This patch adds a new config option BR2_PRIMARY_SITE_ONLY that, when set, restricts package downloads to the specified BR2_PRIMARY_SITE. If the package is not present on the primary site, the download fails. This is useful for project developers who want to ensure that the project can be built even if the upstream tarball locations disappear. [thomas.petazzoni@free-electrons.com: Extend config option help message with more details coming from the commit log. Added a dependency on the fact that a primary site has been defined. Without any primary site (the default configuration), this new option does not make any sense.] Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Acked-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> |

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
