Dear Maintainer, some compiler flags are architecture specific and should not leak when cross-building. As an example, -fcf-protection is x86-specific, and the following fails: aarch64-linux-gnu-gcc-13 -fcf-protection Similarly, -mbranch-protection=standard is aarch64-specific, and the following fails: x86_64-linux-gnu-gcc-13 -mbranch-protection=standard For this reason, we must tell dh_auto_configure to pass the right flags explicitly when changing the architecture. With the attached patch sane-backends cleanly cross-builds from source. Thanks! Emanuele
