Unable to run simulator for Hello World demo due to missing files and makefile error

[Aaronyap2002]

hi everyone. As I was following the instructions to run the simulator, when I tried to run the command ./build/lowrisc_ibex_demo_system_0/simverilator/Vibex_demo_system \ --meminit=ram,./sw/c/build/demo/hello_world/demo, it produced the following errors, and I don't know how to fix the issues. My verilator version is 4.210.

I am not sure if this is related, but when I tried to run the make command in the Building Software section for C stack, it produced these errors...

verilated_heavy.h should be located in the standard Verilator include directory. For me this is located close to my verilator binary.
You can find where you Verilator binary is by executing: which verilator
From this path I can remove bin/verilator and add share/verilator/include. There resulting directory contains veraltored_heavy.h.

I'm not exactly sure how you installed Verilator, but I assume something went wrong in the process. I recommend that you follow the "Git quick install" instructions here: https://verilator.org/guide/latest/install.html#git-quick-install

For the software building issue, could you make sure you have riscv32-unknown-elf-objcopy in your path and then use the following patch:

diff --git a/sw/c/gcc_toolchain.cmake b/sw/c/gcc_toolchain.cmake
index d84d1af..00d9e24 100644

How should I run this patch? Just run it in the terminal right?

[rswarbrick]

Marno is suggesting you apply the patch to gcc_toolchain.cmake. There is probably a way to do it with the patch command, but the easiest way would be to manually edit that file to add the line in question.

I've opened up a PR for this: #107

Closing this as it is a duplicate of: #78
