Well, at least its working now. I suppose the next time we see this issue we'll suggest a re-install right away.

Hi Philip,

that is exactly what I finally did yesterday. I installed everything from
scratch and it is working now.

Thanks a lot and sorry for all those mails yesterday :)

I've had similar problems in the past, especially when moving around  
files.  The best solution I found was to reinstall gems and ruby from  
scratch.  It's annoying, but often easier than trying to figure out  
why things no longer compile.   A couple weeks ago I had a similar  
error with ruby and opal not compiling, I reinstalled gems multiple  
times, reran the ./configure script in simics etc, and still got the  
same errors.   However with a reinstall of simics and reconfiguring  
the new install things worked fine.   I'd recommend keeping a backup  
of the old simics, as you likely will want to copy over old home  
directories you had in there if you have disk dumps or checkpoints  
saved in that directory.   I will also say that I currently have  
everything running fine on a 32-bit ubuntu dapper system.   Not sure  
if it'll offer any help, but I have installed gcc-3.4 and g++-3.4 and  
have those linked in the makefiles and the simics configure.

One last thing to check is since moving to the new platform, did you  
reinstall the libraries in the simics directories as the gems wiki says?

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.

Dan

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.

I assume then that there are object files in a subdirectory of
$GEMS/ruby/x86-linux?
Try eliminating those symlinks and recompile.

/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

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 ?

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.
