Hello,
I was pleasantly surprised yesterday to see that a program using Eigen
compiles and runs without problem so far on an ARM8 cpu (using the
OpenEmbedded linux distribution). The only minor compilation problem I
had so far was with std::pow (see below). The cross compiler is gcc
4.3 (internaly built by openEmbedded)

I will run the test directory from eigen later this week to see if
everything is working.
