跨gdb找不到python答案

【问题标题】：Cross gdb can't find python跨gdb找不到python
【发布时间】：2016-07-03 21:19:35
【问题描述】：

我使用 MSYS2/MINGW64 在 Windows 上构建了一个支持 python 的交叉 gdb。我已经在MINGW64中安装了python，即我在C:\msys64\mingw64\bin中有python2.7.exe，这个地址在我的路径中。

运行 gdb 时出现以下错误

 Could not find platform independent libraries <prefix>
 Could not find platform dependent libraries <exec_prefix>
 Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
 ImportError: No module named site`

我还在libpython2.7.dll.a 的位置添加了C:\msys64\mingw64\lib，但我仍然遇到同样的错误。

我也尝试在windows上安装python并设置了所有路径，但还是同样的错误。

如何让 gdb 找到 python？

【解决方案1】：

你必须设置环境变量：

PYTHONPATH=C:\msys64\mingw64\lib\python2.7;C:\msys64\mingw64\lib\python2.7\lib-dynload;

PYTHONHOME 变量引用 python 解释器：

PYTHONHOME=C:\msys64\mingw64\bin\pyhon.exe

我在 msys2 下构建了自己的 gdb，设置正确的环境变量后它可以工作：

C:\Users\tiit>echo %PYTHONHOME%
C:\msys64\mingw64\bin\pyhon.exe

C:\Users\tiit>echo %PYTHONPATH%
C:\msys64\mingw64\lib\python2.7;C:\msys64\mingw64\lib\python2.7\lib-dynload;

C:\Users\tiit>C:\msys64\home\tiit\gdb-7.11-bin\bin\x86_64-linux-gnu-gdb.exe
