This post covers essentially the same question:http://forums.arm.co...ram-on-eclipse/Just to be clear, I assume that even though you are building on Windows, you are generating an application for Linux (the DS-5 GCC only supports generating Linux applications and libraries).For a Linux application, you can select either of the following from the New Project -> C Project dialog:Project Type = Executable / Empty Project, Toolchain = DS-5 GCCProject Type = Makefile project / Empty Project, Toolchain = DS-5 GCCThe former creates a CDT managed project, where Eclipse/CDT works out what to build and how to build it. The later uses a makefile, and is useful if you want the ability to build your project outside of Eclipse. Note that the makefile project does not generate a makefile by default, but can be configured to do so with some additional steps:Right-click on your project in the Project Explorer viewand click on Properties in the menu. In the Properties dialog, select the C/C++Build tab, and then ensure the "Generate Makefiles automatically" isenabled. Then click OK to close the dialog. Now when you build, the makefile isgenerated and the build should complete.
