In the *-install-target phase the manifest file is being updated, if multiply packages try to update it they fail. To avoid multiple access to the manifest file use flock to sync multiple luarocks packages. e.g. installing three luarocks packages: make lua-cjson-build lua-coat-build lua-coatpersistent-build make lua-cjson lua-coat lua-coatpersistent -j Fix error: Updating manifest for /home/tetsuya/buildroot/br2/output/target/usr/lib/luarocks/rocks No existing manifest. Attempting to rebuild... Error: rock_manifest file not found for lua-coat 0.9.1-1 - not a LuaRocks 2 tree? [Thomas: get rid of LUAROCKS_RUN, and use LUAROCKS_RUN_ENV + LUAROCKS_RUN_CMD everywhere.] Signed-off-by: Fabio Porcedda <fabio.porcedda@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. 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 target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 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! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. 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.
