Subject: Compile error with glibc 2.3.2 + Linux 2.6.5 ARCH=x86_64

From: "David Lee" david.lee@xxxxxxxxxxxx

I am getting compiler errors when trying to compile glibc 2.3.2 using

the kernel headers from linux 2.6.5.  The headers from linux 2.6.3 work

fine.

I've traced the cause of the problem to a change made in

./include/asm-x86_64/unistd.h in the 2.6.4 release.

+#ifndef __ASSEMBLY__

+

+#include <linux/linkage.h>

+#include <linux/compiler.h>

+#include <linux/types.h>

+#include <asm/ptrace.h>

+

+asmlinkage long sys_ptrace(long request, long pid,

+                                unsigned long addr, long data);

+asmlinkage long sys_iopl(unsigned int level, struct pt_regs regs);

+asmlinkage long sys_ioperm(unsigned long from, unsigned long num, int

turn_on);

+struct sigaction;

+asmlinkage long sys_rt_sigaction(int sig,

+                                const struct sigaction __user *act,

+                                struct sigaction __user *oact,

+                                size_t sigsetsize);

+

+#endif  /* __ASSEMBLY__ */

Within glibc, ./sysdeps/unix/sysv/linux/x86_64/syscall.S ends up

including this file, which chokes the assembler with the struct

declarations in the above #include's.

/home/dlee/vcs/Products/Breeze/Dev/Prj/LinuxRH8/tscale2/tools/x86_64/x86

_64-linux/glibcinclude/linux/posix_types.h: Assembler messages:

/home/dlee/vcs/Products/Breeze/Dev/Prj/LinuxRH8/tscale2/tools/x86_64/x86

_64-linux/glibcinclude/linux/posix_types.h:36: Error: no such

instruction: `typedef struct{'

There are also errors about conflicting re-declarations further along in

the glibc build.

../posix/sys/types.h:62: error: conflicting types for `dev_t'

/home/dlee/vcs/Products/Breeze/Dev/Prj/LinuxRH8/tscale2/tools/x86_64/x86

_64-linux/glibcinclude/linux/types.h:23: error: previous declaration of

`dev_t'

Changing the '#ifndef __ASSEMBLY__' to '#if ((!defined __ASSEMBLY__) &&

(defined __KERNEL__))' clears up the problem.  My patch is below.
