meson is able to distinguish between host (= native) and target (= cross) compilation. It will explicitly pass different options to pkg-config to distinguish them. Therefore, we don't need to use the pkg-config wrapper when using meson, and can instead pass the pkg-config settings through the cross-compilation.conf. This is important because in some situations (e.g. for the Python configuration), meson sets the PKG_CONFIG_LIBDIR variable to a different value before calling pkg-config. Relying on our wrapper script doesn't work in that case (except if the script would unconditionally set PKG_CONFIG_LIBDIR, which it doesn't do at the moment). Add the sys_root and pkg_config_lib settings to cross-compilation.conf and use pkgconf directly instead of the wrapper. Note that this requires us to substitute STAGING_DIR as well, with an absolute path. This is not a big deal since cross-compilation.conf is regenerated for every package.

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.
