This information is provided in the -hope that it makes it easier to install and recompile dmake in a OS/2 -environment. - -Notes on the OS/2 implementation of dmake: -========================================== - -As shipped the DOS versions of dmake will run under OS/2 protected mode. -However, support for a full OS/2 version is also provided. The OS/2 version -will run in parallel under OS/2. - -Bootstrapping the binary: -------------------------- - A make.cmd file is provided to bootstrap the binary. The file contains - several targets for bootstrapping. Invoking the batch file with no - arguments lists the possibilities shown below. - - INDEX: You must specify one of: - ibm - IBM C2 compile. - - The only supported compiler under OS/2 is the Visual Age ICC compiler. - I have tested the build using this compiler. The resulting binary - performs proper directory caching and file-name case mapping for cached - directories and is capable of parallel target builds. The only known - limitation of the OS/2 implementation is the treatment of library time - stamps. Libraries do not have time stamps on members and the timestamp - of the library is used instead. - - -OS/2 Specifics --------------- - - There is a small number of OS/2 specific features that need to be - stated. - - 1. The environment variables TMP as well as TMPDIR are checked for the - location of the directory where dmake should place any temporary files. - TMPDIR is checked before TMP. - - 2. Appropriate limits are setup for MAXPROCESSES and buffer sizes etc. - See output of 'dmake -V'. - - 3. By default dmake will look for the startup.mk file in the path: - - $(ROOTDIR)/dmake/startup/startup.mk - - This is more in keeping with OS/2 philosophy. You may still rename - and put it anywhere else you like by defining the MAKESTARTUP - environment variable. - - 4. Swapping the dmake binary to disk is not supported under OS/2. - - -Other notes: ------------- - dmake does not care if you are running cmd.exe or some other command - interpretter, you must however specify the proper values of the environment - variables SHELL, SHELLFLAGS, GROUPSHELL, and GROUPFLAGS in order for things - to work correctly. Read the man page first. - - Group recipes under OS/2 that use cmd.exe as the command interpretter - require you to set the GROUPSUFFIX macro. - - As shipped the startup.mk files try to figure out what - command interpretter you are using and set things up appropriately. - Two command interpretters are supported in the shipped startup.mk file, - cmd.exe (via COMSPEC), and the MKS Korn shell. - - dmake does not contain any builtin commands. It gets all commands it - executes from an external file system. It is therefore most useful if it - is used in conjunction with an environment similar to that provided by - the MKS Tool kit, or equivalent. - - dmake now supports the MKS argument passing conventions. The facility is - enabled by setting .MKSARGS:=1 and is set by default in the startup.mk file - if an MKS Korn shell is detected as being the active command interpretter. |
