Installing the libfdt headers at $(HOST_DIR)/include interferes with the build of the kernel, as in beaglebone: 2019-11-01T22:23:16 /usr/bin/make -f ./scripts/Makefile.build obj=scripts 2019-11-01T22:23:16 /usr/bin/make -f ./scripts/Makefile.build obj=scripts/dtc need-builtin= 2019-11-01T22:23:16 (cat /dev/null; ) > scripts/dtc/modules.order 2019-11-01T22:23:16 /usr/bin/gcc -O2 -I/work/beaglebone/host/include -L/work/beaglebone/host/lib -Wl,-rpath,/work/beaglebone/host/lib -Wp,-MD,scripts/dtc/libfdt/.fdt_ro.o.d -Wall -Wmissing-prototypes -Wstrict-p> 2019-11-01T22:23:16 scripts/dtc/libfdt/fdt_ro.c:92:10: error: redefinition of ‘fdt_get_max_phandle’ 2019-11-01T22:23:16 uint32_t fdt_get_max_phandle(const void *fdt) 2019-11-01T22:23:16 ^~~~~~~~~~~~~~~~~~~ 2019-11-01T22:23:16 In file included from scripts/dtc/libfdt/fdt_ro.c:54: 2019-11-01T22:23:16 /work/beaglebone/host/include/libfdt.h:384:24: note: previous definition of ‘fdt_get_max_phandle’ was here 2019-11-01T22:23:16 static inline uint32_t fdt_get_max_phandle(const void *fdt) 2019-11-01T22:23:16 ^~~~~~~~~~~~~~~~~~~ 2019-11-01T22:23:16 make[4]: *** [scripts/Makefile.host:107: scripts/dtc/libfdt/fdt_ro.o] Error 1 2019-11-01T22:23:16 make[3]: *** [scripts/Makefile.build:544: scripts/dtc] Error 2 2019-11-01T22:23:16 make[2]: *** [Makefile:1066: scripts] Error 2 2019-11-01T22:23:16 make[1]: *** [package/pkg-generic.mk:241: /work/beaglebone/build/linux-4dae378bbe721277b08699d1d88ffae12acc9b09/.stamp_built] Error 2 We cannot simply disable dtc support and patching the kernel makefiles is risky and error-prone, so let's just install the host-dtc headers at $(HOST_DIR)/include/libfdt to circumvent the problem. Packages that depend on those headers (e.g. host-qemu) must be updated to user the correct path but this is small change.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
