Ported open source projects

QNX ports of open source projects provided by QNX don't include build system configurations within the open source repositories themselves.

Instead, QNX maintains a separate repository that contains these configuration files.

Ultimately, cross compilation of the ported projects only requires a simple call to the make utility:

make -C build-files/ports/project_name

All QNX ports use QNX recursive Makefiles, regardless of the build system used in the open-source project.

This offers the following advantages:

• A common and simple interface.

• "Out-of-source" builds (generated artifacts are stored outside the source tree).

• Cross compilation support for all architectures (with separate folders for each architecture).

• Partial build support (for example: only x86 architecture).

For an example of creating a recursive Makefile, visit the "A single application" page in the Programmer's Guide.

The following sections cover various build systems and provide tips for cross compiling existing projects for QNX.
