[gem5-users] Re: How to redirect the fopen to open a different file instead of specifed filename in the program binary given as input to gem5 simulator in SE mode

Hi gogineni,

You will have to modify the hello world program to take in a command line 
argument and use that instead of hard coded file name. Something like this

 fp = fopen( argv[1] , "w" );

In gem5, if your se.py equivalent system is using the default set of command 
line parameters defined in config/common/Options.py, you can use --options 
parameter to pass options to hello world program. Something like this

build/X86/gem5.opt config/examples/se.py -c hello.exe --options hello.txt
