I’m attempting to package Vivado 2022.2. I believe I’ve gotten pretty far in the process, but I’m running an issue. When I run the vivado binary (`./result/opt/vivado/Vivado/2022.2/bin/vivado`), I see the error `unexpected PLT reloc type 0x00`. From a quick search, this appears to be an issue with the linker tables.
The current build expression for this is:
```auto

Any ideas about what might be going wrong here? Or, at least, any hints about the right direction to proceed?

No idea, about what is going on, but usually read ldd output for that binary helps debug linker tables
```auto
ldd ./result/opt/vivado/Vivado/2022.2/bin/vivado
```
Check if pointed libraries exists

Thanks for the note. Yeah, I tried this - they’re all there. FYI `bin/vivado` is a shell script that invokes `bin/unwrapped/lnx64.o/vivado`, hence why I’ve used `ldd` on the latter.

You could try `LD_DEBUG=reloc` or `LD_DEBUG=all` to debug relocation processing & combine with `readelf` to investigate further.
But Vivado is extremely huge/complicated - this is going to be a long ride. I do hope you’re aware of that and have already seen [Fhs env for installing xilinx - #2 by Mic92](https://discourse.nixos.org/t/fhs-env-for-installing-xilinx/13150/2) for hints on getting it to ‘just work’ in a _FHSEnv_.

I was not aware of FHSEnv - thanks for pointing that out. I’d eventually like a proper build expression for the Xilinx tools, but that seems like a good intermediate solution.
