ctypes错误：libdc1394错误：无法初始化libdc1394 [英] ctypes error: libdc1394 error: Failed to initialize libdc1394

问题描述

我试图将我的程序编译成共享库，我可以使用从Python代码使用ctypes。

I'm trying to compile my program to a shared library that I can use from within Python code using ctypes.

库使用此命令编译良好： / p>

The library compiles fine using this command:

g++ -shared -Wl,-soname,mylib -O3 -o mylib.so -fPIC [files] `pkg-config --libs --cflags opencv`

然而，当我尝试使用ctypes

However, when I try and import it using ctypes

from ctypes import *
mylib = CDLL("/path/to/mylib.so")
print mylib.test() // Expected output: Hello World

我得到以下错误：

libdc1394 error: Failed to initialize libdc1394

发生了什么事？

推荐答案

非常令人沮丧的是，没有人真正展示一个具体的解决方案。我有安装OpenCV后的这个问题。对我来说，删除此警告的最简单的解决方法是禁用此驱动程序：

Very frustrating that nobody actually shows a concrete solution. I had this issue after installing OpenCV. For me the easiest solution to remove this warning was actually to disable this driver:

sudo ln /dev/null /dev/raw1394
