I was playing around with building Macaulay2 in OpenIndiana and was puzzled when it failed detecting eigen.
I checked out
config.log
and noticed that the check failed when one of the eigen headers tried to#include <cmath>
, and it couldn't find the file. It turns out that it was trying to compile usinggcc
instead ofg++
!It's a trivial fix, just adding
AC_LANG([C++])
, so I'm skipping the builds.Cc: @MichaelABurr
