To the Community,
Hello. I have used Eigen successfully on several of my robotics projects with the Arduino Due 32-bit microtroller on a Windows 7 64-bit PC. I use Eigen to perform extensive matrix operations as part of the feedback control system.
All compiled normally on the Arduino-1.6.6 IDE, which uses the GCC compiler, until I upgraded to Windows 10 on a 64-bit PC. I simplified the Arduino program which reproduces the compile error:
#include <Eigen320.h>
void setup() {
}
void loop() {
}
Here's the compile error. Your help is appreciated. Thank you.
