First, i am not a "kernel hacker".
If /usr/src/linux-2.4/include/linux/autoconf.h is generated by "make
menuconfig" or "oldconfig", ... the news autoconf.h doesn't include
linux/rhconfig.h.
It's normal since the original autoconf.h and rhconfig.h conform with
binary Redhat kernel supply with the distribution.
If i let autoconf.h untouched, "#include <linux/autoconf.h>" define the
RED_HAD_LINUX_KERNEL macro. That's nice.
But if a use a "custom" kernel (make mrproper, make...) ,
RED_HAT_LINUX_KERNEL macro is not more defined.
This cause some trouble with alsa-driver. I try to build alsa for RH9
from freshrpms :
http://shrike.freshrpms.net/rpm.html?id=856
Alsa's configure try to find out if a RedHat kernel is used :
boolvar=RED_HAT_LINUX_KERNEL
echo "$as_me:3104: checking for redhat kernel" >&5
echo $ECHO_N "checking for redhat kernel... $ECHO_C" >&6
ac_save_CFLAGS="$CFLAGS"
CFLAGS="$CFLAGS -I$CONFIG_SND_KERNELDIR/include"
boolchk=""
if test "$cross_compiling" = yes; then
echo "$as_me:3110: result: \"unknown\"" >&5
echo "${ECHO_T}\"unknown\"" >&6;boolchk=""
else
cat >conftest.$ac_ext <<_ACEOF
#line 3115 "configure"
#include "confdefs.h"
#include "$CONFIG_SND_KERNELDIR/include/linux/autoconf.h"
int main( void ) {
#ifndef $boolvar
exit(1);
#else
exit(0);
#endif
}
_ACEOF
This doesn't work with a custom kernel. Even with a not so custom kernel
:
$ make mrproper
$ cp configs/kernel___config .config
$ make dep
Perhaps, you can add RED_HAT_LINUX_KERNEL_SOURCE in autoconf.h and leave
RED_HAT_LINUX_KERNEL only in rhconfig.h.
