I am trying to install caffe by building it from source

After issuing the following command from the caffe root directory

$ make all -j4

I am getting an error

...

LD -o .build_release/lib/libcaffe.so.1.0.0

I have looked at all the issues in the source Github repository but couldn't find anything useful.

The issue is resolved, I had to make the following changes in Makefile.config file

From

PYTHON_LIBRARIES := boost_python3 python3.6
PYTHON_INCLUDE := /usr/include/python3.6 \
/usr/lib/python3.6/dist-packages/numpy/core/include

To

PYTHON_LIBRARIES := boost_python3 python3.6m
PYTHON_INCLUDE := /usr/include/python3.6m \
/usr/lib/python3.6/dist-packages/numpy/core/include

Therefore that your error states cannot find -lpython3.6 you are missing the libpython3.6.so on your system.

Try to:
sudo apt-get install libpython3.6-dev
