First you need to install Rust as well as a linker and the usual build tools such as gcc, make etc.
See this page and follow instructions to install everything.
Once you have these, get the code:
git clone [email protected]:gtamas/schematicsgui.git /some/path
Finally, run build:
cd /some/path
cargo build
cargo run
This should build and start the app.
The above command will create a dev build with debug stuff included. If you want a optimized ("release") build, run this instead:
cargo build --release
Once the build is done, you can find the binary here:
./target/release/schematics-gui
