It's this a bug or my mistake for missed something?

my mistake is the same as yours,but the"EIGEN_DEPRECATED const unsigned int AlignedBit = 0x80"is bug?
cbachhuber commentedon Oct 16, 2018
The error is caused by a missing header inclusion, unistd.h is missing. This has been discussed before. Solution given here:
Put
#include <unistd.h>in System.h.lucasjinreal commentedon Oct 16, 2018
Problem solved, thanks.

Hi. I had a similar or the same problem. So I tried the solution above ('Put #include <unistd.h> in System.h.' from cbachhuber) but it didn't help.
But: after reading the following post I tried to Downgrade the Eigen to 3.2 and all the problems magically dissappeared :)
