Currently, the configurators are using $($(2)_MAKE_ENV), often derived from $(TARGE_MAKE_ENV), as the environment to be set when calling the various configurators. This means that our host tools are used first, most notably pkg-config (from host-pkgconf). However, this is inherently flawed. Our pkg-config, when set for the host, only searches .pc files in $(HOST_DIR) and never ever uses the ones from the host. For example, since we do not build a host-qt, our pkg-config would not find the host's QtCore.pc et al. Consequently, on some systems (but not on others?) most of the configurators fail to build, especially the latest kernel versions, as they have been starting to use pkg-config two years ago. Fix that by filtering-out sensible values out of the environment, but only when calling the configurators.

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.
