Starting a parallel build

Follow the steps mentioned in this content to start a parallel build.

To start a parallel build:

1. Set the CCASE_HOST_TYPE variable. The value of this variable determines which build hosts file that clearmake looks for in your home directory:

   Value

   Build hosts file that clearmake looks for.

   day

   .bldhost.day

   night

   .bldhost.night

2. Start clearmake. To enable parallel building, use the -J command-line option or set the CCASE_CONC environment variable. To specify a build hosts file, use the -B option. To have clearmake choose a build hosts file, do not use -B.

   For example, to specify a build hosts file and start a build that builds up to five targets concurrently, use one of the following methods:

   % clearmake -J 5 -B ~/.bldhost.day my_target % setenv CCASE_CONC 5 % clearmake-B ~/.bldhost.day my_target % setenv CCASE_HOST_TYPE day % clearmake-J 5 my_target % setenv CCASE_CONC 5 % setenv CCASE_HOST_TYPE day % clearmake my_target
