/home/nikolas/gems is a link to /media/gems
so this shouldn't affect anything. I am beginning to think that since Ubuntu
does a minimal installation by default, I am missing a library or something
similar. Unfortunately the error message isn't helping.
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 ?

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
$GEMS/common/Makefile.common, around line 46:

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

Hello again,
I had to format my PC and I changed my linux distribution to Ubuntu. I am
trying
to setup GEMS again but I am having some problems that I haven't
been
able
to
solve. From what I understand something goes wrong during the
linking
process.
I am using gcc 3.3, Simics 2.2.17 and GEMS 1.2
The output I am getting from the 2 modules is:

I have tried recopying my library files, cleaning up previous makes etc.
to
no
avail. Any suggestions?
Thanks in advance,
