Compile error in Linux

Video card: Tesla V100
CUDA version: 9.2

I configure makefile to：

GPU=1
CUDNN=1
CUDNN_HALF=1
OPENCV=1
AVX=1
OPENMP=1
LIBSO=1
ZED_CAMERA=0
ZED_CAMERA_v2_8=0
USE_CPP=0
DEBUG=0

ARCH= -gencode arch=compute_35,code=sm_35 \
      -gencode arch=compute_50,code=[sm_50,compute_50] \
      -gencode arch=compute_52,code=[sm_52,compute_52] \
            -gencode arch=compute_70,code=[sm_70,compute_70]

But I got the following mistakes：

./src/network_kernels.cu(364): warning: variable "l" was declared but never referenced
./src/network_kernels.cu(694): error: identifier "cudaGraphExec_t" is undefined
./src/network_kernels.cu(697): error: identifier "cudaGraph_t" is undefined

./src/network_kernels.cu(725): error: identifier "cudaGraphLaunch" is undefined

7 errors detected in the compilation of "/tmp/tmpxft_00003086_00000000-9_network_kernels.compute_70.cpp1.ii".
Makefile:185: recipe for target 'obj/network_kernels.o' failed

How can I solve this problem, thank you very much for your help?

CUDA graphs is a new feature that was recently added to Darknet. Is it possible that CUDA 9.2 doesn't support it?

Yes, now Darknet requires CUDA 10.2 or higher. Preferably CUDA 11.2.

Or you can download 2 weeks old Dartnet, that works well with old CUDA 9.x https://github.com/AlexeyAB/darknet/archive/64efa721ede91cd8ccc18257f98eeba43b73a6af.zip

Now I have downloaded 2 weeks old Dartnet as you said, but I encountered a new error when compiling
as follows:

gcc: error trying to exec 'cc1plus': execvp: No such file or directory
Makefile:185: recipe for target 'obj/convolutional_kernels.o' failed
make: *** [obj/convolutional_kernels.o] Error 1

I checked my g++ and gcc versions. Is it because of version issues?
dpkg -l | egrep "g\+\+|build-essential"

You're now using this issue for a brand new problem.

But are you seriously attempting to use g++4? Is that v4.5? The current version is g++9. My Ubuntu has v9.3. The version you are using must be from ...2012? I don't know what kind of system you are on, but you'll most likely have to upgrade to something modern.
