After a clean install of xc7 tools according to the symbiflow-examples instructions, I get to the first example to run (https://symbiflow-examples.readthedocs.io/en/latest/building-examples.html):

TARGET="arty_35" make -C counter_test

and this runs Symbiflow but ends with this error:

The ANTLR parser has some dependencies outside of PyPI, which is why the fallback parser is necessary.

Could you please post the results of:

sudo apt install cmake default-jre-headless uuid-dev

cd fasm
make build

Thanks.

You'll definitely need cmake. Once you have a working cmake, pip install -v git+https://github.com/SymbiFlow/fasm.git should install the Cython requirement automatically.

You'll definitely need cmake.

I do have cmake -- as a Python module.

$ which cmake
/home/tim/.local/bin/cmake
$ pip list | grep cmake
cmake                  3.16.3
$ pip3 list | grep cmake
cmake                  3.16.3

In other instructions that asked me to sudo apt install cmake <other packages>, I'd just skip the cmake and it would be ok.

But, let me get to the bottom of why the apt install of cmake doesn't work for me.

@andrewb1999 I can see that cmake failed, but unfortunately not why. This should print the output from cmake:

python setup.py won't install dependencies, all dependencies must be preinstalled. You probably want something like pip install . if you want packages to be installed.

My problems installing cmake with apt seem to have originated from having "kitware" as a source. After I removed that, I was able to install cmake. I'll try the install again and see if it goes any better.

tcal-x commented Dec 21, 2020

I ran this to take care of the Cython requirement:

pip3 install cython

Then I followed the instructions on the page https://github.com/symbiflow/fasm#build-instructions including the sudo apt install ... libantlr4-runtime-dev and the git submodule update --init, and after that, the make build succeeded. I did this install (also from the page mentioned earlier) while still in the conda environment ("xc7"):

pip install . --install-option="--antlr-runtime=shared" --no-use-pep517

and then the original SymbiFlow build of the counter example worked.

It looks like the install instructions specify an older version of the toolchain. Should this be automatically updated somehow? There are "latest" text files that specify the latest URL: https://github.com/litex-hub/litex-conda-eda/blob/master/pnr/vtr-optimized/build.sh#L34-L53

Correction: the final warning from fasm looks like failure, but in fact a bitstream is produced, and it works correctly on the Arty 35T board (counter_test example).

I had noticed in Quicklogic guides for QORC, they specifically describe this warning and tell the user that it's ok.

This is the warning:

I was also running into this. Although there is a fallback, the warning would be printed to my fasm file, which would then break things:

I followed @HackerFoo 's instructions and did the following:

git clone https://github.com/SymbiFlow/fasm.git

make build

After which I realized I needed to:

  1. Make python point to python3. (I'm using Ubuntu 20 where python points to nothing by default. I just added alias python=python3 to my ~/.bashrc).
  2. sudo apt install python3-venv

This fixed thing for me and the fasm.parser ImportError is gone. Hope this helps others.

Couple things. First, we have an PyPi account setup, so if someone adds a PyPi publish to https://github.com/symbiflow/fasm, this issue becomes must easier to solve!

Second, there are instructions in https://github.com/SymbiFlow/fasm/blob/master/README.md on how to build FASM with the ANTLR parser.
