Unable to build the plugin

[canerbulduk]

While building the plugin via "make", I was getting the following error.

src/ghdl.cc:760:8: error: use of undeclared identifier 'Id_Dlatch'; did you mean 'Id_Latch'?
                case Id_Dlatch:

Yosys 0.22 (git sha1 f109fa3d4, gcc 9.4.0-1ubuntu1~20.04.1 -fPIC -Os)

As a solution, I reverted this, 90c5411 , commit on my end, the result was a success.

Get the latest checkout of ghdl or get an older version of the plugin.

If there was a tag that shows which version of ghdl-yosys-plugin is compatible with ghdl 2.0 that would be most useful.

The release date of ghdl 3.0.0 is march 8th 2023, your commit was already on july 14th 2022.

In my case I am working on a Debian 12 system.
The version of ghdl that comes with Debian 12 is 2.0 but no versions of ghdl-yosys-plugin support Id_Latch.
Hopefully maintainers of Debian will catch up with ghdl 3.0 soon. That will alleviate these issues.

[tgingold]

This is a tricky issue as the plugin is between ghdl and yosys. So ideally you'd like a tag for each release of ghdl and yosys... Hopefully, there aren't many commits in the plugin and the interface is quite stable.

I know this is an old issue, but I just spent a good hour with a similar problem, that was solved by checking out an older version. GHDL version Debian 5.0.1, compiles up to 8c29f2c, but not further.

Error was:

In case someone wants to google it and have an idea of what's going on.

Since one can put multiple tags on a single commit, one could set a separate tag for yosys and ghdl. That's standard in many development cycles as well.

Thanks a lot, you just spared me wasting lots of time!
