编译OpenCV 3.4.16+CUDA 12时遇未定义标识符错误求助

问题描述 #

尝试编译带CUDA的OpenCV时出现编译错误，具体日志如下：

使用环境：

• nvidia-driver-525.60.13
• CUDA 12.0
• OpenCV 3.4.16

nvcc版本输出：

totar@totar:~/cv2/opencv-3.4.16/build$ nvcc --version

错误原因 #

OpenCV 3.4.16的CUDA模块依赖CUDA旧版API，而CUDA 12.0已移除texture模板、cudaUnbindTexture、textureReference这些接口，导致版本不兼容，编译失败。

解决方案 #

方案1：降级CUDA版本 #

将CUDA降级到OpenCV 3.4.16支持的版本，推荐CUDA 11.4或CUDA 10.2，这两个版本与OpenCV 3.4.x系列兼容性较好。

方案2：升级OpenCV版本 #

升级到OpenCV 4.5.5及以上版本，这些版本已适配CUDA 12.0的API变更，可正常编译。

方案3：手动修改OpenCV源码（不推荐） #

若必须保留当前版本组合，需手动修改OpenCV的CUDA相关源码，用CUDA 12.0支持的纹理对象（texture object）替换旧的纹理引用接口。但该操作需熟悉CUDA API与OpenCV源码结构，修改量较大，易引入新问题。
