Create programs with the program-template

We've created a program template that you can use to bootstrap your program.

Note the program-template as well as the light-sdk and proc macros are experimental convenience helpers, and their APIs are subject to change.

1. Install the CLI

Package Manager	Command
npm	npm install -g @lightprotocol/zk-compression-cli
Yarn	yarn global add @lightprotocol/zk-compression-cli

2. Initialize your program

Requires version v0.15.1 or higher.

light init testprogram

This initializes an anchor program with a basic counter program template using compressed accounts.

Now, run:

anchor build

cargo test-sbf

Common Errors

'assert.h' file not found - during compilation.

Fix: 
In your terminal, run:
1. export CC=$(xcrun -find clang)
2. export SDKROOT=$(xcrun --show-sdk-path)
3. cargo clean
4. anchor build
