The new DirectFB version does not build with gcc 4.3 from the Blackfin toolchain. One of the reason is that va_copy has some issues, which were fixed in gcc 4.4.0 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36799). There are also some other issues, which were fixed by a patch proposed by Peter Seiderer at http://lists.busybox.net/pipermail/buildroot/2015-February/120281.html. However, it probably doesn't make a lot of sense to carry patches that are not upstream for such old compilers. Instead, this commit takes the action of making DirectFB available only on toolchains using gcc >= 4.5, which was tested with the Arago toolchain. gcc 4.4 could potentially work, but wasn't tested (it is no longer supported by the internal toolchain backend, and we don't have any toolchain based on gcc 4.4), so we take the safe decision of requiring at least gcc 4.5.

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.
