comparison Makefile @ 287:4815ed0f21de prerelease

Makefile refactoring:
- avoids recursive call to build with/without main
- takes EXAMPLE parameter. Copies the examples/$(EXAMPLE) folder to projects/$(PROJECT) and $PROJECT defaults to exampleTestProject
- you can now `make run` (TODO: currently re-links, should instead run without linking)

 # set the project to be compiled by calling: make all PROJECT=<project_name>
 
 # if the PROJECT variable is not set, throw an error and exit
 # otherwise, we could have unexpected data loss when calling clean without it
 ifndef PROJECT
-  $(error PROJECT is not set)
+  ifndef EXAMPLE
+    $(error PROJECT or EXAMPLE should be set)
+  endif
 endif

 # This is a nasty kludge: we want to be able to optionally link in a default
 # main file if the user hasn't supplied one. We check for the presence of the main()
 # function, and conditionally call one of two recursive make targets depending on whether
 # we want to link in the default main file or not. The kludge is the mess of a shell script
 # line below. Surely there's a better way to do this?
