You can generate a text +document with 'make manual-text' and read output/docs/manual/manual.text. +Online documentation can be found at http://buildroot.org/docs.html + To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' -2) select the packages you wish to compile +2) select the target architecture and 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. +5) find the kernel, bootloader, root filesystem, etc. in output/images 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@buildroot.org +You can also find us on #buildroot on Freenode IRC. |
