Fix the following build failure with oprofile raised since bump of binutils to version 2.40 in commit35656482d3: configure: error: bfd library not found [...] configure:17928: checking for bfd_openr in -lbfd configure:17953: /home/buildroot/autobuild/run/instance-1/output-1/host/bin/arm-linux-gcc -o conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -g0 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 conftest.c -lbfd -liberty -lpopt -ldl -lintl >&5 /home/buildroot/autobuild/run/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/arm-buildroot-linux-uclibcgnueabi/12.3.0/../../../../arm-buildroot-linux-uclibcgnueabi/bin/ld: warning: libsframe.so.0, needed by /home/buildroot/autobuild/run/instance-1/output-1/host/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libbfd.so, not found (try using -rpath or -rpath-link) Indeed, in this case, libsframe is not installed even after applying commit1b4d921e1dbecause BR2_BINUTILS_VERSION_2_40_X is not selected by anyone (binutils package is selected by oprofile and the toolchain is not generated by buildroot) To fix this issue, invert the logic: install libsframe by default (i.e. when binutils is selected or with a buildroot toolchain). libsframe will not be installed only if binutils < 2.40 is detected.

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