You can see a build logs at https://buildd.debian.org/status/fetch.php?pkg=horst&arch=s390x&ver=5.0-1&stamp=1503905687&raw=0 https://buildd.debian.org/status/fetch.php?pkg=horst&arch=ppc64el&ver=5.0-1&stamp=1503906226&raw=0 The error message looks identical (I checked the ppc64el log) to the problem with backend/sum.c: sparse -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security -std=gnu99 -Wall -Wextra -g -I. -DDO_DEBUG -I/usr/include/libnl3 *.[ch] /usr/include/powerpc64le-linux-gnu/gnu/stubs.h:8:12: error: unable to open 'gnu/stubs-32.h' Makefile:113: recipe for target 'check' failed make[1]: *** [check] Error 1 Best regards Uwe [1] https://packages.debian.org/sid/horst
