I have a C code that takes value form two input file calculate multiplication
and write the time into another text file. First I compile and make executable
with GCC and the name is Method1_X86_BINARY_
> gcc DecMulTimeMeasure.c decContext.c decDouble.c decQuad.c -o
> Method1_X86_BINARY_
The executable is working ./Method1_X86_BINARY_ file!
Now I want to compile using gem5 SE mode by bellow command
./build/X86/gem5.opt configs/example/se.py -c
tests/test-progs/hello/bin/x86/linux/Method1_X86_BINARY_
After that I receive following error
> GEM5 SIMULATION START problem reading inputA.txt file Exiting @ tick 9053500
> because exiting with last active thread context
Simulated exit code not 0! Exit code is 1
The Message ***GEM5 SIMULATION START*** and ***problem reading inputA.txt
file*** shows form my C code where bellow :
FILE *ptr_file_read, *ptr_file_readB,*ptr_file_write , *Mptr_file_write;
char fileNameA [40] = "final_result_a.txt";
char fileNameB [40] = "final_result_b.txt";
printf("GEM5 SIMULATION START");
ptr_file_read = fopen(fileNameA, "r"); //Name of the input file
if (!ptr_file_read)
{
printf("problem reading inputA.txt file");
return 1;
}
So the message ***GEM5 SIMULATION START*** indicate that the executable is okay
where as the message ***problem reading inputA.txt file*** indicates the
problem is during reading form text file.
My question is how I can run the file in GEM-5 simulator.
