Hi,
I needed the following patch to fix this compile error (which does not
happend at first compile):
[EMAIL PROTECTED]:/usr/src/linux-2.6.21-rc4-mm1 $ rm init/missing_syscalls.h
[EMAIL PROTECTED]:/usr/src/linux-2.6.21-rc4-mm1 $ make init
CHK include/linux/version.h
CHK include/linux/utsrelease.h
CHK include/linux/compile.h
GEN init/missing_syscalls.h
CC init/missing_syscalls.o
LD init/built-in.o
[EMAIL PROTECTED]:/usr/src/linux-2.6.21-rc4-mm1 $ cat
init/.missing_syscalls.h.cmd
cmd_init/missing_syscalls.h := sed -n
'/^\#define/s/[^_]*__NR_\([^[:space:]]*\).*/ \#if !defined (__NR_) \&\&
!defined (__IGNORE_)
\#warning syscall not implemented
\#endif/p' /usr/src/linux-2.6.21-rc4-mm1/include/asm-i386/unistd.h
>init/missing_syscalls.h
# (note all three \1 missing, replaced by char '^A', not visible here.

[EMAIL PROTECTED]:/usr/src/linux-2.6.21-rc4-mm1 $ make init
CHK include/linux/version.h
CHK include/linux/utsrelease.h
init/.missing_syscalls.h.cmd:2: *** séparateur manquant . Arrêt.
make: *** [init] Erreur 2
As far as I understand it, Makefile rule cmd_missing_syscalls (from
init/Makefile) is used twice in two different ways:
- At first compile:
- run the command directly from Makefile,
- dump this command to init/.missing_syscalls.h.cmd for further use;
- At every but first compile:
- run existing init/.missing_syscalls.h.cmd
Can someone confirm that this is the right way to patch this ?
Thanks,
- Stéphane.
# complain-about-missing-system-calls-fix.patch
# Make generation of init/missing_syscalls.h more robust.
# Note: This fix is required only for "all but first" compilations, and
# perhaps only on some configurations (cf. /bin/sh).
