We are seeing build issues with linux-pam in the autobuilders such as:
md5_crypt.c: In function 'Goodcrypt_md5':
md5_crypt.c:145:13: error: implicit declaration of function 'asprintf'; did you mean 'vsprintf'? [-Wimplicit-function-declaration]
145 | if (asprintf(&passwd, "%s%.*s$%s", magic, sl, sp, buf) < 0)
| ^~~~~~~~
| vsprintf
This is due to the fact that <stdio.h> gets included without
_GNU_SOURCE being defined, and so the prototype of asprintf() is not
accessible, at least with uclibc-ng.
The _GNU_SOURCE definition is properly in linux-pam's config.h, but
config.h doesn't get properly included first everywhere. This issue
has been fixed upstream in the mean time, so we simply backport the
upstream patch.

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 OFTC IRC.
