Your first suggest link recommends the addition of -d32 option at:
Run => Run Configurations => Java Application => => (x)= Arguments => VM Arguments
When this is done, when I run the sketch, I get message box titled “Java Virtual Machine Launcher” with the error message:
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
In the console tab I see the error:
Unrecognized option: -d32
I do not know what to do about this. I considered installing 32 Bit Eclipse, but I do not see a 32 Bit option on the Eclipse download page.
Your second suggested link seems relevant only to Linux OS. My OS is Windows 7. I did not find a way to install “gnueabihf” in my Windows 7 OS, and if there is a Windows 7 equivalent, I do not know what it is.
