    What is the purpose of NVCC?

    The purpose of nvcc, the CUDA compiler driver, is to hide the complex details of CUDA compilation directly from developers. It accepts a number of traditional compilation options such as defining macros and even including library paths and controlling the compilation process.

    Solution: permanently change PATH and LD_LIBRARY_PATH changes with a .bashrc file

    1. Create a bashrc file in the ~/home directory

  • Enter file:
  • 3. Scroll down and enter the PATHS of the .bashrc file:

    Configuring the #CUDA environmentExport PATH =/usr/local/cuda-10.0/bin$PATH:+:$PATHexport LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64$LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH
    $nvcc -V

    For our RHEL7 functions, when using cuda 10.0/1/2, nvcc screams cuda syntax errors in header files. What always turned out on closer inspection are, for example, declarations (from cuComplex.h):

    if (v == 0.0f)

    Of course, this is also a syntax error bka! I tried with nvcc both systems gcc 4.8.5 gcc7 with the same strange result. Test case (xx.cu):

    __host__ __device__float test_me (float v)   if (v == 0.0f) // write this 0.0f here and below.            return v 7 . 42;        return v 1. v;

    nvcc error

    float test_me(float v){if (v == (nan.0F)) // WTF provided 'nan' from    v (space) (42) return;return to * to;

    Recompile FFMPEG With Cuvid And Nvcc Problem

    Sorry I can enjoy successfully compiled opencv (using Dlandons Docker) 1 . nvidia-smi shows the stock driver (440.59) to build. CUDA 10.2 seems to install fine (although

    “`nvcc –version“` appears as a command and was never found? Does it mean failure? Can’t find errors in the logs?

    What I really need are some guides on how to uninstall FFMPEG and recompile it with cuvid per cuda support (because I can’t find a better guide)Amenities)

    However, if someone can direct me to the right support, that would be great

    :)

    Re: Problem Recompiling FFMPEG To Cuvid And Nvcc

    I found this guide so I will try here (my issue is variable mapping to what Zoneminder is using)

    Recompile ffmpeg

    In order to inspire ffmpeg to use the GPU codec provided by CUDA, ffmpeg needs to be recompiled so that it can view CUDA via dynamic links

    Start by compiling or installing the nv-codec-headers

    library

    Code: select all

    git https://git clone.videolan.org/git/ffmpeg/nv-codec-headers.gitdo PREFIX="/home/local/ffmpeg_build" BINDDIR="/home/local/bin"make install PREFIX="/home/local/ffmpeg_build" BINDDIR="/home/local/bin" 

    Enter the directory /home/local/ffmepg_sources/ffmpeg-3.3.8/ to restart compiling and installing ffmpeg

    Note the nature of the difference between the Configure-Acquiring parameter and the previous Configure-Control

    parameter

    Code: select all

    PATH="/home/local/ffmpeg_sources/bin:$PATH" PKG_CONFIG_PATH="/home/local/ffmpeg_sources/ffmpeg_build/lib/pkgconfig" ./configure --prefix="/home/local/ ffmpeg_sources /ffmpeg_build" --pkg-config-flags="--static" --extra-cflags="-I /home/local/ffmpeg_sources/ffmpeg_build/include -I/usr/local/cuda/include" --extra - ldflags="-L /home/local/ffmpeg_sources/ffmpeg_build/lib -L/usr/local/cuda/lib64" --extra-libs=-lpthread --extra-libs=-lm --bindir="$HOME / bin" --enable-gpl --enable-libfdk_aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable -nonfree --enable-libfreetype --enable-cuda --enable-cuvid --enable-nvenc --enable-libnpp

    Check installation

    After reinstalling ffmpeg, use the ffmpeg-hwaccels influence to see supported hardware speed options

    Re: Recompile FFMPEG If You Have Problems With Cuvid And Nvcc

    nvcc error

    I can’t believe there was no script or manual for this? The Zoneminder documentation also states “Only if you have a GPU and FFMPEG is compiled to support it.”
