A-1.0 Sample makefile
The makefile shown in Figure 8, below, is for use with both legacy and Legion-aware programs that will be executed with either legion_run or legion_run_multi. In the sample below we started with a legacy C++ code, gnomad.c, and modified it to use the Legion I/O libraries. This allows the application to manipulate context space directly rather than copying a lot of files around. A copy of the original program was kept in the file gnomad_orig.c.
The makefile has targets for five platforms: intel, sgi, solaris, ibm, and alpha_linux. The make targets are slightly different for each machine because the c++/g++ compiler sits in different places and may not be found by the default search path. Therefore, we hard-wired each target to known paths. If these paths don't work for you, log on to a compilation box and get the path directly.
Each make target uses legion_make to start a make on the desired platform. The make target then compiles and registers both the pure legacy code and the Legion-aware code. After each code is compiled, the resulting binary is registered in Legion space in the desired directory, in this case in /home/grimshaw.
