Even though we have some specific code to support building Qt5 for static-only configurations, it doesn't work. The first problem is that our custom qmake.conf always passes -ldl, which makes a number of Qt5 config.tests fail at configure time. Once this problem is fixed by removing -ldl from QMAKE_LIBS and adding it to QMAKE_LIBS_DYNLOAD instead, the next problem is that the plugin infrastructure of Qt5 assumes that Linux has dynamic library support: the qlibrary_unix.cpp file includes <dlfcn.h>, and the only condition for this file to not be included is: Until recently, building Qt5 statically was working because our C library was not built static-only: it provided <dlfcn.h> and libdl.so. But now that we have a really static only toolchain, Qt5 no longer builds. The easiest solution is to simply make Qt5 depend on dynamic library support.

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.
