| umarcor|2 | mithro, CarlosEDP, if you mean the ghdl-yosys-plugin, there are two different approaches. | 00:38 |
|---|---|---|
| umarcor|2 | on windows (MSYS2) the plugin is built into yosys, because yosys does not support dynamically loading modules on windows (yet) | 00:38 |
| umarcor|2 | on linux (containers) the plugin is built as a shared library (module) and shipped "independently". | 00:39 |
| umarcor|2 | however, the plugin does always depend on a working GHDL installation. no matter if it's built-in or a module. | 00:39 |
| umarcor|2 | that's because the plugin using libghdl, which uses the standard and IEEE libraries in the GHDL installation. | 00:40 |
| umarcor|2 | so, the plugin does not use the GHDL binary, but it uses almost all the rest of the content of an installation. | 00:40 |
| umarcor|2 | that's why GHDL is a dependency of Yosys on MSYS2 | 00:40 |

| sf-slack | <acomodi> mithro: yep, should be setup here: https://github.com/SymbiFlow/fpga-interchange-tests | 16:09 |
| mithro | @acomodi If you don't keep poking me it will never happen :-) | 16:09 |
| sf-slack | <acomodi> yeah, I guess I'll increase the poking frequency then :) | 16:11 |
| sf-slack | <acomodi> There is a PR that adds a basic kokoro configuration here: https://github.com/SymbiFlow/fpga-interchange-tests/pull/4 | 16:12 |
| mithro | We only need ubuntu testing right? | 16:13 |
| sf-slack | <acomodi> Yeah, I think it is enough | 16:14 |
| sf-slack | <acomodi> Probably we can have other OSes and distros testing setup with GH actions instead | 16:14 |

| jhu | Hi guys, I previously asked this question in #litex but they told me to come to you guys. I don't really understand what the error means when I'm trying to create the bitstream with the symbiflow toolchain. Is there something wrong with how i configured the installation of symbiflow? | 17:06 |
| *** sf-slack1 has joined #symbiflow | 17:42 | |
| sf-slack1 | <acomodi> jhu: It might be that there is something wrong with the XDC, or indeed the symbiflow setup. I suggest to open an issue in symbiflow-examples (https://github.com/SymbiFlow/symbiflow-examples) with a description of the error and the steps required to reproduce it | 17:42 |

| jhu | Do you have any suggestions on how i could fix this problem? I will post an issue on there as well. | 17:56 |
