The support of yaml-cpp version

[Stars-Collector]

The version0.8.0 of yaml-cpp was realeased last year,but it is not supported by yosys-sta still.And as I do as readme "apt install libyaml-cpp-dev",the 0.8.0 is what I downloaded.Do you have any plan to update the support version?

We have use the yaml-cpp source code in the latest iEDA(https://gitee.com/oscc-project/iEDA/tree/master/src/third_party), so it is not need to install libyaml-cpp-dev.

One temporary workaround is:

• For arch users: ln -s /usr/lib/libyaml-cpp.so.0.8.0 /usr/lib/libyaml-cpp.so.0.7.0
• For debian/ubuntu users: ln -s /usr/lib/x86_64-linux-gnu/libyaml-cpp.so.0.8.0 /usr/lib/x86_64-linux-gnu/libyaml-cpp.so.0.7.0

However, this repo uses an iEDA binary from a downloading script, instead of using a git submodule to compile the source. Someone should write a script to update the binary to https://ysyx.oscc.cc/slides/resources/archive when a new version is commited in gitee source.
BTW, till 2024/12/8, I cloned a clean repo and tried make sta, it still relies on libyaml-cpp.dev.so.0.7.0

Yes, we need update the yosys-sta iEDA binary. However, you can build iEDA by source code from https://gitee.com/oscc-project/iEDA/, and replace the binary in yosys-sta.

I prefer adding a symlink. It's a faster solution and it works well.
