Building this package yields a bunch of errors on my machine, looks like it's trying to include gcc-14 includes (while cuda's nvcc should be using gcc-13?)

/usr/include/c++/14.1.1/x86_64-pc-linux-gnu/bits/c++config.h(827): error: user-defined literal operator not found 
    typedef __decltype(0.0bf16) __bfloat16_t;

libavutil, libavcodec, libavformat, libavfilter, libswresample are required to build nvencc.

All the required packages are install. Below are the flags used in the cxx_check for those libraries.

With CUDA 12.4 in Arch, updates are now running again. Real-world tests still need to be done.

Updates to NVEnc 7.42 are currently stalled, since NVEnc requires CUDA, CUDA requires at the moment gcc-12, but current NVEnc also requires ffmpeg and libhwy (highway) which is compiled with gcc-13, resulting in unresolved symbols.

One might be able to recompile highway and ffmpeg with gcc-12 and then update, but this cannot be detected/triggered automatically.

@ginger Indeed, confirmed. My guess it is the recent CUDA update. I have opened an issue at the github page https://github.com/rigaya/NVEnc/issues/533

Getting multiple instances of:

/usr/include/bits/floatn.h(86): error: invalid combination of type specifiers
  typedef __float128 _Float128;
                     ^


When compiling newest version on vanilla Arch. Can't find anything on how to fix anywhere (specific to this package, I mean).

npreining commented on 2023-03-19 00:15 (UTC)

@filipetaveiros you can add --cuda-path=/path/to/your/cuda to the configure call in PKGCONFIG

filipetaveiros commented on 2023-03-18 19:46 (UTC)

Same behavior that @teawrecks reported here. Installing on Manjaro Linux, the package looks for cuda on /usr/local/cuda. Tried to change PKGBUILD or other files o change that, but did not find where. Therefore, I created the symlink as suggested and it went well. Please, @npreining point us where to change the expected location for cuda.

logothete commented on 2022-11-14 18:35 (UTC)

@npreining that did the trick. Thanks!
