Hello! I encountered build errors when compiling OpenCOPTER with ldc2 on my WSL Ubuntu2004 setup. The errors involve failed type casting between double[] and double, and issues with template instantiations, notably with sqrt!(immutable(double[8])) and atan!(double[8]). Below is a snippet of the error output:
$ dub build -c library-novtk -b release --compiler=ldc2

I’ve updated LDC to the latest version and ensured dependencies are up to date. Any guidance would be greatly appreciated. Thank you!
Thanks for reaching out. I’ve been using LDC v 1.28 for development and that version will still work. I still need to update the codebase to support newer compilers.
