impl.containerfile tasks

[Unike267]

Intro:

Since f4pga/prjxray#2469, the build of the ghcr.io/Unike267/Containers/impl-arty container has been failing due to the version of Clang installed in the ghcr.io/hdl/impl/icestorm container. The Clang version does not support several features used in a recently added library in the yaml-cpp project (see f4pga/prjxray#2472).

Thanks to the information provided by @SGSSGene, it was discovered that the Clang version in this container is 11, while the newly added dragonbox.h library is only supported starting from Clang version 12 (see jbeder/yaml-cpp#1334).
To address this issue, I added the following code block to the impl.containerfile:

&& apt-get purge -y clang-11 \
&& curl -L -o llvm.sh https://apt.llvm.org/llvm.sh \
&& chmod +x llvm.sh \
&& ./llvm.sh 14 \
&& cd /usr/lib/llvm-14/bin \
&& for f in *; do rm -f /usr/bin/$f; ln -s ../lib/llvm-14/bin/$f /usr/bin/$f; done \
&& clang --version \

However, as discussed this morning with @umarcor, this solution is not elegant and might not work in all cases.

In addition to this, I am starting the container from impl/icestorm, which includes tools that I do not use for synthesizing Xilinx FPGAs. A more logical approach would be to start this container from an image that only has GHDL and Yosys installed.

We also discussed the possibility of generating a new image in https://github.com/hdl/containers, called something like ghcr.io/hdl/nextpnr/xilinx, with an updated version of Clang.

To-Do:

• Regenerate the ghcr.io/Unike267/Containers/impl-arty container starting from an image with an updated GHDL+Yosys version.

OR

• Create a new impl.containerfile starting from ubuntu:latest and install all required tools, including:
  • GHDL
  • GHDL Yosys plugin
  • Yosys
  • nextpnr-xilinx
  • prjxray

I will have to make one of two choices in the next few days.

Cheers!
