Porting From Specific UNIX Systems
Open System Services Porting Guide—520573-006

Development Tools
You should perform your program analysis before porting to the OSS environment.
Therefore, these tools are not provided with the OSS environment.
Program Management Tools
The following program management tools might be available on your UNIX
workstation:
•
make is one of the most important utilities that comes with UNIX systems. It tracks
dependencies between modules of a program and builds an executable file using
rules in the make file.
More information about using make is available in the make(1) online reference
page; make is also available in the OSS environment.
If you perform your compilations on the workstation using make, then you can
perform your compilations in the OSS environment using make; make files should
be relatively easy to port to the OSS environment.
•
imake is a publicly available program that uses the dependencies in your source
code to build a make file from specified rules. You might have to edit the make file
slightly to suit your programming needs, but imake does a large part of the
building job for you.
More information about using imake is available in the imake(1) online reference
page; imake is not available in the OSS environment.
•
The Source Code Control System (SCCS) is used to manage source code. SCCS
was developed by AT&T and comes with SVR3 and SVR4 UNIX systems and with
SunOS systems.
SCCS is not provided as part of the OSS environment.
•
The Revision Control System (RCS) is used to manage source code. RCS was
created at Purdue University; it is available from the public domain, distributed by
the Free Software Foundation, Inc. under the GNU license. It is also available on
some SunOS systems.
RCS is not provided as part of the OSS environment but ported versions are
available from third-party sources.
The search path for make files does not include SCCS or RCS in the OSS
environment.
C Source Code Utilities
The following C source code utilities might be available on your UNIX workstation:
•
m4 is a general-purpose macro preprocessor for C programs.
•
cb is a C program beautifier that helps produce more readable C code.
