Re: [Gems-users] problem loading ruby module

[Srividya Ramanathan <vidya.education@xxxxxxxxx>]

Thank you very much Dan. Handn't noticed that. The problem went away after installing 64 bit simics.

It looks like you've installed a 32-bit simics workspace:

/home/vidya/Project/gems/simics_workspace/x86-linux/

... but you're trying to load a 64-bit ruby build:

/home/vidya/Project/gems/ruby/amd64-linux/

You should install 64-bit Simics.

Regards,

Dan

Hi all,
I see the following error while trying to load the ruby module:
[vidya@cmpl7 MESI_CMP_directory]$ ./simics -stall -c /home/vidya/aruns_gems/gems_other/checkpoints/first-sarek.check
...
simics> load-module ruby
Error loading module 'ruby': Failed to load module 'ruby' ('/home/vidya/Project/gems/simics_workspace/x86-linux/lib/ruby.so'): "undefined symbol: magic_instruction_callback"

I have built ruby as follows:

cd $GEMS/ruby
make PROTOCOL=MESI_CMP_directory DESTINATION=MESI_CMP_directory

I have set the simics_extra_lib variable
[vidya@cmpl7 lib]$ echo $SIMICS_EXTRA_LIB
./modules

 I also checked that
/home/vidya/Project/gems/ruby/amd64-linux/generated/MESI_CMP_directory/obj/commands.o is present and contains the symbol:
[vidya@cmpl7 obj]$ strings commands.o | grep magic
Unexpected magic call
void magic_instruction_callback(void*, void*, integer_t)

I have also built opal but not any other part of gems. Would you please suggest a solution to the above problem?

Regards
Vidya
