Use CLion with Symbian applications¶

CLion is a CMake-aware C++ IDE. This project uses its CMake profiles to keep host tools and 32-bit ARM guest code separate. The editor can index the ARM headers and source using the same compiler settings as the build. A saved Run configuration launches the example through the SDK's emulator supervisor; a separate Remote Debug configuration attaches ARM GDB to the guest.

The GUI example open in IntelliJ IDEA with the CLion plugin: source tree, ARM profile and GUI Run control.

The prepared GUI example in IntelliJ IDEA with the CLion plugin. The toolbar shows the selected ARM CMake profile and saved GUI Run configuration. The IDE capture shows configuration and source indexing, not a running guest.

Step	Guide	What to check
1	Configure profiles	Open `examples/gui_app`; load `clion-arm`; reload CMake
2	Run and debug	Use GUI Run for a visible app and GUI Debug for guest breakpoints
3	Inspect indexing and advanced paths	Compilation databases, retained sessions and manual GDB

The Build a real GUI app explains the underlying ELF, E32, firmware and emulator steps. CLion displays source and controls these tools; it does not turn an ARM ELF into a host executable. A generated app may use the standalone project guide instead of the source example.

Develop the SDK itself¶

Open the repository root and select guest-probes-armv6 or guest-probes-armv5t (the local IDE profiles have a clion- prefix). These profiles build the current runtime, device APIs, WebSocket codec, TLS wrapper and guest concurrency archives. Applications in that graph use the same archives and prefer the workspace's current public headers. Editing an SDK header or implementation therefore updates the application build and its compiler context without exporting an SDK first.

The active SDK still supplies preserved platform headers, import proxies, host tools, and the pinned Abseil and Mbed TLS dependency archives. Standalone application projects consume the exported SDK. After changing the selected compiler installation, configure with cmake --fresh --preset guest-probes-armv6 to replace its compiler cache. Each profile writes its own compile_commands.json; an ARM ELF build does not establish loader or physical device compatibility.
