[SOLVED] Issue installing from source: CMake undefined references

1

I’ve been trying to build and install PyTorch master version from source, but at some point the installation fails with many “undefined reference” errors thrown by CMake. The first one is:

[ 97%] Linking CXX executable dlconvertor_test
CMakeFiles/broadcast_test.dir/broadcast_test.cpp.o: In function `barf(char const*, ...) [clone .constprop.40]':
broadcast_test.cpp:(.text+0xee): undefined reference to `std::runtime_error::runtime_error(char const*)'

I am following all the steps recommended in https://github.com/pytorch/pytorch, which are basically:

export CMAKE_PREFIX_PATH="~/.anaconda3/"
conda install numpy pyyaml mkl setuptools cmake cffi
conda install -c pytorch magma-cuda80
git clone --recursive https://github.com/pytorch/pytorch
cd pytorch
python setup.py install

Thank you in advance!

Just installed conda’s gcc and the issue is solved. Maybe this should be added to the list of required packages…
