I now know what is going on. I do not know how to fix it... :-)
I have made the changes to the Makefile to add the -Wl,--build-id=none
option to the appropriate places.
I am planning on making a patch file for this to cover all the cases.
This will mean the patch submitted by Ed will not be needed.
The second problem has to do with the .id section and how it is defined
Currently it is as follows:
.section ".id", "a", @progbits
With this in place you cannot place the .id section above the address
0xFFFF_EF00. Doing so will create the error could not allocate in
segment 1. If you use the address 0xFFFF_EF00 or below it will compile
and the text strings vendor and part are in the final binary image at
the address specified.
If you change the id.inc file to :
.section .id or .section ".id"
With this in place you can move the address above 0xFFFF_EF00. The
vendor & part strings are in the crt0.o file and are listed in the
linuxbios.map file. They are NOT in the final binary however.
At this point I am looking for some guidance/help in what to do/look at
next. Do you think this is a ld bug or something else?
Can we live with moving this block below for right now with large
comments as to why?
