Re: [Sdcc-user] (0x300000) is absolute but occurs in more than one file

Hi Kusti,

the error is from changes in gputils. You can downgrade your gputils to
avoid this problem.
I tested successfully with the (ancient ...) version
gplink-0.14.2 #774 (May 30 2013)
and could reproduce your problem with
gplink-1.4.0 #0 (Mar 21 2015)

I then bisected gputils using git and found that r955 from 2014-04-01 is
the last one, for which the old config word approach works.
If I am not mistaken, this should be gputils 1.1.0. So downgrading gputils
to 1.1.0 should solve your problem.

Hope that helps,
Raphael
