| # Wrapper for execution of cross-compiled introspection binaries. |
| # |
| # gobject-introspection compiles small binaries for the target and executes them |
| # at build time in order to dump introspection metadata for various libraries on |
| # the target. Since these binaries are compiled for the target and not the build |
| # host they cannot be run normally. This script uses the platform2_test wrapper |
| # to find the appropriate QEMU wrapper to emulate the target and to chroot into |
| # the sysroot in order to be able to succesfully execute these cross-compiled |
| # binaries. |
| # |
| # We pass the sysroot as an explicit argument to the platform2_test wrapper as |
| # well as the following arguments: |
| # |
| # 1. The platform2_test wrapper filters environment variables by a small |
| # allow-list. We explicitly forward the default value of LD_LIBRARY_PATH |
| # through the wrapper and add an additional value: Some of the introspection |
| # binaries need to link against a shared object built in |
| # gobject-introspection itself, which hasn't yet been installed to the |
| # sysroot since we're still in the compile phase of the package itself. So we |
| # add a subdirectory of the package's WORKDIR to LD_LIBRARY_PATH that we know |
| # contains the build artifacts so that the loader can properly discover them. |
| # We strip any leading instances of $SYSROOT from the WORKDIR path since we |
| # will be chroot-ing into the sysoot as part of the introspection binary |
| # execution. |
| # |
| # 2. Remove all instances of $SYSROOT from arguments to the introspection |
| # binaries. This also done because we are chroot-ing into sysroot already. |
| # `/build/$board` becomes `/`, so |
| # `--library-path='/build/$board/usr/lib/libfoo'` needs to become |
| # `--library-path='/usr/lib/libfoo'`. |
