The environment variables DESTDIR and INSTALL_MOD_PATH must be mutually exclusive. https://www.gnu.org/prep/standards/html_node/DESTDIR.html https://www.kernel.org/doc/Documentation/kbuild/modules.txt This issue was discussed in this Buildroot thread: https://lists.buildroot.org/pipermail/buildroot/2021-August/621350.html I saw this behavior in other different projects, as: - Yocto Project: https://www.yoctoproject.org/pipermail/meta-freescale/2013-August/004307.html - Google IA Coral: https://coral.googlesource.com/linux-imx-debian/+/refs/heads/master/debian/rules For the above reasons, INSTALL_MOD_PATH will be set as DESTDIR by default.
