cargo build-bpf does not work on windows

Problem

cargo build-bpf does not work on windows

It took me a while to understand that it just seems like the command doesn't work on windows or isn't supported
https://docs.solana.com/cli/install-solana-cli-tools I installed rust and the solana cli
https://github.com/solana-labs/solana-program-library then followed the readme here to build the token program

UserFolder\solana-program-library> cargo build
[...]
UserFolder\solana-program-library\token\program> cargo build-bpf
error: no such subcommand: `build-bpf`

Proposed Solution

1. If not supported yet, can we have the command return an error at least? Instead of "no such subcommand" leaving the developer wondering if his setup is wrong
2. If it is supposed to be supported then there is problem a problem to fix :)

Did you check if the executable cargo-build-bpf is located within your $PATH and that cargo build-bpf is run in a directory with Cargo.toml?

Yes we currently don't support native windows for cargo-build-bpf unfortunately. Would using WSL be an option?

[Arrowana]

@mvines I switched to a full setup in WSL, then I can develop. I don't think requiring WSL for a windows setup is great, the developer should be free to go for full Windows or full Linux (through WSL if he wants to).

Since windows can be used to do most of the other things, it seems like this subcommand has to exist but throw something, so solution 1. What do you think?

Is this as simple as adding cargo-build-bpf in https://github.com/solana-labs/solana/blob/master/scripts/cargo-install-all.sh#L62-L68 then having a simple executable which can print "build-bpf not supported on windows" that we build on windows instead of the real one?

Yep, this would be a fine solution until native windows support for development is available.

This was fixed in #20276 -- it currently requires a bash-compatible shell, but at least it's a start!
