Comienze la construcción. Automaticamente esto compilará el toolchain, realizará una compilacion-cruzada sobre las fuentes, empaquetará los paquetes, y finalmente generará una imagen lista para ser flasheada.

Note que instalando en el contexto de los scripts ./scripts/feeds significa "haciendo los paquetes disponibles en make menuconfig " mas que realmente instalarlos o compilarlos.

select your target before issuing defconfig will produce a general purpose configuration of the build system including a check of dependencies and prerequisites for the build environment etc

Menuconfig has a TUI, which handles the selection of the target, packages to be compiled, packages to be included in the firmware file, some kernel options etc.

This will update the dependencies of your existing configuration automatically and you can now proceed to build your updated images.

It has from the beginning on been the intention, with the development of 'menuconfig', to create a simple yet powerful environment for the configuration of individual OpenWrt images. Menuconfig is more or less self-explanatory, and even the most specialized configuration needs can be solved with its help. Depending on the the particular target platform, package requirements and kernel module needs, the standard process of configuration will include modifying:

Target system is selected from the extensive list of supported platforms, with the numerous target profiles – ranging from specific devices to generic profiles, all depending on the particular device at hand. Package selection has the option of either 'selecting all package', which might be un-practical in certain situation, or relying on the default set of packages will be adequate or make an individual selection. It is here needed to mention that some package combinations might break the build process, so it can take some experimentation before the expected result is reached. Added to this, the OpenWrt developers are themselves only maintaining a smaller set of packages – which includes all default packages – but, the feeds-script makes it very simple to handle a locally maintained set of packages and integrate them in the build-process.

The final step before the process of compiling the intended image(s) is to exit 'menuconfig' – this also includes the option to save a specific configuration or load an already existing, and pre-configured, version.

The 'Build system settings' include some efficient options for changing package locations which makes it easy to handle a local package set:

In the case of the first option, you simply enter a full URL to the web or ftp server on which the package sources are hosted. Download folder would in the same way be the path to a local folder on the build system (or network). If you have a web/ftp-server hosting the tarballs, the OpenWrt build system will try this one before trying to download from the location(s) mentioned in the Makefiles. Similar if a local 'download folder', residing on the build system, has been specified.

The 'Kernel modules' option is required if you need specific (non-standard) drivers and so forth – this would typically be things like modules for USB or particular network interface drivers etc.

In many cases, you may want to have a custom image that has been pre-configured. If so, place your custom files in

For example, let's say that you want an image with a pre-configured /etc/config/firewall. then place your modified firewall config in here: E.g. if your <buildroot dir> is /openwrt/trunk and you want some files to be copied into firmware image's /etc/config directory, the correct place to put them is /openwrt/trunk/files/etc/config.
