Traditionally, Buildroot has a default of enabling thread support. However, with the current construct of the thread choice in the uclibc package, the m68k and microblaze architecture end up with no thread support as the default. In order to avoid having to explicit a more complicated "default" value for the choice, we take a simple approach: we order the 3 possible choices by order of "preference", since Kconfig selects the first selectable option in a choice by default. So, NPTL is first and is the default when available. Then comes linuxthreads which only gets selected as the default when NPTL is available. None is offered as a last choice (in the current implementation, it is never the default, since all architectures can have thread support, either through NPTL or linuxthreads). [Thomas: reworked according to Yann's comment that we could rely on the Kconfig behavior that selects the first available choice option.] 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.
