Ffmpeg fails to build on ubuntu linux with cuda 11.2

Graphics / Linux Linux

When I try to build ffmpeg following this instruction:
https://developer.download.nvidia.com/designworks/ffmpeg/secure/Using_FFmpeg_with_NVIDIA_GPU_Hardware_Acceleration_v01.4.pdf?64ijjPUtWwEl6U_nUulM39q_O8qYO5liPrdpo-FLR-HdmwtCUYkk4uKhxlzQfmqkHT9yIOItPK2VwDKVjYNDbmqP6b92tpkWyOnL8WdboAS0e7wTjBVd7O0Tw-Xk1zlHAaymy5khbPtm7vNQi2i6OBIlbzgnFg1FJsxFbVO4FiW7aDJKYFa_Rh65Mv27QM0vUqO1AV4

I get this error:

stiv@gaidar:~/ffmpeg$ ./configure --enable-nonfree -–enable-cuda-sdk –enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64
Unknown option "-–enable-cuda-sdk".

How can I fix that? My hardware info:

you should use

--enable-cuda-sdk

instead of

-–enable-cuda-sdk

also

--enable-libnpp

You’re using illegal characters instead of minus(-) signs…

Yeah, thank you friend, copy-pasting from web site is dangerous because of these chars.

same here, dash-dash solved
