problem in 'make' #50
Description
Dear gabraham,
I downloaded flashpca2 using git clone as mentioned in README.md , and installed Eigen 3.3.9 and Spectra as instructed without problem. Then I entered flashpca/ folder, changed the including folders of eigen, boost and spectra in Makefile and then 'make', then I got these error informations (too long, I just copy the first and last few lines):

What could I do for fixing it? Thank you!
