The new skeleton of the manual as it has been thought: 1. About Buildroot: Presentation of Buildroot 2. Starting up: Everything to quickly and easily start working with Buildroot 3. Working with Buildroot Basics to make your work fitting your needs 4. Troubleshooting 5. Going further in Buildroot's innards Explaination of how buildroot is organised, how it works, etc 6. Developer Guidelines 7. Getting involved 8. Contibuting to Buildroot 9. Legal notice 10. Appendix It is easy to distinguish two parts in this plan: - Sections 1 to 4 mainly address people starting with Buildroot - Sections 5 to 10 are more focused on how to develop Buildroot itself Most of the existing sections have just been moved in the hierarchy, few were split and dispatch in, what i think was the relevant section, and numerous others have been created.

To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) Use your shiny new root filesystem. Depending on which sort of root filesystem you selected, you may want to loop mount it, chroot into it, nfs mount it on your target device, burn it to flash, or whatever is appropriate for your target system. You do not need to be root to build or run buildroot. Have fun! Offline build: ============== In order to do an offline-build (not connected to the net), fetch all selected source by issuing a $ make source before you disconnect. If your build-host is never connected, then you have to copy buildroot and your toplevel .config to a machine that has an internet-connection and issue "make source" there, then copy the content of your dl/ dir to the build-host. Building out-of-tree: ===================== Buildroot supports building out of tree with a syntax similar to the Linux kernel. To use it, add O=<directory> to the make command line, E.G.: $ make O=/tmp/build And all the output files (including .config) will be located under /tmp/build. More finegrained configuration: =============================== You can specify a config-file for uClibc: $ make UCLIBC_CONFIG_FILE=/my/uClibc.config And you can specify a config-file for busybox: $ make BUSYBOX_CONFIG_FILE=/my/busybox.config To use a non-standard host-compiler (if you do not have 'gcc'), make sure that the compiler is in your PATH and that the library paths are setup properly, if your compiler is built dynamically: $ make HOSTCC=gcc-4.3.orig HOSTCXX=gcc-4.3-mine Depending on your configuration, there are some targets you can use to use menuconfig of certain packages. This includes: $ make HOSTCC=gcc-4.3 linux-menuconfig $ make HOSTCC=gcc-4.3 uclibc-menuconfig $ make HOSTCC=gcc-4.3 busybox-menuconfig Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@uclibc.org
