问题
Does anybody know how to add a C/C++ project nature to an Eclipse project through the UI ? I'm importing a project and working with legacy code that was originally started in Visual Studio 4 and I'd really like to be able to make as much use of Eclipse's helpers as possible.
回答1:
Assuming you've got the CDT plugin installed
Right-click on the project.
Select: New -> Other
Under C/C++, select "Convert to a C/C++ project"
回答2:
Create a new C project using the existing source code.
