problem in 'make'

[biopolyhedron]

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!

There is a major update to Spectra recently, and the code in the master branch is not compatible with older versions. You can download the v0.9.0 version instead.

Thank you, the installation works now with Spectra v0.9.0.
