[Gems-users] Physical memory read raised exception

["Liu, Mingliang" <mingliang.liu@xxxxxxxxx>]

Hi guys,

 

I build my ruby and opal under gcc-4.2 and it seems that the ruby module works fine. I builded opal with some efforts including copying some functions from cache.C to cache.h and modifying Makefile.

When I load opal module and init it, I meet some warnings. Then errors occurred when I tried to start the opal module as following.

 

I have searched the user list to find that there is no solution to this question, although it occurred several times. I am a newbie to GEMS and any hints or help is heavily welcomed.

p.s. My machine is amd64-linux and the solaris10 operating system is booted under GEMS 2.1.1 (the newest version by now).

 

Regards.
