libglib2 recently changed to use the result of the autoconf macro to decide how to use strerror_r() in g_strerror() instead of embedding the same preprocessor condition as in glibc's strings.h (upstream commit c8e268bb was first included in release 2.53.4). Following this change, if ac_cv_func_strerror_r_char_p is incorrectly set to "no", the error string is an uninitialized buffer which cannot be encoded as UTF-8. The final result of this is that GLib functions that are expected to fill in an error pointer on failure in fact leave this pointing to NULL which is likely to cause a segfault in client applications. In fact the autoconf check compiles a test file but does not need to run it, so the test is safe when cross-compiling and returns the correct answer. So remove this cached value and let the configure script figure it out for itself, fixing g_strerror() on glibc systems.

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
