nvcc fatal : Unsupported gpu architecture 'compute_20' about ccminer-cryptonight HOT 11 OPEN

I was able to fix this by commenting and uncommenting some lines in my Makefile at line 395. I was able to compile with these lines:

#NVCC_GENCODE           = -gencode=arch=compute_35,code=\"sm_35,compute_35\"
NVCC_GENCODE            = -gencode=arch=compute_30,code=\"sm_30,compute_30\" -gencode=arch=compute_35,code=\"sm_35,compute_35\"
#NVCC_GENCODE = -gencode=arch=code=\"sm_20\" -gencode=arch=compute_30,code=\"sm_30,compute_30\" -gencode=arch=compute_35,code=\"sm_35,compute_35\"

from ccminer-cryptonight.

After more research I found that the newest cuda version (9.0) doesn't support compute_20 anymore. This means that you have two options, disable the compute_20 target or install cuda version 8.0. If your GPU supports newer compute architectures you should use the newest cuda version and disable compute_20.

Leave the "-v", that worked for me:

-Xptxas "-v" $(NVCC_GENCODE) --maxrregcount=80 .........

from ccminer-cryptonight.

Just in case it helps someone, combo of both @pingiun suggestions got it compiling successfully on my machine (16.04 w/ GTX 780). In Makefile replace NVCC_GENCODE block with :

NVCC_GENCODE = -gencode=arch=compute_30,code=\"sm_30,compute_30\" -gencode=arch=compute_35,code=\"sm_35,compute_35\"

and remove -abi=no (preserve the -v).

@pingiun Unfortunately, that didn't work out for me. I'm now getting this error.

I have the same problem.

from ccminer-cryptonight.

I've removed "-abi=no -v" from makefile, ran make again. Got this error:

ptxas fatal : Unknown option 'gencode'
Makefile:1155: recipe for target 'cryptonight/cryptonight.o' failed
make[2]: *** [cryptonight/cryptonight.o] Error 255

in the file Makefile.am find each line that contains
$(NVCC) $(JANSSON_INCLUDES) -I. @CUDA_INCLUDES@ @CUDA_CFLAGS@ -gencode=arch=compute_20,code="sm_21,compute_20" -o $@ -c $<
or
$(NVCC) $(nvcc_FLAGS) -gencode=arch=compute_35,code="sm_35,compute_35" -o $@ -c $<

after salsa_kernel.cu and replace the whole line with

$(NVCC) $(nvcc_FLAGS) --maxrregcount=64 -o $@ -c $<

I don't know how this got left in but it allow a clean compile.

then run
./autogen.sh
./build.sh

Still getting this error,
