Hi,

I am Xing, a PHD candidate in University of Utah. I am trying to compile and install an OpenVZ kernel in FEDORA8, but one error prevents me. The error is "No build ID note found in /var/tmp/kernel***". I have tried several ways to solve it but still failed. I introduced what I did to solve this problem and hope to get some help from you.

The procedure I did to build a kernel RPM from SRPM. 1). Install SCR RPM

-bash-3.2$ sudo rpm -ihv ~/openvz/ovzkernel-2.6.18-128.2.1.el5.028stab064.7.src.rpm 1:ovzkernel #######################################[100%]

2). Change buildid in kernel-ovz.spec

-bash-3.2$ vim ./SPECS/kernel-ovz.spec %define buildid .emulab_openvz_migration //for easy distinguish.

3). Prepare kernel source tree. -bash-3.2$ sudo rpmbuild -bp --target=`uname -m` kernel-ovz.spec Building target platforms: x86_64 Building for target x86_64

4). create my own patch I). -bash-3.2$ sudo cp -r ./BUILD/ovzkernel-2.6.18/linux-2.6.18.x86_64 ./BUILD/ovzkernel-2.6.18.orig -bash-3.2$ sudo cp -r BUILD/ovzkernel-2.6.18.orig BUILD/ovzkernel-2.6.18.new

II). -bash-3.2$ sudo vim BUILD/ovzkernel-2.6.18.new/kernel/cpt/cpt_files.h

#define check_one_vfsmount(mnt) \ (strcmp(mnt->mnt_sb->s_type->name, "rootfs") != 0 && \ strcmp(mnt->mnt_sb->s_type->name, "vzfs") != 0 && \ strcmp(mnt->mnt_sb->s_type->name, "ext3") != 0 && \ strcmp(mnt->mnt_sb->s_type->name, "ext2") != 0 && \ strcmp(mnt->mnt_sb->s_type->name, "simfs") != 0 && \ strcmp(mnt->mnt_sb->s_type->name, "unionfs") != 0 && \ strcmp(mnt->mnt_sb->s_type->name, "tmpfs") != 0 && \ strcmp(mnt->mnt_sb->s_type->name, "devpts") != 0 && \ strcmp(mnt->mnt_sb->s_type->name, "proc") != 0 && \ strcmp(mnt->mnt_sb->s_type->name, "sysfs") != 0 && \ strcmp(mnt->mnt_sb->s_type->name, "nfs") != 0 && \ strcmp(mnt->mnt_sb->s_type->name, "binfmt_misc") != 0)

III). Set LDFLAGS(I tried to set in some experiments) -bash-3.2$ sudo vim BUILD/ovzkernel-2.6.18.new/arch/x86_64/Makefile LDFLAGS := -m elf_x86_64 --build-id

IV). create the patch(patch can be reused. patch locates at ~/linux-2.6.18-nfs.patch) -bash-3.2$ cd BUILD -bash-3.2$ diff -uNrp ovzkernel-2.6.18.orig ovzkernel-2.6.18.new > ~/linux-2.6.18-openvz-nfs.patch

V). copy to $TOPDIR/SOURCE -bash-3.2$ sudo cp ~/linux-2.6.18-openvz-nfs.patch SOURCES/

5). change kernel spec file. sudo vim kernel-ovz.spec

I). add new patch into it.

Patch120000: linux-2.6.18-openvz-nfs.patch # End VZ patches

II). add patch command

%patch110008 -p1

%patch120000 -p1 %endif

6). set LDFLAGS in cmd -bash-3.2$ echo $LDFLAGS --build-id 7). Rebuild kernel RPMs. -bash-3.2$ sudo rpmbuild -bb --with baseonly --without debuginfo --target=`uname -m` ./SPECS/kernel-ovz.spec Building target platforms: x86_64 Building for target x86_64 ...

Without setting --build-id at BUILD/ovzkernel-2.6.18.new/arch/x86_64/Makefile, the error is as following: "extracting debug info from /var/tmp/kernel-2.6.18-128.2.1.el5.emulab_openvz_migration-root/usr/src/kernels/2.6.18-128.2.1.el5.emulab_openvz_migration-x86_64/scripts/genksyms/genksyms extracting debug info from /var/tmp/kernel-2.6.18-128.2.1.el5.emulab_openvz_migration-root/lib/modules/2.6.18-128.2.1.el5.emulab_openvz_migration/kernel/lib/ts_kmp.ko *** ERROR: No build ID note found in /var/tmp/kernel-2.6.18-128.2.1.el5.emulab_openvz_migration-root/lib/modules/2.6.18-128.2.1.el5.emulab_openvz_migration/kernel/lib/ts_kmp.ko xargs: stat: terminated by signal 13 error: Bad exit status from /var/tmp/rpm-tmp.5481 (%install)

If I set --build-id at BUILD/ovzkernel-2.6.18.new/arch/x86_64/Makefile, the error is as following: ld: warning: Cannot create .note.gnu.build-id section, --build-id ignored. ld: warning: Cannot create .note.gnu.build-id section, --build-id ignored. /bin/sh: line 1: 11125 Segmentation fault ld -m elf_x86_64 --build-id -r -o drivers/i2c/built-in.o drivers/i2c/busses/built-in.o drivers/i2c/chips/built-in.o drivers/i2c/algos/built-in.o make[2]: *** [drivers/i2c/built-in.o] Error 139 make[1]: *** [drivers/i2c] Error 2 make[1]: *** Waiting for unfinished jobs.... ld: warning: Cannot create .note.gnu.build-id section, --build-id ignored. ld: warning: Cannot create .note.gnu.build-id section, --build-id ignored. ld: warning: Cannot create .note.gnu.build-id section, --build-id ignored. make: *** [drivers] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.48864 (%build)

2). I also tried to add "%define _missing_build_ids_terminate_build 0" or "%define debug_package %{nil}" at the top of SPECS/kernel-ovz.spec, but it does not work and still reports "No BUILD ID" error.

3). If I tried to change $(LD) to $(CC) in /linux/Makefile(The top Makefile in Linux source tree), but it reports lots of "undefined reference" errors. == arch/x86_64/lib/lib.a(thunk.o): In function `__up_wakeup': (.sched.text+0xdf): undefined reference to `__up' /usr/lib64/libc_nonshared.a(elf-init.oS): In function `__libc_csu_init': (.text+0x1d): undefined reference to `__init_array_end' /usr/lib64/libc_nonshared.a(elf-init.oS): In function `__libc_csu_init': (.text+0x4a): undefined reference to `__init_array_start' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/crtend.o: In function `__do_global_ctors_aux': crtstuff.c:(.text+0x6): relocation truncated to fit: R_X86_64_32 against `.ctors' collect2: ld returned 1 exit status

4). Add LDFLAGS+=--build-id in kernel-ovz.spec before %build and %install. But it still reported "No BUILD ID" errors(If I remember correctly).

I really hope to receive any suggestions to solve this problem. Thanks for your help.
