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

[Carles Hernández <carherlu@xxxxxxxxxx>]

Dan,
The function init_local() isn't reached. The problem seems to be in 
$SIMICS_INSTALL/config/module.mk when it tries to sign the module that 
has just been  compiled.  So, the problem is that the compiled module is 
rejected when simics tries to sign it, and the make process removes the 
module.
Anyway could be helpfull for me to know some working configuration of 
Simics 3.0 with gems, that is: OS, gcc version, simics subversion and 
gems version.
Thank you
