Darknet: Can't get GPU working on MAC

[chitalian]

Getting this Error when trying to run make with GPU = 1

Currently using Nvidia 750m
I did install Cuda via Nvidia's website.

encv -L/usr/local/cuda/lib64 -lcuda -lcudart -lcublas -lcurand -lstdc++ clang: warning: argument unused during compilation: '-pthread' [-Wunused-command-line-argument] ld: warning: directory not found for option '-L/usr/local/cuda/lib64' ld: library not found for -lcuda clang: fatal error: linker command failed with exit code 1 (use -v to see invocation) make: *** [libdarknet.so] Error 1

i have been getting the same error, now i can't make with GPU = 0. i have downgraded to apple clang 8.1.0 . but still nothing

I had the same problem.
This link solved it https://groups.google.com/forum/#!searchin/darknet/directory$20not$20found$20for$20option$20$27-L$2Fusr$2Flocal$2Fcuda$2Flib64$27%7Csort:date/darknet/vc2ODK6uV2k/gNwLT102BAAJ

What’s the error?

Getting the same issue, cannot compile with GPU = 1
My MBP config:

macOS 10.13.4
Nvidia 750M
CUDA toolkit 9.2
Xcode 9.2
Does anyone got the solution?

@Ntisnotawizard
My error was:

clang: warning: argument unused during compilation: '-pthread' [-Wunused-command-line-argument]
ld: warning: directory not found for option '-L/usr/local/cuda/lib64'
ld: library not found for -lcuda
clang: fatal error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [libdarknet.so] Error 1

CUDA 9.2 has '/usr/local/cuda/lib' instead of '/use/local/cuda/lib64' like older CUDA installation did.

In the Makefile, I changed the following line:
LDFLAGS+= -L/usr/local/cuda/lib64 -lcuda -lcudart -lcublas -lcurand
to this:
LDFLAGS+= -L/usr/local/cuda/lib -lcuda -lcudart -lcublas -lcurand
and it compiled.

Hmm...looks like darknet has been updated to support that. I see it's using the correct path on my system, but still getting library not found for -lcuda. Looking in that lib directory, I don't a libcuda.dylib though. But there is a libcudart.dylib,libcblas.dylib, andlibcurand.dylib`. I've got cuda 10 installed.

Perhaps it's been renamed?
