clearmake –C sgipmake


Note: The distinctive features of clearmake, such as build auditing, derived object sharing, and build avoidance, are supported in dynamic views only. In addition, while parallel building is supported in ClearCase snapshot views, it is not supported in ClearCase LT.

The clearmake program has been designed for compatibility with existing make programs, minimizing the work necessary to switch to clearmake. There are many independently evolving variants of make, which provide different sets of extended features. clearmake does not support all features of all variants, and absolute compatibility is not guaranteed.

If your makefiles use only the common extensions, they will probably work with clearmake. If you must use features that clearmake does not support, consider using another make program in a clearaudit shell. This alternative provides build auditing (configuration records), but does not provide build avoidance (winkin).

Note: When building with configuration records, clearmake handles double-colon rules differently than other make programs. For details, see Building Software.


When you specify –C sgipmake, all the SGI smake features listed in the makefile_smake reference page are enabled, along with the following:

  • If no target description file is specified on the command line, search for Makefile before searching for makefile.
  • Undefined macros in build scripts are left unexpanded.
  • Undefined macros outside build scripts cause a fatal error.
  • One shell per build script. With –C sgismake, each command in the build script is executed in a separate shell.
