DirectFB provides two options for debug: * --enable-debug-support (default is yes) * --enable-debug (default is no) The first one provides the functions to print debug information. These functions can be called inside DirectFB, or by an external DirectFB driver in another package. The second one enables verbose mode in DirectFB, using these functions. Buildroot currently provides an option for the second one only. The first one - which is necessary for the second one - is always enabled, because this is the default value. The new option (BR2_PACKAGE_DIRECTFB_DEBUG_SUPPORT) makes it possible to disable debugging support (--disable-debug-support) in order to build the library with no debug feature at all. When debugging support is disabled, the target installation path of drivers (/usr/lib/directfb-<version>) is suffixed with -pure. The public library (/usr/lib/libdirectfb.so) remains unchanged. Some external DirectFB drivers will install into /usr/lib/directfb-<version>-pure in release mode. For that reason, it is important that DirectFB can be configured to use this directory.

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.
