Why "relocation truncated to fit" with this linker script?

Why "relocation truncated to fit" with this linker script?

[Rick Mann]

I get

arm-elf-g++ -Wl,-Map,mapfile.txt -Llib -Xlinker --gc-sections -Xlinker  
--script=link.lds -o h.elf obj/start.o obj/vectors.o src/glue.o src/

Even though my linker script puts start.o and .init & .fini sections  
all together:

SECTIONS
{
	. = 0x00000000;
	
	. = ALIGN(4);
	.text :
	{
		vectorsStart = .;
		KEEP (obj/vectors.o(.text));
		vectorsEnd = .;
	}
	
	. = 0x80008000;

	. = ALIGN(4);
	.text :
	{
		obj/start.o(.text);
		src/Interrupts.o(.text);
	}

	. = ALIGN(4);
	.text : { *(.text) }

	. = ALIGN(4);
	.init :
	{
		KEEP (*(.init))
	} = 0
	
	. = ALIGN(4);
	.fini :
	{
		KEEP (*(.fini))
	} = 0
	


If I remove the . = 0x80008000; line, it works. Obviously, this is not  
all I have to do, but this part should work for now, right?

You have multiple .text output sections.  The linker can't handle
this.

Really? It was handling it just fine before I started trying to use  
memory regions and have chunks of code in vastly distance places.
