Hi, I wanted to compile acpi-call-dkms on Debian/testing AMD64 with clang-8/experimental. When doing a... # LC_ALL=C dkms install -m acpi-call -v 1.1.0 -k 4.20.0-rc2-2-amd64-cbl ...I saw that arch/x86/kernel/macros.s file was missing. My workaround was... $ cd $BUILD_DIR $ sudo cp -av arch/x86/kernel/macros.s /usr/src/linux-headers-4.20.0-rc2-2-amd64-cbl/arch/x86/kernel/ I guess the generated linux-headers debian package is missing this file. I wanted to let you and others know. Regards, - Sedat -
