Protobuf cannot find shared libraries

Question

I installed protobuf using the following commands:

./configure make make check make install 

However, when I run protoc , I get the 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

This problem can be solved by following these steps:

• vim / etc / ld.so.conf
• / usr / local / lib (add it to .conf)

Answer 3

This problem can be solved by following these steps:

 sudo make uninstall sudo make distclean sudo make clean ./configure --prefix=/usr 

This clears the current installation and installs protobuf in / usr. Run ldconfig to update ld.so.cache, making sure / usr / local / lib is specified in /etc/ld.so.conf. i.e. Change /etc/ld.so.conf and add / usr / local / lib to it and run ldconfig

Answer 4

You can also use $ sudo ldconfig # refresh shared library cache. as indicated on the installation page
