跨gdb找不到python

Question

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，即我已经python2.7.exe安装了C:\msys64\mingw64\bin并且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`

我还添加了C:\msys64\mingw64\lib我有的地方，libpython2.7.dll.a但我仍然遇到相同的错误。

我也尝试在windows上安装python并设置所有路径，但仍然是同样的错误。

如何让 gdb 找到 python？

Answer 1

您必须设置环境变量：

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

PYTHONHOME 变量指的是 python 解释器：

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

我在 msys2 下构建了自己的 gdb，它在设置正确的环境变量后可以工作：

Microsoft Windows [Version 10.0.16299.19]

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

我的配置命令行是：

./configure --target=x86_64-linux-gnu --prefix=/home/tiit/gdb-7.11-bin --with-python=/mingw64/bin/python.exe --enable-static=yes
