Tried to install in a VM running 16.04.1-Ubuntu, got a different error this time:

>>>sudo make
make -C .. lib
make[1]: Entering directory '/usr/local/liblinear-2.21'
g++ -Wall -Wconversion -O3 -fPIC -c -o linear.o linear.cpp

fi; \
g++ ${SHARED_LIB_FLAG} linear.o tron.o blas/blas.a -o liblinear.so.3
make[1]: Leaving directory '/usr/local/liblinear-2.21'

Any hints on how to solve this?

Thanks.

Thanks a lot for the answer, but if it is installed, why do I still get:

import liblinearutil as ll
ImportError: No module named 'liblinearutil'

and

>>> import liblinear
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/liblinear/__init__.py", line 35, in <module>
    raise Exception('LIBLINEAR library not found.')
Exception: LIBLINEAR library not found.

Thanks.
