我希望这里有人知道 PyHLA。基本上它允许您在 python API 中使用 C++ 代码。我正在尝试使用 cmake 用 python3.6 构建它，因为我需要用它运行莫尔斯模拟，而莫尔斯至少需要 python3.3。我有 python 3.6 和 2.7，我不知道为什么，但我不能用 python 3.6 构建。

这就是我要运行的cmake . -DPYTHON_EXECUTABLE=/usr/bin/python3.6：

-- Configuring PyHLA version 1.1.1
Python 3.6.9
-- Using Python: 
CMake Error at CMakeLists.txt:29 (message):
  You need at least Python 2.5, found:
-- Configuring incomplete, errors occurred!
See also "/home/mohamed/Documents/PyHLA-1.1.1-Source/CMakeFiles/CMakeOutput.log".

当我运行时cmake . -DPYTHON_EXECUTABLE=/usr/bin/python2.7，我得到：

-- Configuring PyHLA version 1.1.1
-- Found PythonInterp: /usr/bin/python2.7 (found version "2.7.17") 
-- Using Python: 2.7.17

问题是当我使用python2.7构建并尝试使用python3.6时，我当然会收到错误：

Import Error: undefined symbol _Py_ZeroStruct

有没有人设法将 hla 与 Morse 一起使用？
