-c
Purpose
Instructs the compiler to compile or assemble the source files only but do not link. With this option, the output is a .o file for each source file.
Syntax
Defaults
By default, the compiler invokes the linker to link object files into a final executable.
Usage
When this option is in effect, the compiler creates an output object file, file_name.o, for each valid source file, such as file_name.c, file_name.i, file_name.C, file_name.cpp, or file_name.s. You can use the -o option to provide an explicit name for the object file.
The -c option is overridden if the -E or -fsyntax-only option is specified.
Predefined macros
None.
Examples
To compile myprogram.c to produce an object file myprogram.o,
but no executable file, enter the command:
ibm-clang myprogram.c -cTo compile myprogram.c to produce the object file new.o and no
executable file, enter the command:
ibm-clang myprogram.c -c -o new.o
