Before commitca63464e37(package/python-numpy: bump to version 1.25.0), numpy was using python distuils. Then, the default for BLAS and LAPACK detection was to disable support if they were not found, even when OPENBLAS is installed on the host system. Commitca63464e37switched python-numpy to use the meson-package infrastructure, where the default has changed, and now fails when the host system does have OPENBLAS installed: buildroot$ make >>> host-python-numpy 1.25.0 Configuring [...] Run-time dependency openblas found: NO (tried pkgconfig and cmake) WARNING: CMake Toolchain: Failed to determine CMake compilers state Run-time dependency openblas found: YES 0.3.21 Dependency openblas found: YES 0.3.21 (cached) Program _build_utils/process_src_template.py found: YES (/path/to/buildroot/output/host/bin/python3 /path/to/buildroot/output/build/host-python-numpy-1.25.0/numpy/_build_utils/process_src_template.py) Program _build_utils/tempita.py found: YES (/path/to/buildroot/output/build/host-python-numpy-1.25.0/numpy/_build_utils/tempita.py) output/build/host-python-numpy-1.25.0/numpy/meson.build:201:44: ERROR: Could not get cmake variable and no default provided for <CMakeDependency OpenBLAS: True None> [...] Two obvious ways to correct this: - Add some kind of host-lapack / host-openblas dependency to host-python-numpy, or - Tell host-python-numpy not to look for (or rely on) external code. Because the host numpy environment shouldn't be doing any numerical heavy lifting, we opt for the latter here.

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
