The problem seems to be due to *where* the build process is looking for
the object files:
/home/nikolas/gems/programs/sparc/simics/../ruby/x86-linux/generated//obj/
Notice the double /. It *should* be looking in
x86-linux/generated/[PROTOCOL]/obj, but obviously the protocol string
appears to be blank. I don't think this is an Ubuntu problem or a gcc
problem, but something going wrong somewhere in the Makefiles.
Are you properly defining the PROTOCOL Makefile variable on the command
line?
The path above is specified by ruby's module makefile, in
gems/ruby/module/Makefile. Can you verify that the paths are correctly
set for Simics 2.2.17 in that file? It would seem that, somehow, the
definition of PROTOCOL is not surviving to reach that makefile.

I did eliminate the symlinks. No change noticed.
The obj directory exists in MOSI_SMP_bcast directory and is full of object files
while the make is happening, but it is being removed at the end of the process.
Quoting Dan Gibson <degibson@xxxxxxxx>:
I assume then that there are object files in a subdirectory of
$GEMS/ruby/x86-linux?
Try eliminating those symlinks and recompile.

No, I doubt that. The symbol it is having problems linking with is
defined in $GEMS/common/util
The issue here is that Ruby/Opal Makefiles will build the object files.
Then to build a Simics module, we use the Virtutech Makefile which may be
using a different compiler. The compilers do not seem to agree on the
names of mangled symbols.
This problem comes up frequently on the list. We currently do not have a
clear, bullet-proof solution.

A path seems to be inconsistent:
/home/nikolas/gems/programs/sparc in one message
/media/gems/programs/sparc/ in another...
This is probably an artifact of the reformat you mentioned -- did you
copy files directly from one install to the other by chance? Otherwise,
grep for whichever path is wrong, and change it.

The "make ruby" command from
$GEMS/simics/x86-linux/lib
fails with the same error message:

ls:

I have tried both with
SIMICS_VERSION := -DSIMICS_2_2
and
SIMICS_VERSION += -DSIMICS_2_2
Could this be a compatibility problem with gcc-3.3 ?
Nikolas
Quoting Dan Gibson <degibson@xxxxxxxx>:
The latest version of GEMS handles Simics versions a little
differently, by changing Makefile.simics_version. Don't use the append
operator in Makefile.simics_version in GEMS 1.2+... that could break
several #ifdefs in various places. Use := instead of += if you're
defining the Simics version.

Check that you have the correct simics version in

Good luck,

I am using
./configure CC=/usr/lib/gcc-3.3
and I am using g++-3.3 in the GEMS Makefiles

Have your run the Simics configure step?
cd $GEMS/simics/x86-linux
../configure

I am using gcc 3.3, Simics 2.2.17 and GEMS 1.2
The output I am getting from the 2 modules is:

no
