I am trying to run hello in spike. It is giving this error:

mada0:~/boom-template/rocket-chip/riscv-tools$riscv64-unknown-elf-gcc -o hello hello.c mada0:~/boom-template/rocket-chip/riscv-tools$spike pk hello ../pk/elf.c:46: assertion failed: !(eh.e_flags & EF_RISCV_RVC)

hello.c

include

int main(void) { printf("Hello!\n"); return 0; } Please help me solve this. Any suggestion will be appreciated.

@palmer-dabbelt I am not sure about the syntax of -march as this is not available so much in online. I tried and gives this error: riscv-tools$riscv64-unknown-elf-gcc -march=rv64gc -mabi=lp64 -o hello11 hello hello: file not recognized: file format not recognized collect2: error: ld returned 1 exit status

Please suggest the syntax.

hello is probably a binary file. A C/C++ compiler works better when you pass a C/C++ file to it. You can use the file command to see what kind of file hello is. Try typing "file hello".

mada0:~/boom-template/rocket-chip/riscv-tools$file hello hello: C source, ASCII text

The compiler assumes that files that end with a .c are C source files, and that files with no ending are linker input files. If you are using a different naming scheme, then you have to tell the compiler that it is a C file. You can use the -x option for that, where language can be c, c++, ada, f77, f95, etc. So try using "riscv64-unknown-elf-gcc -march=rv64gc -mabi=lp64 -o hello11 -x c hello". But the simpler solution is "mv hello hello.c" and then compile hello.c.
