## Build

- Install Lazarus 2.0+ and FPC 3.0.4+
- Install RichMemo package
- Run Lazarus IDE, then open project **CalcToolBox.lpr**
- Build the project.

### Reduce file size

Default build binary file size is very large (> 30M), to reduce file size, please open project option dialog.
- in **Debugging** tab, remove option
  - **Generate info for the debugger**
  - **Display line numbers in run-time error backtraces**
- in Compilation and Linking, select
  - **Smart linkable**
  - **Link smart**

Then rebuild.
