This issue is due to the spacing between __TEXT and __DATA currently 
being hardcoded in teh variable ${DATA_PAD}. This value needs to be 
calculated at compile time.

For a temporary fix, you can increase the size of DATA_PAD in the 
boot2 Makefile.

Thanks Evan, original value in file i386/boot2/Makefile was DATA_PAD 
= 3582 and it only passes this error with random higher value of 
e.g. 3584 (don't even know what a proper value is) but I still can't 
compile. Produces another error:

Any idea? Thanks again.

Comment 3 by Konstantinos Giannakas, Nov 13, 2012

Hello meklort and chameleon team.
Just updated all files to revision svn2118 and did a clean 
recompilation, but still fails to compile. Any ideas? The trick to 
change the value in ${DATA_PAD} did not work... Still running 10.6.8 
and gcc version 4.2.1 (Apple Inc. build 5666) (dot 3).
Thanks.

Hi, I'm encountering the same problem with rev. 2168 (trunk and 
tags/2.1). Increasing DATA_PAD from its current value of 3582 by 1 
to 3583 generates the same error message. Increasing by 2 or more 
(to anything greater than or equal to 3584) results in

ld: warning: -segaddr __INIT not page aligned, rounding down
ld: warning: -segaddr __TEXT not page aligned, rounding down
ld: image too large: address can't fit in 31-bit r_address field in 
boot2 from /Users/foo/Desktop/Chameleon/trunk/obj/i386/boot2/boot2.o

instead of the previous "ld: segments overlap" error.

Please help, I'm also on up-to-date SnowLeopard (10.6.8) with Xcode 
3.2.6 (1761) (whatever shipped with 10.6 plus most recent software 
updates applied). Same gcc version as original poster.

Thanks !
