NAME
alibcompress - merge delta sublibraries in a sublibrary
SYNOPSIS
alibcompress [-hv] [F|W] [Sublibrary]
DESCRIPTION
Use the alibcompress command to eliminate each delta sublibrary in the specified sublibrary, reducing the amount of space occupied by the sublibrary and speeding up compile and bind operations which reference the sublibrary.
This operation is automatically done to all sublibraries in a project when converting it to a baseline project using aprojbaseline or powerada.
Exclusive write access is required to the sublibrary in order to perform this operation.
OPTIONS
- -h
- Help: display brief usage and version information.
- -v
- Verbose: display progress messages
- -F
- Force: ignore read-locks on the sublibrary (default: fail).
- -W
- Wait to get write-lock on the sublibrary( default: fail)
- The -F and -W options are mutually exclusive.
PARAMETERS
- Sublibrary...
- Specifies the name of a PowerAda sublibrary (default:
adalib)
