# FastWave
> Cross-Platform Wave Viewer

### Start:
1. Install [Rust](https://www.rust-lang.org/tools/install)
2. Install [Node.js](https://nodejs.org/)
3. `cargo install cargo-make`
4. `makers install`
5. `makers start`
Troubleshooting:
- In case of Tauri compilation errors, install system dependencies: https://beta.tauri.app/guides/prerequisites/
- Possible Tauri runtime errors in terminal of VSCode installed from Linux Snap package manager:
```
Failed to load module "colorreload-gtk-module"
/usr/lib/x86_64-linux-gnu/webkit2gtk-4.1/WebKitNetworkProcess: symbol lookup error: /snap/core20/current/lib/x86_64-linux-gnu/libpthread.so.0: undefined symbol: __libc_pthread_init, version GLIBC_PRIVATE
```
Fix it by installing VSCode directly from official `.deb` bundle or try to unset multiple env variables - more info in https://stackoverflow.com/questions/75921414/java-symbol-lookup-error-snap-core20-current-lib-x86-64-linux-gnu-libpthread
---
### Steps before pushing:
1. `makers format`
---
### Production build:
1. `makers bundle`
2. Runnable executable is in `target/release`
3. Installable bundles specific for the platform are in `target/release/bundle`
