My Python script works just fine, but something wrong with the exe
generated by Pyinstaller.
*Error message:*
Traceback (most recent call last):
File "main.py", line 3, in <module>
print(XReal.get_arr())
File "XReal.py", line 9, in get_arr
ptr = self.dll.GetEuler()
OSError: exception: access violation reading 0x0000000000000000
*Source code:*
XReal.py:
import ctypes
class xreal:
def __init__(self):
self.dll = ctypes.CDLL('AirAPI_Windows.dll')
self.dll.StartConnection()
self.dll.GetEuler.restype = ctypes.POINTER(ctypes.c_float)
self.arr = (ctypes.c_float * 3)()
def get_arr(self):
ptr = self.dll.GetEuler()
ctypes.memmove(self.arr, ptr, ctypes.sizeof(self.arr))
return list(self.arr)
XReal = xreal()
*main.py:*
from XReal import XReal
while True:
print(XReal.get_arr())
import vispy # If this line is commented out, the exe generated works as
expected.
*The pyinstaller command:*
pyinstaller main.py
*Environment information:*
OS: Win11
Python: 3.7.5
Pyinstaller: 5.13.2
vispy: 0.6.4
AirAPI_Windows.dll: GitHub - MSmithDev/AirAPI_Windows

Any suggestions?
Thanks in advance.
