@PROCESS
None.
Purpose
Creates a shared object from generated object files.
Use this option, together with the related options described later in this topic, instead of calling the linker directly to create a shared object. The advantage of using this option is that it is compatible with -qipa link-time optimizations (such as those performed at -O5).
Defaults
By default, the output object is linked with the runtime libraries and startup routines to create an executable file.
Usage
When the -qmkshrobj option is specified, the driver program starts the CreateExportList utility to create an export list from the input list of object files.
The compiler automatically exports all global symbols
from the shared object unless you specify which symbols to export
by using -bE:, -bexport:,
or -bnoexpall. You can also prevent weak symbols from being exported
by using the -qnoweakexp option. 
Symbols that have the hidden or internal visibility attribute
are not exported.
Specifying -qmkshrobj implies -qpic.
You can also use the following related options with -qmkshrobj:
- -o shared_file
- The name of the file that holds the shared file information. The default is shr.o.
- -qexpfile=filename
- Saves all exported symbols in filename.
- -e name
- Sets the entry name for the shared executable to name.
- -q[no]weakexp
- Specifies whether symbols marked as weak are to be included in the export list. If you do not explicitly set this option, the default is -qweakexp (global weak symbols are exported).
