-o
Purpose
Specifies a name for the output object, assembler, executable, or preprocessed file.
Syntax
Defaults
See Types of output files for the default file names and suffixes produced by different phases of compilation.
Parameters
- path
- When you are using the option to compile from source files, path can be
the name of a file a relative or absolute path name. When you are using the option to link from
object files, path must be a file name.
You cannot specify a file name with a C or C++ source file suffix (.C, .c, or .cpp), such as
myprog.c; this results in an error and neither the compiler nor the linker is invoked.
Usage
If you use the -c option with -o , you can compile only one source file at a time. In this case, if more than one source file name is specified, the compiler issues a warning message and ignores -o.
The -E, and -fsyntax-only options override the -o option.
Predefined macros
None.
Examples
To compile
myprogram.c so that the resulting executable is called
myaccount
, enter:
ibm-clang myprogram.c -o myaccountTo compile
test.c to an object file only and name the object file
new.o, enter:
ibm-clang test.c -c -o new.o
