This patch is replaces two previous sumbissions, the first by Bernd Kuhls [1],
the second by me [2].
The posix_memalign declaration is incompatible with musl for C++ on x86, because
of the exception specification [2]. Note, the referenced patch is part of a
patch series to "Add musl support to GCC".
However, this build issue only happens if compilation is done with the GCC
compiler option '-pedantic' [3] which is done so in jsoncpp.
Fortunately, upstream accepted a patch to opt-out '-pedantic' [4]. We backport
this patch to fix autobuild errors.

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.
