Hhm, kernel developer Diego Calleja García means, the following issue could be Gentoo specific, so I filed this bug here (original bug report can be found here http://bugzilla.kernel.org/show_bug.cgi?id=6458). Emerging the current sources and doing a "make menuconfig" and leaving the menu immediately with saying "yes" to save the config gives me these messages at the command line: n22 /usr/src # cd linux n22 /usr/src/linux # make menuconfig HOSTCC scripts/basic/fixdep HOSTCC scripts/basic/split-include HOSTCC scripts/basic/docproc HOSTCC scripts/kconfig/conf.o HOSTCC scripts/kconfig/kxgettext.o HOSTCC scripts/kconfig/mconf.o SHIPPED scripts/kconfig/zconf.tab.c SHIPPED scripts/kconfig/lex.zconf.c SHIPPED scripts/kconfig/zconf.hash.c HOSTCC scripts/kconfig/zconf.tab.o HOSTLD scripts/kconfig/mconf HOSTCC scripts/kconfig/lxdialog/checklist.o HOSTCC scripts/kconfig/lxdialog/inputbox.o HOSTCC scripts/kconfig/lxdialog/lxdialog.o HOSTCC scripts/kconfig/lxdialog/menubox.o HOSTCC scripts/kconfig/lxdialog/msgbox.o HOSTCC scripts/kconfig/lxdialog/textbox.o HOSTCC scripts/kconfig/lxdialog/util.o HOSTCC scripts/kconfig/lxdialog/yesno.o HOSTLD scripts/kconfig/lxdialog/lxdialog scripts/kconfig/mconf arch/i386/Kconfig # # using defaults found in arch/i386/defconfig # arch/i386/defconfig:13:warning: trying to assign nonexistent symbol CLEAN_COMPILE arch/i386/defconfig:121:warning: trying to assign nonexistent symbol HAVE_DEC_LOCK arch/i386/defconfig:171:warning: trying to assign nonexistent symbol PCI_USE_VECTOR arch/i386/defconfig:173:warning: trying to assign nonexistent symbol PCI_NAMES arch/i386/defconfig:216:warning: trying to assign nonexistent symbol PARPORT_PC_CML1 arch/i386/defconfig:220:warning: trying to assign nonexistent symbol PARPORT_OTHER arch/i386/defconfig:247:warning: trying to assign nonexistent symbol BLK_DEV_CARMEL arch/i386/defconfig:268:warning: trying to assign nonexistent symbol IDE_TASKFILE_IO arch/i386/defconfig:287:warning: trying to assign nonexistent symbol BLK_DEV_ADMA arch/i386/defconfig:360:warning: trying to assign nonexistent symbol SCSI_MEGARAID arch/i386/defconfig:371:warning: trying to assign nonexistent symbol SCSI_CPQFCTS arch/i386/defconfig:392:warning: trying to assign nonexistent symbol SCSI_QLOGIC_ISP arch/i386/defconfig:395:warning: trying to assign nonexistent symbol SCSI_QLA2XXX arch/i386/defconfig:401:warning: trying to assign nonexistent symbol SCSI_QLA6322 arch/i386/defconfig:455:warning: trying to assign nonexistent symbol IEEE1394_CMP arch/i386/defconfig:472:warning: trying to assign nonexistent symbol NETLINK_DEV arch/i386/defconfig:506:warning: trying to assign nonexistent symbol IP_NF_MATCH_LIMIT arch/i386/defconfig:508:warning: trying to assign nonexistent symbol IP_NF_MATCH_MAC arch/i386/defconfig:509:warning: trying to assign nonexistent symbol IP_NF_MATCH_PKTTYPE arch/i386/defconfig:510:warning: trying to assign nonexistent symbol IP_NF_MATCH_MARK arch/i386/defconfig:517:warning: trying to assign nonexistent symbol IP_NF_MATCH_LENGTH arch/i386/defconfig:519:warning: trying to assign nonexistent symbol IP_NF_MATCH_TCPMSS arch/i386/defconfig:520:warning: trying to assign nonexistent symbol IP_NF_MATCH_HELPER arch/i386/defconfig:521:warning: trying to assign nonexistent symbol IP_NF_MATCH_STATE arch/i386/defconfig:522:warning: trying to assign nonexistent symbol IP_NF_MATCH_CONNTRACK arch/i386/defconfig:537:warning: trying to assign nonexistent symbol IP_NF_TARGET_MARK arch/i386/defconfig:538:warning: trying to assign nonexistent symbol IP_NF_TARGET_CLASSIFY arch/i386/defconfig:545:warning: trying to assign nonexistent symbol IP_NF_TARGET_NOTRACK arch/i386/defconfig:564:warning: trying to assign nonexistent symbol NET_FASTROUTE arch/i386/defconfig:565:warning: trying to assign nonexistent symbol NET_HW_FLOWCONTROL arch/i386/defconfig:717:warning: trying to assign nonexistent symbol SOUND_GAMEPORT arch/i386/defconfig:773:warning: trying to assign nonexistent symbol QIC02_TAPE arch/i386/defconfig:809:warning: trying to assign nonexistent symbol DRM_GAMMA arch/i386/defconfig:985:warning: trying to assign nonexistent symbol USB_BLUETOOTH_TTY arch/i386/defconfig:995:warning: trying to assign nonexistent symbol USB_STORAGE_HP8200e arch/i386/defconfig:1021:warning: trying to assign nonexistent symbol USB_HPUSBSCSI arch/i386/defconfig:1056:warning: trying to assign nonexistent symbol USB_TIGL arch/i386/defconfig:1114:warning: trying to assign nonexistent symbol DEVFS_FS arch/i386/defconfig:1115:warning: trying to assign nonexistent symbol DEVPTS_FS_XATTR arch/i386/defconfig:1243:warning: trying to assign nonexistent symbol X86_STD_RESOURCES arch/i386/defconfig:1244:warning: trying to assign nonexistent symbol PC *** End of Linux kernel configuration. *** Execute 'make' to build the kernel or try 'make help'.

