我试图编译暗网时出错了。[暗网] Error1

Question

我在jetson中做Makefile时出错了

这是一条错误消息。

我将其设置如下，并编译了它，但出现了一个错误。你知道问题出在哪里吗？

GPU=1
CUDNN=1
CUDNN_HALF=1
OPENCV=1
AVX=0
OPENMP=0
LIBSO=1
OPENCV_DNN=1
TENSORRT=0
RTSP=1

1.将作为jetpack一部分的文件复制到darknet使用的正确位置。

# add the cudnn header file to the include folder
sudo cp /usr/include/cudnn.h /usr/local/cuda/include

# copy the cudnn shared object library files to the cuda library folder
sudo cp -P /usr/lib/aarch64-linux-gnu/libcudnn* /usr/local/cuda/lib64

# change the ownership and read writes for the jetson nano user
sudo chmod a+r /usr/local/include/cudnn*.h /usr/local/cuda/lib64/libcudnn*

使用build_darknet_nano.sh 2.编译暗网

事实证明，src/representation_layer.c没有被编译，这就是为什么奇怪的错误会出现，说它找不到函数。我通过在构建命令中包含c文件来解决这个问题。

我已经创建了这个build_darknet_nano.sh脚本，您可以运行这个脚本来编译jetson上的黑网：

https://gist.github.com/Raunak-Singh-Inventor/4f1a20808bf2579ec938f8e050bf6514

要运行该程序，请执行以下操作：

将此代码保存在名为build_darknet_nano.sh的文件中

chmod u+x build_darknet_nano.sh

./build_darknet_nano.sh

然后就到了。这将成功地在Jetson上编译出暗网。试着运行./darknet看看是否一切正常。
