Babeltrace 2 is a trace manipulation toolkit. The Babeltrace 2 project offers a library with a C API, Python 3 bindings, and a command-line tool which makes it very easy for mere mortals to view, convert, transform, and analyze traces. See <https://babeltrace.org/> for more details. Babeltrace 2 is a major update of Babeltrace 1 (Buildroot package `lttng-babeltrace`). Both projects are coinstallable. Except for the command-line tool (named `babeltrace2`), the Babeltrace 2 project is not backward compatible with Babeltrace 1. I'm naming this package `babeltrace2` instead of `lttng-babeltrace2` because, although it can read LTTng traces, the two projects are independent. All major distributions use `babeltrace2` as the Babeltrace 2 package's name. I'm keeping the `lttng-babeltrace` package because, as of this date, we still add bug and security fixes from time to time, therefore the project is not in EOL stage. Some external, custom packages could still depend on the Babeltrace 1 library, for example. As with `lttng-babeltrace`, you can build and install the host version of Babeltrace 2 for the workflow where you trace the target, download the resulting trace (or receive it during the tracing process), and then read and analyze it with Babeltrace 2. If you enable the `elfutils` package (`BR2_PACKAGE_ELFUTILS`), then support for Babeltrace 2's debugging information filter component class is enabled. Tested with glibc, uClibc-ng, and musl.

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
