When linking against libnspr with musl toolchains we get undefined references to `getprotobyname_r' and `getprotobynumber_r', for example when compiling libnss: /home/test/autobuild/instance-1/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/lib/libnspr4.so: undefined reference to `getprotobyname_r' /home/test/autobuild/instance-1/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/lib/libnspr4.so: undefined reference to `getprotobynumber_r' That's because musl does not have an implementation of these functions, so we need to enable their internal implementation from libnspr. This patch was backported from Alpine Linux commit a162da839db0d3f8be94a5c1ad2e2e54e691c38a.

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.
