Re: [Gems-users] Problems with -sign-module

[Dan Gibson <degibson@xxxxxxxx>]

Ok, lets try a different approach.

If Simics is crashing when loading Ruby for module signing, then we should verify that ruby/module/ruby.c is executing the correct code at load-time.

Have a look at ruby/module/ruby.c, at about lines 268-293. These lines in Gems 1.3.1 are intended to catch case where Simics loads Ruby for "signing". However, if for whatever reason  SIMICS_3_0 isn't #define'd, then problems could arise.

To debug your problem, try the following:
 * Add the following right after the #include's, (approx line 76). This will "permanently" convert your ruby/module/ruby.c to Simics 3.0.

#ifndef SIMICS_3_0
#define SIMICS_3_0
#endif

 * If that doesn't work,  populate the init_local() function with printf() calls every few lines to try to determine where the error occurs.

    Dan,
    I have set the GEMS_ROOT variable to $(SRC_BASE). I've compiled ruby 
and simics many times, but always appears the same error (Error 2) after 
building ruby. I've succesfully installed Gems with simics 2.0.X, but I 
need to use simics 3. 

Thank you for your help.

  

Carles,
  
I looked into things, and made a mistake in answering your question. 
There is no longer an explicit SIMICS_VERSION flag in the module 
makefiles of Gems 1.3. There *IS*, however, a path that must be set 
appropriately for Simics 3.0, which specifies the Makefile's GEMS_ROOT 
variable. Can you please verify that your ruby/module/Makefile has 
GEMS_ROOT set to $(SRC_BASE)/../../ ?
(then make clean and build again)

Regards,
Dan

    I think this changed in GEMS 1.4 ... I could be wrong. When I
    initially ported GEMS to Simics 3, my port had a flag in
    ruby/module/Makefile -- that may have disappeared.

        I'm pretty sure that the only place that SIMICS_VERSION needs to be
        set is in

          common/Makefile.simics_version

        (This is different from what Carles said that he did.)

            As I recall, there is another flag that must be set in ruby/module/Makefile.

                Thank you Dan for your answer.
                I have set the SIMICS_VERSION flag to 3.0 in $GEMS/common/Makefile.common.
                Did you mean this flag?
