The .stamp_patched rule currently uses shell loops and conditions to iterate over the patches in the package directory and BR2_GLOBAL_PATCH_DIRS and to select between the versioned and unversioned directory. We want to add the patch list to show-info as well, so we need a way to do this entirely in Make functions. Introduce the function pkg-patches-dirs in pkg-utils which copies this functionality in make syntax, and use it in the .stamp_patched rule. As an extra simplification, only consider the version directory if PKG_VERSION actually exists. Otherwise, we would use the directory with a slash appended for packages without version. Why this does work, it just looks weird for no reason. Furthermore, introduce the function pkg-patch-hash-dirs which simply enumerates the package directory and the package subdirectories of BR2_GLOBAL_PATCH_DIRS. This function is used for _HASH_FILES as well. Ideally, we should be able to factor our the handling of the version subdirectory between the patches and hashes as well. Unfortunately, they are treated subtly different: patches don't use the base directory if the version directory exists, while hashes do use the base directory. We don't want to change this behaviour.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
