cuda92,pytorch 0.4 make error

[jhxu-org]

my server is ubuntu 16.04,torch 0.4 When I execute the make all command,i get the error :

On Ubuntu 18.04, I first needed to install gcc and g++ 4.9 as explained here: https://stackoverflow.com/questions/48398475/fail-to-install-gcc-4-9-in-ubuntu17-04 (gcc/g++ 5 and 6 were producing the same error for me as the one you have) Then, you'll need to link these new gcc and g++ to your cuda:

$ sudo ln -s /usr/bin/gcc-4.9 /usr/local/cuda/bin/gcc
$ sudo ln -s /usr/bin/g++-4.9 /usr/local/cuda/bin/g++

and you need to run cmake in the following way:

cmake -DCMAKE_C_COMPILER=gcc-4.9 -DCMAKE_CXX_COMPILER=g++-4.9 ../

@grig-guz
i did as you said,but the problem still exists. by the way, i use gtx2080ti.
