Hello Ralph
SSP 1.1.0 alpha introduces version 5.3 of GUIX. This version will only work with resource/specification files generated in GUIX Studio 5.3.0.x. The files currently found in the project will only work with GUIX 5.2.5 (SSP 1.0.0) and hence will not compile with 1.1.0 alpha. You can download full version of GUIX Studio 5.3.0.1 for Synergy from the Gallery. You'll have to open the .gxp file in GUIX Studio and navigate to File >> Generate all Project Files.
However, I highly advise that you wait until the end of this week, when stable version of SSP 1.1.0 will be released as it fixes some important bugs in GUIX Adaptation Framework. Around then, there should also be an updated Hello World example available for download from the Renesas website
Regards
