1. Compile the Pascal Code
Make sure you have Free Pascal (with WebAssembly support) installed.
Compile the Pascal source to WebAssembly:
ppcrosswasm32 -Twasi -ohello.wasm hello_wasm.pas2. Serve the files
You need to serve these files over HTTP to load WebAssembly in the browser.
fpc -ohttp_server http_servers.lpr #and other options that may applied
./http_server
HTTP Server running at http://localhost:8080🛠️ Author & License
