linux/autoconf.h and RED_HAT_LINUX_KERNEL

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. -- Féliciano Matias <feliciano.matias(a)free.fr&gt;
