If you want to use the text_64k script, here is a fix:
In the text_64k file (normally installed in /usr/m68k-palmos/lib/text_64k)
you need to add one line to the .bss definition:
Original version:
----------------------------
.bss :
{
bss_start = .;
*(.bss)
*(COMMON)
} > datares
----------------------------
Changed version:
----------------------------
.bss :
{
bss_start = .;
PROVIDE(__text__ = .);
*(.bss)
*(COMMON)
} > datares
----------------------------
That should get rid of your linker error.
I will include this in the next version of my patches.
Thanks (indirectly) for the bug report.
By the way, same change is needed for
/usr/m68k-palmos/lib/text_64k_palmos3
