-o
Category
Pragma equivalent
None.
Purpose
Specifies a name for the output object, assembler, executable, or preprocessed file.
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. path can
be 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 only compile one source file at a time. In this case, if more than one source file name is listed in the compiler invocation, the compiler issues a warning message and ignores -o.
The -P and -fsyntax-only (-qsyntaxonly) options override the -o option.
Predefined macros
None.
Examples
To compile myprogram.c so
that the resulting executable is called myaccount,
enter:
xlc myprogram.c -o myaccountTo
compile test.c to an object file only and name the
object file new.o, enter:
xlc test.c -c -o new.oRelated information
