Protobuf cannot find shared libraries

Question

I have installed protobuf by using following commands:

./configure make make check make install 

However when I run protoc I get following error:

protoc: error while loading shared libraries: libprotoc.so.8: cannot open shared object file: No such file or directory 

Answer 1

sudo ldconfig 

or

export LD_LIBRARY_PATH=/usr/local/lib 

should solve the problem.

Answer 2

You can also use

$ sudo ldconfig # refresh shared library cache. 

as stated at the installation page
