Building Own Application for QnxScreen

Generate Makefiles with CMake

For general information about CGI Studio Build System and CMake properties available to configure Candera applications refer to CGI Studio Build System.

To configure and generate makefiles for compiling the CGI Player, follow below steps:

Open

terminal. Set the environment. This step is mandatory. Omitting this step will cause building with the host systems compiler instead of cross compiling.

call C:\Users\<username>\qnx<version>\<version>\qnxsdp-env.bat

From this console open CMake.

Point CMake to source directory

Folder containing top-level "CMakeLists.txt", e.g.
```
 /cmake/Candera/Player
```

Point CMake to ~~build~~binary directory

May not exist, create folder with CMake if necessary
Root directory for generated makefiles / solutions
Root directory for build artifacts

Configure

Specify Ninja Makefiles as generator for the project
Specify tool-chain file for cross-compiling

Select the toolchain-file from the delivery (adapt for your toolchain installation and application specific needs)

 /cgi_studio_devices/src/QnxScreen/ToolchainFiles/GCC-toolchain-<board>-QnxScreen-QNX.txt

Adapt the CMake settings if necessary, e.g.:

CMAKE_BUILD_TYPE-> Debug or Release
Press Configure

Press Generate

Building Application

: Use same Command Prompt window for all steps.

QNX environment variables first have to be set with qnxsdp-env.bat (QNX70\).
Open CMake GUI and configure the project (e.g Player, CourierSampleApp, CitDemoApp) according to Generate Makefiles with CMake
After generating your cmake files, simply navigate to the specified build directory (binary directory created in CMake GUI) and type "ninja" to start the build.
