如何为 RasPi3 交叉编译 [英] How to cross-compile for RasPi3

问题描述

我目前正在尝试为我的 Raspberry Pi 3 交叉编译 Qt 5.7.这是我的第一次交叉编译尝试，所以请多多关照.:)

I am currently trying to cross-compile Qt 5.7 for my Raspberry Pi 3. This is my first cross-compiling atempt, so please be kind. :)

在 Qt Wiki 上，我找到了 Raspberry Pi 2 的说明，我目前正在尝试对其进行调整.

On the Qt Wiki I found instructions for the Raspberry Pi 2, which I am currently trying to adapt.

RasPi 2 的编译行如下:

The compile line for RasPi 2 is as follows:

./configure -release -opengl es2 -device linux-rasp-pi2-g++ -device-option 
CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- 
-sysroot ~/raspi/sysroot -opensource -confirm-license -make libs 
-prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v

我替换了选项

-device linux-rasp-pi2-g++

由

-device linux-rpi3-g++

正如我在 raspi-tools 文件夹中找到的那样.

as I found within the raspi-tools folder.

现在我被困在选项中

CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-

在 ~/raspi/tools/ 文件夹中，我看不到任何明显与 raspi3 相关的条目.只有 arm-bcm2708/ 文件夹.不应该有一些 bcm2837 条目吗?这是否意味着尚不支持 RasPi 3 还是我遗漏了什么?

as in the ~/raspi/tools/ folder I cannot see any obviously raspi3-related entry. There is only the arm-bcm2708/ folder. Shouldn't there be some bcm2837 entry? Does that mean there is no support for RasPi 3 yet or am I missing something?

感谢您的任何提示.

推荐答案

arm-bcm2708/ 文件夹只是一个名称.它包含几个构建工具链.也可以使用系统安装的工具链.所以我在我的构建机器(Debian GNU/Linux)上安装了包 g++-arm-linux-gnueabihf 并使用了这个配置调用:

The arm-bcm2708/ folder is just a name. It contains several build tool chains. It's perfectly fine to use system-installed tool chains as well. So I installed the package g++-arm-linux-gnueabihf on my build machine (Debian GNU/Linux) and used this configure call:

./configure -release -opengl es2 -device linux-rpi3-g++ 
  -device-option CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf- 
  -sysroot /home/fs/raspi/sysroot -opensource -confirm-license 
  -make libs -prefix /usr/local/qt5pi -extprefix /home/fs/raspi/qt5pi 
  -hostprefix /home/fs/raspi/qt5 -v
