most language toolchains are complicated, except for Go, you only need to download a package, unpack it, set some environment variables and off you go

python. lol

C++ - boost, anyone? cmake?

rust is also quite simple but it's made of several parts but they bundle them in the installer

idk what php is, it's a very old and mostly has been static for the last decade so i'd guess it's also simple, just apt get and basta
