I attempted to write a rockspec, but there's a linking problem that I've been trying to resolve for about four hours now and I haven't made any progress.

Below is the linking error, if anyone is interested and/or more experienced than me with building on Windows:

Error: Build error: Failed compiling module yaml.dll

I built libyaml as a static library; installing from luarocks also silently fails the same way when libyaml is built as a .dll.

leonardus commented 7 months ago

I've also tried building libyaml as a shared library, which allows to successfully compile, link, and install lyaml with the modified Rockspec, just with this error when trying to load ylaml (specifically when include('yaml') is called).
