Re: gcc-3.0.2: i686: builds; i586: fails

[pete at ltoi dot iap dot physik dot tu-darmstadt dot de]

Some further information on the build failure for i686, glibc-2.0.7,
SuSE-6.1, Kernel: linux-2.2.7.SuSE:

 Linux version 2.2.7 ... (gcc version 2.7.2.3) ... SMP

The error message

> ../../gcc-3.0.2/gcc/config/i386/linux.h:237:26: sys/ucontext.h: No such file

was right.

A  "locate ucontext.h"  exhibits:

/usr/src/linux-2.2.7.SuSE/include/asm-alpha/ucontext.h
/usr/src/linux-2.2.7.SuSE/include/asm-arm/ucontext.h
/usr/src/linux-2.2.7.SuSE/include/asm-i386/ucontext.h
/usr/src/linux-2.2.7.SuSE/include/asm-m68k/ucontext.h
/usr/src/linux-2.2.7.SuSE/include/asm-mips/ucontext.h
/usr/src/linux-2.2.7.SuSE/include/asm-ppc/ucontext.h

and /usr/src/linux-2.2.7.SuSE/include/asm-i386/ucontext.h contains

#ifndef _ASMi386_UCONTEXT_H
#define _ASMi386_UCONTEXT_H

struct ucontext {
        unsigned long     uc_flags;
        struct ucontext  *uc_link;
        stack_t           uc_stack;
        struct sigcontext uc_mcontext;
        sigset_t          uc_sigmask;   /* mask last for extensibility */
};

#endif /* !_ASMi386_UCONTEXT_H */

I have no idea, which location for this file is right one ...

 ... and, oh, btw. configure was called with

--prefix=/opt/gcc3.0.2
--exec-prefix=/opt/gcc3.0.2
--enable-languages=c,f77,c++

from a separte build directory from outside the source.
