org/viewtopic.php?f=8&t=677 .

One thing that I did notice in the linked thread is that the change in options do not "fix" anything but cosmetic changes for the poster, it does however introduce a probability that existing code can break for others as it does two things:
- disable RTTI support
- remove debugging information
People might not expect that.
