Re: [ECOS] synth linux tests: address 0x0 of cache section .fixup is not within region rom

I haven't solved your problem but I think I've isolated it.

I'm having the same problem when creating the tests (or any program) for a
Linux synthetic target.  I've loaded the current (as of mid-March) CVS ecos
and configtool. I relooked at the ecos build and I have an error (just an
error statement in the output stream with the build continuing as if
everything's ok).  The error encountered is that the build process
(makefile) couldn't find the init.tcl file and comes up with the error
message that TCL may not have been installed correctly.  This error occurs
after the heaps.cxx file is made. The build is looking for a TCL8.0
directory under the tools/share, tools/H-i686-pc-linux-gnu/usr/share or
tools/H-i686-pc-linux-gnu/share directories.  I added to the search path the
TCL installed at usr/lib/tcl8.3 but get the same error.  My next step is to
install TCL under one of the above listed directories (probably tools/share)
but am not real confident since the makefile seems to be looking for a
static tcl8.0 directory name where the init.tcl file is located. I just
haven't had the chance to try that or trace the makefile command path to
find the location where the TCL directory is defined  (I'm working on
porting a program to ecos under the linux synthetic target and i386 target,
part-time). Since the error occurs where the heap is defined I believe
that's why the gnu linker can't find the specified memory regions for the
Linux synthetic target and errors on a cache overlap.

The following is my build error listing:

This probably means that Tcl wasn't installed properly.



Hope this helps.  If you solve it before me, please let me know what
corrected the problem.

Thanks
