Missing input file with protoc in protocol buffer

Question

I currently have a file called addressbook.proto in next to my protoc.exe. I am having difficulty generating the .h and the .cc file. Here is what I am doing

protoc --cpp_out=c:\addressbook.proto

However I get the following response

Missing input file.

Any suggestions on what I might be doing wrong ?

Answer 1

The -cpp_out tag specifies the output directory for generated c source code.

I would suggest trying (if proto is actually stored under the c: directory c:\addressbook.proto)

protoc c:\addressbook.proto --cpp_out=./

or

protoc addressbook.proto --cpp_out=./
