When using uclibc libdevmapper.so was calling dm_task_get_info_base() function recursively, leading to segmentation fault. This was happening because uclibc linker loader just takes first existing 'dm_task_get_info' (which is 'dm_task_get_info_base') symbol in elf binary, instead of default version. Add upstreamable lvm2 patch [1], which introduces --enable-symvers[=STYLE] switch. Use that switch to disable symbol versions, as we do not plan to support binaries compiled against old libdevmapper library. Fixes bug #10781.

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
