hello world not working with spike

[Aylin Hannah]

Hi All,

Please excuse me naivety, this is my first day with riscv software.

I am working on Linux 64 bit. I built spike, pk, gcc tool chain for RV32. When I am able to build executable fine using gcc, but when I run spike I am not getting any output. Absolutely nothing happens.

[pahmad@ibxdv-pahmad ~]$ riscv32-unknown-linux-gnu-gcc -o hello hello.c

[pahmad@ibxdv-pahmad ~]$ spike pk hello

[pahmad@ibxdv-pahmad ~]$ 

Anybody any idea what could be wrong?

Thanks

-Parvez

Parvez, Spike defaults to RV64IMAFD.  Try setting the ISA for your 32bit code.  Look at the Spike help menu.  There is a "--isa" option.  

$RISCV/bin/spike --isa=RV32I pk /path/to/foo.exe

Thanks John,

Here is the output with some of the options I tried. None is clean

Try -static when compiling?
