Linking

Though linking occurs automatically, the options in this category allow you to direct input and output to the linker, controlling how the linker processes your object files.

Table 1. Linking options
Option name	Equivalent pragma name	Description
-b	None.	Sets special linker processing options. This option can be repeated.
-bmaxdata	None.	Sets the maximum size of the area shared by the static data (both initialized and uninitialized) and the heap.
-brtl	None.	Controls runtime linking for the output file.
-qcrt	None.	Specifies whether system startup files are to be linked.
-e	None.	When used together with the -qmkshrobj or -G option, specifies an entry point for a shared object.
-f	None.	Names a file that stores a list of object files for the compiler to pass to the linker.
-L	None.	Searches the directory path for library files specified by the -l option.
-l	None.	Searches for the specified library file. For static and dynamic linking, the linker searches for libkey.a. For runtime linking with the -brtl option, the linker searches for libkey.so, and then libkey.a if libkey.so is not found.
-qlib	None.	Specifies whether standard system libraries and XL C libraries are to be linked.
-Z	None.	Specifies a prefix for the library search path to be used by the linker.
