Description

I'm trying to build Mxnet from source using this guide https://mxnet.apache.org/get_started/ubuntu_setup and at running cmake .. command the build is stuck at infinite loop.

Error Message

-- Configuring done

You have changed variables that require your cache to be deleted.
Configure will be re-run and you may have to reset some variables.
The following variables have changed:
CMAKE_CUDA_COMPILER= /usr/local/bin/nvcc
CMAKE_CUDA_COMPILER= /usr/local/bin/nvcc

Last lines look relevant.
And than the process repeats itself indefinitely:

-- The C compiler identification is GNU 8.3.0
-- The CXX compiler identification is GNU 8.3.0
-- Check for working C compiler: /usr/local/bin/cc
-- Check for working C compiler: /usr/local/bin/cc -- works
...

To Reproduce

Follow https://mxnet.apache.org/get_started/ubuntu_setup

Steps to reproduce

(Paste the commands you ran that produced the error.)

1.Install prerequisites
2. Clone repo and copy config

git clone --recursive https://github.com/apache/incubator-mxnet.git mxnet
cd mxnet
cp config/linux_gpu.cmake config.cmake  # or config/linux_gpu.cmake for build with CUDA

The only change in config I did -- I disabled OpenCV.

  1. Run config:
rm -rf build
mkdir -p build && cd build
cmake ..

What have you tried to solve it?

  1. I uncommented CMAKE_CUDA_COMPILER line and removed cache from there
    set(CMAKE_CUDA_COMPILER "nvcc" STRING "Cuda compiler (nvcc)")

  2. And it's building as it should.

We recently added a convenience functionality in #17293 that attempts to do the right thing even if cuda is not installed correctly. Seems that leads to an infinite loop unfortunately. It needs to be fixed. Thanks for reporting the issue.

You didn't install cuda correctly. In particular you didn't do https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#mandatory-post
nvcc is not on your PATH.

As a quick workaround, you can run with CUDACXX=/usr/local/cuda/nvcc cmake

I have nvcc in my $PATH as follows:

➜  build git:(master) echo $PATH
/home/cepera/miniconda3/condabin:/home/cepera/bin:/home/cepera/.nvm/versions/node/v12.3.1/bin:
/home/cepera/.local/bin:/home/cepera/bin:/usr/local/sbin:/usr/local/bin:
/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:
/home/cepera/.fzf/bin:/usr/local/cuda-10.1/bin
➜  build git:(master) which nvcc            
/usr/local/bin/nvcc

Also, if I set CUDACXX as you suggested it seems like Cmake ignores it and still guesses different path and, unfortunately, still loops:

<truncated>

Update: if I set CUDACXX=/usr/local/cuda/bin/nvcc (exactly as Cmake "guesses") then it configures successfully.

Thanks for the update @cepera-ang. Could you try changing

if (NOT CMAKE_CUDA_COMPILER_LOADED AND UNIX AND EXISTS "/usr/local/cuda/bin/nvcc")

to

if (NOT CMAKE_CUDA_COMPILER AND UNIX AND EXISTS "/usr/local/cuda/bin/nvcc")

Seems in #17293 we used the wrong variable, as per https://gitlab.kitware.com/cmake/cmake/issues/19013

The search behavio for CUDAToolkit is specified in https://gitlab.kitware.com/cmake/cmake/-/blob/master/Modules/FindCUDAToolkit.cmake In general, it relies on the location of nvcc, so it may get confused by /usr/local/bin/nvcc. It's a strange location to have nvcc at. Did you install the cuda libraries also to /usr/local? Usually they are at /usr/local/cuda.

The infinite loop issue is a separate issue and should be fixed by #17773.

It is indeed strange location for nvcc and it happens to be some misconfiguration on my machine. /usr/local/bin/nvcc is a symbolic link to ccache and removing it solves the problem (tried with changes in #17773).

Thanks for you time @leezu! It is rare to get this kind of fast and thorough response with open source project and I highly appreciate it.
