Package: gcc-4.8 Version: 4.8.1-7 Severity: normal Somewhere after 4.8.1-2 (I believe that version worked OK) I lost the ability to compile a working 64bit kernel on a 32bit userspace machine. This report is sent from a full 64bit machine, but it pertains only to the 32bit version of gcc-4.8 (same version)!
By working 64bit kernel I mean the kernel that can be successfully booted. The compilation phase actually finishes, but it is flooded with warnings like these: include/net/sock.h: In function ‘skb_add_data_nocache’: include/net/sock.h:1831:12: warning: pointer targets in passing argument 4 of ‘skb_do_copy_data_nocache’ differ in signedness [-Wpointer-sign] copy, offset); ^ include/net/sock.h:1805:19: note: expected ‘char *’ but argument is of type ‘unsigned char *’ static inline int skb_do_copy_data_nocache(struct sock *sk, struct sk_buff *skb, ^ include/linux/syscalls.h:536:17: note: expected ‘char *’ but argument is of type ‘unsigned char *’ asmlinkage long sys_read(unsigned int fd, char __user *buf, size_t count); ^ init/do_mounts_rd.c:134:2: warning: pointer targets in passing argument 2 of ‘sys_read’ differ in signedness [-Wpointer-sign] sys_read(fd, buf, size); ^ The resulting kernel crashes shortly after boot. -- System Information: Debian Release: jessie/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 3.11.0-rc1+ (SMP w/4 CPU cores; PREEMPT) Locale: LANG=C, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages gcc-4.8 depends on: ii binutils 2.23.52.20130620-1 ii cpp-4.8 4.8.1-7 ii gcc-4.8-base 4.8.1-7 ii libc6 2.17-7 ii libcloog-isl4 0.18.0-2 ii libgcc-4.8-dev 4.8.1-7 ii libgmp10 2:5.1.2+dfsg-2 ii libisl10 0.11.2-1 ii libmpc3 1.0.1-1 ii libmpfr4 3.1.1-1 ii zlib1g 1:1.2.8.dfsg-1 Versions of packages gcc-4.8 recommends: ii libc6-dev 2.17-7 Versions of packages gcc-4.8 suggests: pn binutils-gold <none> ii gcc-4.8-doc 4.8.1-1 pn gcc-4.8-locales <none> pn gcc-4.8-multilib <none> pn libasan0-dbg <none> pn libatomic1-dbg <none> pn libbacktrace1-dbg <none> pn libgcc1-dbg <none> pn libgomp1-dbg <none> pn libitm1-dbg <none> pn libmudflap0-4.8-dev <none> pn libmudflap0-dbg <none> pn libquadmath0-dbg <none> pn libtsan0-dbg <none> -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
