Using -mfloat-abi = hard and -mfpu = vfp / neon Codesourcery Lite 2013.05-24

To use vfp or neon, I added -mfpu = vfp and -mfloat-abi = hard for my cross-compilation. The program is a very simple hellofloat.cpp, which then no longer compiles with Sourcery CodeBench Lite 2013.05-24.

#include <string> #include <iostream> using namespace std; int main() { double val=1.04; cout << "Hello Float: " << val << endl; }

Compilation Instructions:

 arm-none-linux-gnueabi-g++ -o armhf-main main.cpp -march=armv7-a -mfloat-abi=hard -mfpu=neon

Am I confused since Codesorcery should support armhf compilation?

Sourcery CodeBench Lite toolkit does not support armhf. Academic or personal publications are also not issued.

To do this, you need to purchase standard or professional versions.

As an alternative, I believe that the cross-compiler packages for Ubuntu support the configuration you need (in fact, only this configuration).

If you are not using Ubuntu, then Linaro ready-made tools should be exactly what you need. (Ubuntu cross-compiler packages are also created by the Linaro people, although they use the deb deboval / Ubuntu system).
