Comment (by chtz@…):

 Replying to [comment:15 dbrake@…]:
 > a workaround for me might consist of providing a compile-time configure
 option for my library for turning off the expression templates for
 Boost.Multiprecision.  if they are on, require a minimum version of eigen.
 otherwise, let it ride with any version 3.2 or later.  i have an m4 macro
 for autoconf which finds eigen (does eigen provide such a macro? i didn't
 find one), and the et_on/off requirement could be written into the call.

 Eigen does not provide m4 macros. There is a preprocessor macro
 {{{EIGEN_VERSION_AT_LEAST(x,y,z)}}} and we provide a cmake module
 FindEigen3.cmake which also checks for the version number. The latter
 should be relativly easy to adapt to any language with basic regex
 support.
