Use response files to specify options used during particular compilations for particular projects, and to save this information in individual files. Response files are invoked as an option on the command line. Options specified in a response file are inserted in the command line at the point where the response file is invoked.
Response files are used to decrease the time spent entering command-line options, and to ensure consistency by automating command-line entries. Use individual response files to maintain options for specific projects; in this way you avoid editing the configuration file when changing projects.
You can place any number of options or filenames on a line in the response file. Several response files can be referenced in the same command line.
The syntax for using response files is as follows :
IA-32 applications:
prompt>ifc @response_filename
prompt>ifc @response_filename1 @response_filename2
Itanium(TM)-based applications:
prompt>efc @response_filename
prompt>efc @response_filename1 @response_filename2
Note
An "at" sign (@) must precede the name of the response file on the command line.
