Compiling Instructions for Alias OpenModel and OpenAlias

In the distribution of Alias Studio or Alias PowerAnimator under /usr/aw/alias, there is a directory called ODS (an abbreviation for Open Digital Studio). Below this directory are three directories relevant to the Alias API. These directories are:

• OpenModel - examples, compiled examples (SGI only), and libraries specific to Alias OpenModel
• OpenAlias - examples and compiled examples (plug-ins) specific to OpenAlias (an external library is not required)
• Common - examples and include files common to Alias OpenModel and OpenAlias

Compiling code for either Alias OpenModel or OpenAlias is straightforward and the process can easily be understood when reading the example Makefiles in /usr/aw/alias/ODS/OpenModel (or ODS/OpenAlias). However below are detailed the important concepts.

When building Alias API programs, ensure that the include path for the compiler includes the path (in the CFLAGS variable):

-I$(ALIAS_LOCATION)/ODS/Common/include

where $(ALIAS_LOCATION) is usually /usr/aw/alias. The definition of ALIAS_LOCATION at the top of the example Makefile is only necessary if you need to override the value in the environment variable.
