问题描述

我正在尝试为在我的Ubuntu机器上工作的Raspberry Pi进行交叉编译.

I am attempting to get cross-compiling for Raspberry Pi working on my Ubuntu machine.

在最初的尝试中，我使用的是arm-linux-gnueabi编译器，该编译器在Ubuntu仓库中可用.我得到了这个工作.我能够建立我的所有依赖关系，并在我的cmake项目中使用交叉编译器.

During my initial attempts I was using the arm-linux-gnueabi compiler, which is available in the Ubuntu repo. I got this working. I was able to build all my dependencies and use the cross-compiler in my cmake project.

但是，我相信我应该使用hf版本，所以我切换到了arm-linux-gnueabihf.然后我意识到这对Raspberry Pi不起作用，因为它是armv6.

However, I believe I should be using the hf version, so I switched to arm-linux-gnueabihf. Then I realized that this does not work with Raspberry Pi since it is armv6.

经过一番谷歌搜索，然后我找到了来自GitHub的预制工具链.

After some Googling, I then found the pre-built toolchain from GitHub.

我下载了工具链，但是我不太了解如何安装"它.我将文件提取到我的主目录中.目录结构如下:

I downloaded the toolchain, but I don't really understand how to "install" it. I extracted the files to my home directory. The directory structure looks like this:

/gcc-linearo-arm-linux-gnueabihf-raspbian
    /arm-linux-gnueabihf
        /bin
            (contains g++, gcc, etc)
        /lib
            (contains libstdc++ library)
    /bin
        (contains arm-linux-gnueabihf-g++, arm-linux-gnueabihf-...)
    /lib
        (gcc lib stuff)

如果将目录更改为INNER bin文件夹，则可以从终端编译测试程序而没有任何问题.

If I change directory to the INNER bin folder I am able to compile a test program from the terminal without any problems.

~/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/
arm-linux-gnueabihf/bin$ g++ test.cpp -o test

然后我尝试在OUTER bin文件夹中编译一个测试程序，其中包含工具的前缀版本.

I then tried to compile a test program in the OUTER bin folder, which contains the prefixed versions of the tools.

 ~/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin$ 
 arm-linux-gnueabihf-g++ test.cpp -o test

但是，当我现在(从内部bin目录外部)尝试使用编译器时，它找不到工具链随附的libstdc ++共享库:

However, when I try to use the compiler now (from outside the inner bin directory), it is unable to find the libstdc++ shared library that comes with the toolchain:

arm-linux-gnueabihf-gcc: error while loading shared libraries: 
libstdc++.so.6: cannot open shared object file: No such file or directory.

此外，我希望能够使用编译器而不必导航到bin目录.因此，我尝试将OUTER bin目录(因为我想要带前缀的版本)和两个lib目录都添加到我的PATH中:

Furthermore, I want to be able to use the compiler without having to navigate to the bin directory. So I tried adding the OUTER bin directory (since I want the prefixed versions) and both lib directories to my PATH:

export PATH=$PATH:~/tools/.../bin
export PATH=$PATH:~/tools/.../lib
export PATH=$PATH:~/tools/.../.../lib

但是，这将导致相同的错误.我应该如何安装"工具链，以便可以像在Ubuntu仓库中使用交叉编译器一样在任何地方使用该工具链?

However, this results in the same error. How should I "install" the toolchain so that I can use the toolchain from everywhere, just like I can when I use the cross-compilers from the Ubuntu repo?

让我们交叉编译一个Pie！

首先在您的主目录中创建一个名为raspberrypi的文件夹.

进入此文件夹，然后下拉您上面提到的ENTIRE tools文件夹:

Go in to this folder and pull down the ENTIRE tools folder you mentioned above:

git clone git://github.com/raspberrypi/tools.git

如果我没看错的话，您想使用以下三个中的一个，gcc-linaro-arm-linux-gnueabihf-raspbian.

You wanted to use the following of the 3 ones, gcc-linaro-arm-linux-gnueabihf-raspbian, if I did not read wrong.

进入您的主目录并添加:

Go into your home directory and add:

export PATH=$PATH:$HOME/raspberrypi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin

到名为~/.bashrc

现在，您可以注销并重新登录(即重新启动终端会话)，或者在终端中运行. ~/.bashrc来在当前终端会话中获取PATH添加的内容.

Now you can either log out and log back in (i.e. restart your terminal session), or run . ~/.bashrc in your terminal to pick up the PATH addition in your current terminal session.

现在，确认您可以访问编译器arm-linux-gnueabihf-gcc -v.你应该得到这样的东西:

Now, verify that you can access the compiler arm-linux-gnueabihf-gcc -v. You should get something like this:

Using built-in specs.

但是，嘿！我这样做了，但库仍然不起作用！

我们还没有完成！到目前为止，我们仅完成了基础工作.

But hey! I did that and the libs still don't work!

We're not done yet! So far, we've only done the basics.

在您的raspberrypi文件夹中，创建一个名为rootfs的文件夹.

In your raspberrypi folder, make a folder called rootfs.

现在，您需要将整个/lib和/usr目录复制到此新创建的文件夹中.我通常会调出rpi图像并通过rsync复制它:

Now you need to copy the entire /liband /usr directory to this newly created folder. I usually bring the rpi image up and copy it via rsync:

rsync -rl --delete-after --safe-links pi@192.168.1.PI:/{lib,usr} $HOME/raspberrypi/rootfs

其中192.168.1.PI被Raspberry Pi的IP代替.

where 192.168.1.PI is replaced by the IP of your Raspberry Pi.

现在，我们需要编写一个cmake配置文件.在您喜欢的编辑器中打开~/home/raspberrypi/pi.cmake并插入以下内容:

Now, we need to write a cmake config file. Open ~/home/raspberrypi/pi.cmake in your favorite editor and insert the following:

SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_SYSTEM_VERSION 1)
SET(CMAKE_C_COMPILER $ENV{HOME}/raspberrypi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-gcc)
SET(CMAKE_CXX_COMPILER $ENV{HOME}/raspberrypi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-g++)
SET(CMAKE_FIND_ROOT_PATH $ENV{HOME}/raspberrypi/rootfs)
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

现在，您只需添加以下额外标志即可编译cmake程序:-D CMAKE_TOOLCHAIN_FILE=$HOME/raspberrypi/pi.cmake.

Now you should be able to compile your cmake programs simply by adding this extra flag: -D CMAKE_TOOLCHAIN_FILE=$HOME/raspberrypi/pi.cmake.

使用 cmake hello world 示例:

git clone https://github.com/jameskbride/cmake-hello-world.git 
cd cmake-hello-world
mkdir build
cd build
cmake -D CMAKE_TOOLCHAIN_FILE=$HOME/raspberrypi/pi.cmake ../
make
scp CMakeHelloWorld pi@192.168.1.PI:/home/pi/
ssh pi@192.168.1.PI ./CMakeHelloWorld
