python - 交叉编译python for arm时导入zlib错误

Question

我正在为 arm 编译 python，在我的 ubuntu 上的虚拟框中。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”，我得到一个错误，说它不能导入 zlib。我一直在在线尝试许多解决方案，但没有一个对我有用。唉，我最后的希望是试图在这里发布这个问题。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 因为我正在尝试在机器上安装 pip。我无法做到，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 Ubuntu 12.04.5。以下是我正在采取的步骤...

echo "Compilation complete (hopefully successfully). Now, connect to the Sandisk device's wifi hotspot,"
echo "and then run the local ./upload_python.sh script."

Answer 1

所以我弄清楚出了什么问题。我变了

rm -r lib2to3 idlelib lib-tk site-packages config lib-dynload

至

rm -r site-packages config lib-dynload

此外，无论何时运行构建脚本，请务必在每次运行开始时删除 pybuild 目录。在随后的运行中，由于 pybuild 目录仍然存在，它会出于某种原因删除 .so 文件。
