Output control

The options in this category control the type of file output the compiler produces, as well as the locations of the output.

These are the basic options that determine the compiler components that will be invoked, the preprocessing, compilation, and linking steps that will (or will not) be taken, and the kind of output to be generated.

Table 1. Compiler output options
Option name	@PROCESS directive	Description
-c	None.	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.
-d	None.	Causes preprocessed source files that are produced by cpp to be kept rather than deleted.
-E	None	Preprocesses the source files named in the compiler invocation, without compiling. When preprocessing is not enabled, this option has no effect. To enable preprocessing, you can specify the -qpreprocess option.
-G	None.	Generates a shared object enabled for runtime linking.
-MMD	None.	Produces a dependency output file containing targets suitable for inclusion in a description file for the make command. -MMD is the short form of -qmakedep.
-MF	None.	Specifies the name or location for the dependency output files that are generated by the -qmakedep or -MMD option.
-MT	None.	Specifies the target name of the object file in the make rule in the dependency output file that is generated by the -qmakedep or -MMD option.
-o	None.	Specifies a name for the output object, assembler, or executable file.
-qmakedep	None.	Produces a dependency output file containing targets suitable for inclusion in a description file for the make command. -qmakedep is the long form of -MMD.
-qmkshrobj	None.	Creates a shared object from generated object files.
-qmoddir	None.	Specifies the location for any module (.mod) or submodule (.smod) files that the compiler writes.
-qtimestamps	None.	Controls whether or not implicit time stamps are inserted into an object file.
-S	None.	Generates an assembler language file for each source file.
