Error during 'sim.py' execution #98

Closed natanvotre closed 4 years ago

natanvotre commented 4 years ago

I am getting this error when I am trying to run ./sim.py:

I think that riscv-gcc is not compiling properly, but I am a benniger on this platform and I couldn't solve.

Does someone can help me? I tried to run using Ubuntu 18.04, docker and also a gcloud instace Debian 9

enjoy-digital commented 4 years ago

it seems LiteX was not installed correctly and that compiler_rt submodule is missing. Can you tell us more how you installed LiteX? have you followed https://github.com/litex-hub/linux-on-litex-vexriscv#installing-litex to install LiteX? Can you check if compier_rt submodule has been correctly downloaded in litex/soc/software/compiler_rt?

natanvotre commented 4 years ago

Yes, I followed these steps:

$ wget https://raw.githubusercontent.com/enjoy-digital/litex/master/litex_setup.py
$ chmod +x litex_setup.py
$ ./litex_setup.py init
$ sudo ./litex_setup.py install

During the ./litex_setup.py install I got this report from Litex installation.

But, you are right. The folder compiler_rt is empty.

natanvotre commented 4 years ago

I saw that compiler_rt was a submodule folder and something removed all the files inside.

I restored all the compiler_rt, installed litex again and I ran .sim.py again.

Now I got this error running manually make -C /home/natan/Documents/Brickabode/FpgaResearch/riscV/spinalHDL/linux-on-litex-vexriscv/build/sim/software/libcompiler_rt -f /home/natan/Documents/Brickabode/FpgaResearch/riscV/spinalHDL/litex/litex/litex/soc/software/libcompiler_rt/Makefile:

Do you have some hint why this is happening @enjoy-digital ?

enjoy-digital commented 4 years ago

@natanvotre: i don't understand why compiler_rt was initially removed or empty. Can you try removing all repositories and doing a fresh install? If compiler_rt is still empty, can you post your install log?

@enjoy-digital , I see, that was my mistake. For some reason I cleaned this repo with some command.. Anyway, I tried today with my other computer and I got this error

and when I ran into the command line:

After that, when I tried to mv the litex files and installed it again, the same error as the first comment appeared. (probably was that my first error, I moved and accidentally removed somethings and got to this error.) After that, when I checkout to origin/master (commit 69445f095) appeared this same error.

@enjoy-digital I solved the problem.. I have created a Dockerfile in order to set-up a machine for this repo, and it worked.

Probably the error was that I was using python3.6 and with some outdated libraries. I need to confirm that, please don't close the issue yet.

enjoy-digital commented 4 years ago

@natanvotre: have you been able to check what caused the issue?

freddy- commented 4 years ago

I've had the same problem. The submodule compiler_rt was empty. At first i thought that the submodule URL was offline or something, then I manually changed to https://github.com/llvm-mirror/compiler-rt.git and runned the command: git submodule update --init --recursive After that the SoC build worked. Later I find that the original submodule URL was working correctly, I think it just doesn't open in the browser...

natanvotre commented 4 years ago

@natanvotre: have you been able to check what caused the issue?

It seems that it was just matter of environment. With the docker, I could run either in pyhton3.6 or python3.7, That seemed to be the problem.

Anyway, thanks for helping me with this Issue and, either way, now we have a Dockerfile that can be used as reference!
