When compiling a Cython file using following command, I encountered the error 'error while loading shared libraries: libmpfr.so.4'. I link libmpfr.so.4 to libmpfr.so.6 as shown here. After the link, I got the error 'bits/libc-header-start.h: No such file or directory'.

from distutils.core import setup from Cython.Build import cythonize import numpy setup( ext_modules = cythonize("_online_lda.pyx"), include_dirs = [numpy.get_include()] ) Then I link libmpfr.so.4 to libmpfr.so.6 using following command.
sudo ln -s /usr/lib/x86_64-linux-gnu/libmpfr.so.6 /usr/lib/x86_64-linux-gnu/libmpfr.so.4 Running the python setup.py again gives following error message.
