Use batch processing to add a pre-compiled header to the output c ++ file of protocbuffer

 

You can use the ProtocolBuffer compiler protoc. proto generation *. pb. cc C ++ code file. however, in projects with pre-compiled headers, you often need to manually add stdafx-like files. h. here we use batch processing to complete this process:

 

BuildProtoCC. bat

 

@ Echo off

 

Set protofile = % 1%. proto

Set output_cc = % 1%. pb. cc

 

"Protoc.exe" % protofile % -- cpp_out.

@ Echo use % protofile % to generate % output_cc %

 

If exist "pchheader.txt" goto merge precompiled headers else echo pchheader.txt NOT EXIST

 

: Merge pre-compiled Headers

@ Echo try to delete the previous intermediate file

Del *. pched

@ Echo merge the compilation and translation header file pchheader.txt to generate % output_cc %

Copy pchheader.txt + "% output_cc %" "% output_cc %. pched"/y

@ Echo wait until protoc.exe ends

@ Ping-n 2 127.1> nul

Echo file cleanup

Del "% output_cc %"

Ren "% output_cc %. pched" "% output_cc %"

 

 

 

This batch is used as follows:

 

Suppose you have a file named login. proto put together with the batch processing.

 

Put a pchheader.txt file in the same directory, and write # include "stdafx. h"

 

Call Batch Processing

 

Call BuildProtoCC. bat login

 

Note that login cannot contain a suffix.

 

Use protoc.exe to generate login. pb. cc and login. pb. h, and then use the batch file merging function to automatically merge pre-compilation headers.
