crypt() is an optional glibc feature. Some distros, like Fedora 28, are phasing it out to be replaced with libxcrypt [1]. Unfortunately this change is only ABI compatible, not source code compatible, i.e. the code will compile with warnings about undefined crypt(), but the resulting binary will crash. Follow the guidance in the Fedora bug and include crypt.h when _XOPEN_CRYPT is not defined.

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.
