ARCH_SUBDIR is computed based on the value of ARCH_SYSROOT_DIR and SYSROOT_DIR. For nested toolchains ARCH_SYSROOT_DIR is a subdir of SYSROOT_DIR, so a sed command like this one... sed -r -e "s:^${SYSROOT_DIR}(.*)/$:\1:" ...basically removes the leading SYSROOT_DIR part from ARCH_SYSROOT_DIR. But, for side-by-side sysroot toolchains ARCH_SYSROOT_DIR and SYSROOT_DIR are at the same level, so the above sed command doesn't make any effect. This patch therefore improves the calculation of ARCH_SUBDIR to clearly handle the three possible cases: - There is a single sysroot, or the selected architecture sysroot is the main one (i.e SYSROOT_DIR == ARCH_SYSROOT_DIR). In this case, ARCH_SUBDIR is empty. - There are side-by-side sysroots, such as SYSROOT_DIR=.../sysroot/mips-r2-hard/ and ARCH_SYSROOT_DIR=.../sysroot/mipsel-r2-hard/. - The arch-sysroot is nested, such as SYSROOT_DIR=.../sysroot and ARCH_SYSROOT_DIR=.../sysroot/armv4t/ Signed-off-by: Vicente Olivert Riera <Vincent.Riera@imgtec.com> [Thomas: improve the logic to handle the SYSROOT_DIR==ARCH_SYSROOT_DIR case.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.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
