Hello Bastian, Thanks for reporting this. And apologies for a late reply.
To address this FTBFS issue, I uploaded the following changes to s <http://mentors.debian.net>alsa. * fix FTBFS on several release architectures * fix FTBFS error on armel * Remove mipsel, mips64el, s390x as build target For further information, kindly visit the following URL: https://salsa.debian.org/dfukui/jsonnet/-/commits/debian/0.18.0+ds-2 If you don't mind, I would appreciate it if you sponsor and help me upload this package. The following are some technical comments. According to the original source code [0], c4core does not support the following CPU architectures: s390x, mipsel, mips64el Thus, we should drop these ones from the Architecture field on d/control. Meanwhile, debugbreak should have been successfully built by falling back to raising SIGTRAP [1] for several architectures, but build fails due to a bug in upstream. This issue has already been addressed [2], so a patch [3] was created and added to d/patches based on upstream. In a similar story, I fixed FTBFS on armel and filed a patch [4]. Thanks for reading.
