Source: busybox Version: 1.22.0 Severity: minor Dear Maintainer,
Hello, Using the rebuild infrastructure, your package fails to build with clang instead of gcc. The error message is like this: >>debianutils/lib.a(mktemp.o): In function `mktemp_main': >>/home/builder/workspace/busybox/busybox-1.22.0/build/udeb/debianutils/mktemp.c:96: >> warning: the use of `mktemp' is dangerous, better use `mkstemp' or `mkdtemp' >>archival/lib.a(tar.o): In function `tar_main': >>/home/builder/workspace/busybox/busybox-1.22.0/build/udeb/archival/tar.c:1180: >> undefined reference to `unpack_Z_stream' >>/usr/bin/ld: busybox_unstripped: hidden symbol `unpack_Z_stream' isn't defined >>/usr/bin/ld: final link failed: Bad value >>clang: error: linker command failed with exit code 1 (use -v to see >>invocation) I found this is because of one recipe's dependency wasn't satisfied when building this package with clang. I found a similar case here http://lists.busybox.net/pipermail/busybox/2013-January/078871.html. But changing optimization level which was mentioned in this thread wasn't worked for this package. So I fixed it by simply add a conditional statement in makefile to deal with this difference. Many thanks, Joseph. -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 4.0.5-1-ARCH (SMP w/8 CPU cores; PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8) Shell: /bin/sh linked to /bin/dash Init: unable to detect
