To create a new project, first visit a file that you want to include in that project. If you have a hierarchy of directories, first visit a file in the topmost directory. From this buffer, type M-x ede-new, or click on the ‘Create Project’ item in the ‘Development’ menu.
The ede-new command prompts for the type of project you
would like to create. Each project type has its own benefits or
language specific enhancements. Not all projects that EDE supports
also allow creating a new project. Projects such as
linux are designed to recognize existing projects only.
Project types such as ‘Make’ and ‘Automake’ do support
creating new project types with ede-new.
A subproject is merely a project in a subdirectory of another project. You can create a subproject by using the ede-new command (or the ‘Create Project’ menu item), while visiting a buffer in a subdirectory of the project root. This new project is automatically added to the parent project, and will be automatically loaded when EDE reads the parent project.
When using a project command that involves a makefile, EDE uses the top-most project's makefile as a starting place for the build. How the toplevel project handles subprojects in the build process is dependent on that project's type.
