I try to build the Eigen library on a ARM with cxx11. The library builds with ARM GCC 4.8.* but not with ARM 4.9.*
It also builds on a native environment. See: https://travis-ci.org/diydrones/ardupilot/builds/88184030
Other people reported the same problems: http://lists.freebsd.org/pipermail/freebsd-current/2014-January/048130.html
As parts of the libs are protected by guard DEFs, compilation on GCC 4.8 was only possible with such a construct:
#pragma once
#pragma GCC diagnostic push
#define RAND_MAX __RAND_MAX
#pragma GCC diagnostic ignored "-Wshadow"
#pragma GCC diagnostic ignored "-Wfloat-equal"
#define _GLIBCXX_USE_C99_FP_MACROS_DYNAMIC 1
..
Here is the short version of my compiler error:
/home/travis/build/diydrones/ardupilot/libraries/AP_Eigen/AP_Eigen.h:17:81: note: #pragma message: std::lgamma*() does not exist in this environment.
#pragma message("std::lgamma*() does not exist in this environment.")

Please fix this fast, it cannot be that half of the standard library cannot be used with ARM. |
