unsupported GNU version! gcc versions later than 5.3 are not supported

[tabsun]

I got this error when executing ./install.sh on my Ubuntu 16.04 with gcc-5.4. And it occurs at this position in install.sh line 129:

if [ -x "$path_to_nvcc" ] then echo "Found CUDA on your machine. Installing CUDA packages" cd ${THIS_DIR}/extra/cutorch && $PREFIX/bin/luarocks make rocks/cutorch-scm-1.rockspec || exit 1 cd ${THIS_DIR}/extra/cunn && $PREFIX/bin/luarocks make rocks/cunn-scm-1.rockspec || exit 1 fi

The log info looks like this: `echo "Building on $jopts cores" cmake -E make_directory build && cd build && cmake .. -DLUALIB= -DCMAKE_CXX_FLAGS=${CMAKE_CXX_FLAGS} -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH="/home/tabsun/proj/torch/install/bin/.." -DCMAKE_INSTALL_PREFIX="/home/tabsun/proj/torch/install/lib/luarocks/rocks/cutorch/scm-1" && make -j$jopts install

I have tried to comment the GNU version detection in /usr/local/cuda/include/host_config.h, it failed. Also I checked the nvidia website, it says cuda 8.0 supports gcc 5.4. Expanded developer platform support including Microsoft Visual Studio 2015 (updates 2 and 3) and GCC 5.4 (Ubuntu 16.04).

So why I got this error? I also installed tensorflow on this machine and it works well so there should be no problem with cuda's installation, I think. Any idea about this situation is REALLY APPRECIATED!

Way around this

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9 g++-4.9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9

@ibmua solved my problem

[xiaofanglegoc]

my cuda is 8 which is not compatible with caffe

@ibmua I tried your suggestion on a Google Colab notebook and I'm getting the error below

! add-apt-repository -y ppa:ubuntu-toolchain-r/test ! apt-get update ! apt-get install gcc-4.9 g++-4.9

you could try manually installing gcc using these instructions https://gist.github.com/jtilly/2827af06e331e8e6b53c

@ibmua I tried your approach, however, I can't install g++-4.9 Package g++-4.9 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

E: Package 'g++-4.9' has no installation candidate

Srsly, just get PyTorch, Torch something of a discontinued project.

[dufferzafar]

@rraallvv I have this error too (on Google Colab!) Did you find a fix?

[rraallvv]

@dufferzafar there is a notebook here that might be of some help, the related discussion is here. Cheers!

[markroxor]

Use cmake -DCMAKE_C_COMPILER=gcc-4.9 -DCMAKE_CXX_COMPILER=g++-4.9 .. before cmake to specify gcc/g++ compiler. Only this solution worked for me.

[binary-person]

Just install 4.8 and make it default. Besides, gcc version 4.9 is officially not supported Google Colab:

!sudo update-alternatives --remove-all gcc 
!sudo update-alternatives --remove-all g++

!sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
!sudo apt-get update

!sudo apt-get install gcc-4.8 g++-4.8

!sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50
!sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 50

!sudo update-alternatives --install /usr/bin/cc cc /usr/bin/gcc 50
!sudo update-alternatives --set cc /usr/bin/gcc

!sudo update-alternatives --install /usr/bin/c++ c++ /usr/bin/g++ 50
!sudo update-alternatives --set c++ /usr/bin/g++

!sudo update-alternatives --config gcc
!sudo update-alternatives --config g++

Normal Ubuntu Machine:

sudo update-alternatives --remove-all gcc 
sudo update-alternatives --remove-all g++

sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
sudo apt-get update

sudo apt-get install gcc-4.8 g++-4.8

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 50

sudo update-alternatives --install /usr/bin/cc cc /usr/bin/gcc 50
sudo update-alternatives --set cc /usr/bin/gcc

sudo update-alternatives --install /usr/bin/c++ c++ /usr/bin/g++ 50
sudo update-alternatives --set c++ /usr/bin/g++

sudo update-alternatives --config gcc
sudo update-alternatives --config g++

If you want to completely remove the new version, which I highly don't recommend, because it uninstalls everything that requires gcc to run including your CUDA drivers Google Colab:

!sudo apt-get remove gcc g++ -y
!sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
!sudo apt-get update
!sudo apt-get install gcc-4.8 -y
!sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50

Normal Ubuntu Machine:

sudo apt-get remove gcc g++ -y
sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
sudo apt-get update
sudo apt-get install gcc-4.8 -y
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50
