为 arm 交叉编译 python 时导入 zlib 错误
import zlib error when cross compiling python for arm
我正在为 arm 编译 python，在我的 ubuntu 虚拟框中。在所有这些步骤 运行 之后，我将 python 放在带有 arm 处理器的机器上。我在终端中 运行 命令 "python" 并收到一条错误消息，指出它无法导入 zlib。我一直在网上尝试许多解决方案，none 对我有用。唉，我最后的希望就是在这里尝试 post 这个问题。当这条线时，我能够让它在目标机器上工作：
rm -r lib2to3 idlelib lib-tk site-packages config lib-dynload
是这样写的：
rm -r lib2to3 idlelib lib-tk site-packages config lib-dynload distutils
我需要 distutils，因为我想在机器上安装 pip。我无法做到这一点，因为我相信 distutils 依赖于 zlib，但是在为目标机器交叉编译后我无法让 python 找到 zlib。我正在 运行ning Ubuntu 12.04.5.The 以下是我正在采取的步骤...
