Makefile:1627: recipe for target 'abundances.o' failed
The relevant code in src/abundances.cpp looks like this:
Eigen::VectorXd v;
double m = 0;
v = U.rowwise().sum();
m = v.colwise().sum()(0);
For some reason Eigen thinks that v.colwise().sum() cannot be treated as
a one-dimensional vector, which smells like a bug in Eigen. Changing the
last line to
m = v.colwise().sum()(0, 0);
seems to do the trick.
