libglvnd is the GL Vendor-Neutral Dispatch library, used to dispatch GL calls across multiple GL implementations at runtime. Full GL support, as usual, requires (parts of) the X11 stack: libX11, libXext, and xorgproto (for glproto). However, with just libX11, it is possible to do EGL on X11. EGL and GLES have no dependencies. Note: x11 and glx are 'features', so need to be 'enabled' or 'disabled' (or 'auto', but we don't care in Buildroot), while egl and gles1/2 are 'booleans', so need to be 'true' or 'false'. When an actual provider for GL, EGL, or GLES is enabled, so must the corresponding flavour be enabled in libglvnd. Conversely, when there is no actual provider, the corresponding support must be disabled in libglvnd. So we make each flavour selectable with hidden options, which actual providers will have to select. The license for libglvnd itself is a custom license by NVidia. It is pretty close to MIT, but it's different (although Debian does classify it as MIT); SPDX has no identifier for that license either. As such, we choose to just identify it as 'libglvnd license', and let users deal that with their legal department. Additionally, libglvnd bundles some code from other projects, so we list them explicitly as well.

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