Old kernels (before 2.6.36) were defining XATTR_NAME_CAPS in <linux/capability.h>, but using XATTR_SECURITY_PREFIX and XATTR_CAPS_SUFFIX which were defined in the kernel-only part of <linux/xattr.h>. In kernel 2.6.36 (commit af4f136056c984b0aa67feed7d3170b958370b2f), the XATTR_NAME_CAPS definition was moved to the kernel-only part of <linux/xattr.h>. It's only in kernel 3.0 (commit 1dbe39424a43e56a6c9aed12661192af51dcdb9f) that <linux/xattr.h> was fixed to expose XATTR_NAME_CAPS and the related definitions to userspace. This is the reason why the target variant of libcap has a dependency on headers >= 3.0 for the moment. However, this doesn't solve the problem for the host variant of libcap, which doesn't build properly on old systems. To solve this, we simply add a patch that defines the missing definitions. Their values haven't changed over time since they are part of the kernel to userspace ABI.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
