Porting Instructions

To port dmake to a new environment it is useful to understand the source hierarchy. Once you are familiar with the organization of the source files then follow the following steps.

The sysvr3 version is the base version, all dmake versions must provide the equivalent of the functions defined in the sysvr3 directory, and MUST provide the same semantics (MSDOS archive lib searches are an exception since we cannot easily search libraries for timestamps in MSDOS.

Create a new directory for the version you will be making at the level that is appropriate. If it is a new OS then add the dir at the top level, if it is a new version of UNIX then add it below the unix directory.
Copy the files from the unix and unix/sysvr3 directories to the new dir. (Or from any other directory sub-tree that is more appropriate)
Not all OS/OSRELEASE combinations are compatible so in order to make dmake on each, the particular directory may contain C-source for functions present in the SVID SysV R3 distribution which are used by dmake but are not supplied by the C-library in the target system. For example the bsd43 directory contains source for tempnam.c since it is not provided with the BSD C-library. Before writing a new version of the source file check the other directories to see if one already exists.
Under some systems the standard include files may be missing or incorrect. eg. under BSD stdarg.h and string.h. If this is the case you should create the proper .h file in the proper directory. This works as expected as the compile line includes the flag -Idir where dir is the configuration dir, (bsd43 for example) and any standard include files will be searched for in dir before the compiler looks in the normal places (if you have a sane compiler :-).
Modify dmake.sh to contain the appropriate C compiler flags and link command and to include any specific C files that you have had to add for this version of dmake, and run the result through the shell. (make the same changes to config.mk so that once you have a working copy of dmake you can use it to bring itself up to date)
Send us the changes so that they can be incorporated into future distributions.
This should be all that you require to create a new version of dmake. If you have any questions send e-mail.
