hi, all
While compiling glibc-2.1.3 with gcc-2.95.2 , I met error like the following
(as you know, I had already posted this error)
---------------------------------------------------------------
../sysdeps/unix/sysv/linux/i386/profil-counter.h: In function `profil_counter':
../sysdeps/unix/sysv/linux/i386/profil-counter.h:26: structure has no member
named `regs'
../sysdeps/posix/profil.c:39: warning: inlining failed in call to `profil_count'
../sysdeps/unix/sysv/linux/i386/profil-counter.h:26: warning: called from here
make[2]: ***
[/home/icekim/Cross-Compiler/Glibc/glibc-2.1.3/build/gmon/profil.o] Error 1
make[2]: Leaving directory `/home/icekim/Cross-Compiler/Glibc/glibc-2.1.3/gmon'
make[1]: *** [gmon/subdir_lib] Error 2
----------------------------------------------------------------------
I thought header files would probably cause a problem. While tracing header
files, I found a problem.
the following is sigcontext.h
-------------------------------------------------------------
struct sigcontext {
unsigned short gs, __gsh;
unsigned short fs, __fsh;
unsigned short es, __esh;
unsigned short ds, __dsh;
unsigned long edi;
unsigned long esi;
unsigned long ebp;
unsigned long esp;
unsigned long ebx;
unsigned long edx;
unsigned long ecx;
unsigned long eax;
unsigned long trapno;
unsigned long err;
unsigned long eip;
unsigned short cs, __csh;
unsigned long eflags;
unsigned long esp_at_signal;
unsigned short ss, __ssh;
struct _fpstate * fpstate;
unsigned long oldmask;
unsigned long cr2;
};
----------------------------------------------------------------------------
Like the above error message, struct sigcontext in the above sigcontext.h has
no 'member named `regs' .
Even though this problem might be solved in the process of the compilation (
indeed, this error passed with my clumsy trick), it also occurred while
compiling segfault.c like the following...
-----------------------------------------------------------------------------
powerpc-linux-gcc ../sysdeps/generic/segfault.c -c -O -Wall -Winline
-Wstrict-prototypes -Wwrite-strings -g -fpic -I../include -I.

-----------------------------------------------------------------------------
In this case I could avoid this error because function register_dump() in
register-dump.h uses 'regs' like the below.
-----------------------------------------------------------------------------
static void
register_dump (int fd, struct sigcontext *ctx)
{
char buffer[sizeof(dumpform)];
char *bufferpos;
unsigned regno;
unsigned *regs = (unsigned *)(ctx->regs);
memcpy(buffer, dumpform, sizeof(dumpform));
/* Generate the output. */
while ((bufferpos = memchr (buffer, '%', sizeof(dumpform))))
{
regno = xtoi (bufferpos[-1]) | xtoi (bufferpos[-2]) << 4;
memset (bufferpos-2, '0', 3);
_itoa_word (regs[regno], bufferpos+1, 16, 0);
}
/* Write the output. */
write (fd, buffer, sizeof(buffer));
}
-----------------------------------------------------------------------------
In fact, I don't understand what all members of struct sigcontext mean. I don't
know how to solve this problem. I hope somebody would help me.
