Swig has a compiled in absolute path to its data files, which can be overridden using the SWIG_LIB environment variable: https://github.com/swig/swig/blob/v4.1.1/Source/Modules/main.cxx#L931-L945 This unfortunately means that host-swig misbehaves when used in the SDK, as this points to the ${HOST_DIR}/bin of the build, which may not be available when the SDK is used. The issue was reported upstream but rejected in https://github.com/swig/swig/issues/253, so instead add a wrapper script which calculates a sensible SWIG_LIB relative to the wrapper location unless SWIG_LIB is set, similar to how we do it for E.G. gcc or pkgconf.

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 https://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.
