-Compile whole groups of C/C++ files at once
-(C and C++ files are processed independently though).
-
-To enable globally::
-
- def options(opt):
- opt.load('compiler_cxx')
- def build(bld):
- bld.load('compiler_cxx unity')
-
-To enable for specific task generators only::
-
- def build(bld):
- bld(features='c cprogram unity', source='main.c', ...)
-
-The file order is often significant in such builds, so it can be
-necessary to adjust the order of source files and the batch sizes.
-To control the amount of files processed in a batch per target
-(the default is 50)::
-
- def build(bld):
- bld(features='c cprogram', unity_size=20)
