gdb can automatically load certain files as described in [1]. Such files could install pretty-printers for complex data structures. libstdcxx (C++ standard library) provided by gcc, is one example of a library for which such auto-load file is available. But there are other examples too, like libglib2. However, gdb will only auto-load files if the file is located in one of the locations treated as 'safe'. The Buildroot sysroot is not by default in that list. Provide a better debugging experience by adding the sysroot to the 'safe' list, via the gdbinit file prepared by Buildroot.

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.
