Hi All,

This may be a silly question but I'm unable to compile my C++ code with protobuf on ubuntu.

I've installed it in /usr/local/ and while running below command

g++ main.cpp -L/usr/local/lib -l lprotobuf

I get this error.

/usr/bin/ld: cannot find -llprotobuf
collect2: error: ld returned 1 exit status

Can someone help me in this regard ?

How about this

g++ main.cpp -L/usr/local/lib -lprotobuf

You will also have to include your protobuf generated code from address_book.pb.cc (generated by protoc).
