Hi @teetat, welcome to the Cayenne Community.
Can I ask if you’re able to compile any sketch without error on that machine? Say, one of the example sketches from File > Examples > Built-In Examples in the Arduino IDE? I do not think this is a Cayenne issue so much as an issue with the Arduino IDE on Windows XP.
When I researched the error message it seems to be XP specific:
It looks like some users on the Arduino forum have had success with running their IDE in compatibility mode for Windows 98, as well as changing the compatibility mode settings for
ld.exe to the same: See this thread: http://forum.arduino.cc/index.php?topic=310950.msg3013686#msg3013686
This page has a proposed fix too, though be careful with exectuables downloaded from 3rd party websites.