Please explain in detail how you initially configured your 2.6.16-r6 kernel, e.g. did you do this: emerge =gentoo-sources-2.6.16-r6 cd /usr/src/linux-2.6.16-gentoo-r6 make menuconfig and at this point configure the kernel *from scratch* or did you do something like: emerge =gentoo-sources-2.6.16-r6 cd /usr/src/linux-2.6.16-gentoo-r6 cp ../my-old-kernel/.config . make menuconfig and at this point view/change configuration options
First I made a "make mrproper && make menuconfig") and run into this issue, after that I decided to move the old sources under /usr/src to *.old, emerged the gentoo-sources again and did immediately a "make menuconfig" _without_ copying any old .config file back into the working dir. At both ways I observed the same behaviour. I am not sure whether I have observed the config errors for previuos releases of the 2.6.16-gentoo sources too, but now it's reproducible at my system :-( I use a stable Gentoo system, here are the usual infos: n22 $> emerge info Portage 2203-svn (default-linux/x86/2006.0, gcc-3.4.5, glibc-2.3.6-r3, 2.6.16-gentoo-r6 i686) ================================================================= System uname: 2.6.16-gentoo-r6 i686 Intel(R) Pentium(R) M processor 1700MHz Gentoo Base System version 1.6.14 ccache version 2.3 [enabled] dev-lang/python: 2.4.2 dev-python/pycrypto: [Not Present] dev-util/ccache: 2.3 dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=pentium-m -fomit-frame-pointer -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/eselect/compiler /etc/gconf /etc/revdep-rebuild /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -march=pentium-m -fomit-frame-pointer -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig ccache distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://ftp-stud.fht-esslingen.de/pub/Mirrors/gentoo/ http://194.117.143.69 http://85.25.128.62 http://194.117.143.70" LINGUAS="de en" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.de.gentoo.org/gentoo-portage" USE="x86 X aac acpi alsa apache2 arts audiofile avi berkdb bitmap-fonts bzip2 cdr cli crypt css cups curl dri dvd emboss encode exif expat fam ffmpeg font-server foomaticdb fortran gd gdbm gif glut gpm gstreamer gtk gtk2 idn imagemagick imlib ipv6 isdnlog jai java javascript jimi joystick jpeg junit kde lcms libg++ libwww live logrotate mad mbox mhash mikmod mmx mmxext mng motif mp3 mpeg mysql ncurses nls nptl nsplugin ogg opengl oss pam pcre pdflib perl php png pppd python qt quicktime readline real reflection rtc samba sdl session slp snmp spell spl sse sse2 ssl subversion tcltk tcpd tiff truetype truetype-fonts type1-fonts udev unicode usb userlocales vorbis win32codecs xine xml xml2 xorg xv xvid zlib video_cards_ati input_devices_keyboard input_devices_mouse linguas_de linguas_en userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, PORTAGE_RSYNC_EXTRA_OPTS, PORTAGE_RSYNC_OPTS, PORTDIR_OVERLAY
Okay, I see this too, but only on an x86 box, not an amd64 box (duh, the warnings are from i386/defconfig). The warnings do not cause the menuconfig to fail. This can easily be seen by doing: make mrproper && make defconfig > /dev/null
Okay, this same thing happens on stock 2.6.16, so it's not a gentoo problem.
This bug isn't about the warnings, its about the fact that you can produce an uncompilable kernel through menuconfig (see the upstream bug)
Toralf, please detail the path that you take around menuconfig to create this uncompilable setup.
Sorry, I didn't follow the original link. It's *still* not a gentoo bug, as I was able to reproduce with stock 2.6.16. I get this: [12:09:56 nox] linux-2.6.16# grep FM801 .config CONFIG_SND_FM801=y CONFIG_SND_FM801_TEA575X=m LD .tmp_vmlinux1 sound/built-in.o: In function `snd_fm801_free': fm801.c:(.text+0x3b1f7): undefined reference to `snd_tea575x_exit' sound/built-in.o: In function `snd_fm801_create': fm801.c:(.text+0x3b407): undefined reference to `snd_tea575x_init' make: *** [.tmp_vmlinux1] Error 1 I'll comment on the upstream bug.
Thanks, we'll let them fix it :)
