Hi. On a system with a working fasm, the patch below works for me.
Note: Without downgrading to debhelper compat 11, it fails in this way: dh_dwz: dwz -q -- debian/fasm/usr/bin/fasm returned exit code 1 make: *** [debian/rules:7: binary] Error 1 --- a/debian/control +++ b/debian/control @@ -3,7 +3,7 @@ Maintainer: Tomasz Buchert <tom...@debian.org> Section: devel Priority: optional Build-Depends: debhelper (>= 12), - debhelper-compat (= 12), + debhelper-compat (= 11), fasm, gcc-multilib [amd64], libc6-dev-i386 [amd64] --- a/debian/rules +++ b/debian/rules @@ -8,7 +8,8 @@ include /usr/share/dpkg/default.mk override_dh_install: mkdir -p debian/tmp - (cd source/libc; fasm fasm.asm; gcc $(CFLAGS) $(CPPFLAGS) $(LDFLAGS) -m32 fasm.o -o fasm) + cd source/libc && fasm fasm.asm && gcc $(CFLAGS) $(CPPFLAGS) $(LDFLAGS) -m32 fasm.o -o fasm + dh_install override_dh_clean: dh_clean Thanks.
