asm / socket.h：没有这样的文件或目录交叉编译Dart for Raspberry pi

Question

我正在使用这里的指令交叉编译Dart运行时。

我已按指定安装了所有依赖项。 我还用必要的工具链克隆了git存储库。

我正在使用此命令运行运行时编译：

./tools/build.py -m release -a arm --toolchain=../tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf runtime

编译开始没有问题然后它停止与此错误：

我错过了任何依赖或包裹吗？

Answer 1

我遇到了同样的问题。 在我的ubuntu 14.04系统/ usr / include / asm上不存在。 它被称为asm-generic。 我sym链接它，构建能够继续。

cd /usr/include
sudo ln -s asm-generic/ asm

之后构建能够继续。

Answer 2

这可能是因为您尝试在没有正确设置某些包含路径的情况下构建应用程序，例如在64位平台上使用32位gcc。 解决：

sudo apt-get install gcc-multilib

Answer 3

我不确定为什么会这样，但有时/usr/include/asm会被删除。 我的队友看了他们的Ubuntu x86-64工作站，发现asm符号链接是：

0 lrwxrwxrwx 1 root root 20 May 22  2013 /usr/include/asm -> x86_64-linux-gnu/asm

并且重新创建它的命令是：

$ cd /usr/include
$ sudo ln -s x86_64-linux-gnu/asm asm

/usr/include/asm-generic中的文件有时（但不总是）等同于x86-64特定目录中的文件; 所以很难推荐将其作为一种解决方法。
