BR2_BINFMT_FLAT configurations require the use of elf2flt. However, PHP uses -export-dynamic which breaks badly with elf2flt. Even a simple program fails to build: $ ./output/host/bin/arm-linux-gcc -Wl,-export-dynamic -o toto toto.c /home/thomas/projets/buildroot/output/host/opt/ext-toolchain/arm-buildroot-uclinux-uclibcgnueabi/bin/ld.real: section .junk LMA [0000000000000000,0000000000000027] overlaps section .text LMA [0000000000000000,0000000000006d07] -export-dynamic is clearly not useful for FLAT configurations, which are always statically linked, but it's quite a bit of work to change the PHP build system to use it only conditionall. It looks more like an interaction bug between gcc (which wants to put the .text section at address 0x0 in its linker script) and elf2flt, which wants to put its .junk section (containing the .rel.text stuff) also at address 0x0. Fixes (works around) the "section overlap" part of: http://autobuild.buildroot.net/results/35cbed8927bb10500ecf2816aa728ea240a0be21/ Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Cc: Waldemar Brodkorb <wbx@openadk.org> Signed-off-by: Peter Korsgaard <peter@korsgaard.com> |

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
