I'm able to reproduce the issue I speak of with 100% reliability. Jeremie, I'm not sure why you're not able to reproduce this, because I can do so reliably/consistently. Below are my notes. This was done on a VMware Workstation VM instance, and I took VM snapshots along the way, so I can "roll back" to almost any phase/step listed below (in case someone wants me to verify what's on the filesystem or use "script" to save a log somewhere or run "make -DA" or something along those lines). 1. Installed 9.1-RELEASE. 2. Added ntpdate_enable and ntpd_enable to /etc/rc.conf, and ran /etc/rc.d/ntpdate start ; /etc/rc.d/ntpd start. 3. Added following to /etc/src.conf: WITHOUT_CDDL=true WITHOUT_CLANG=true WITHOUT_INET6=true WITHOUT_IPFILTER=true WITHOUT_LIB32=true WITHOUT_KERBEROS=true WITHOUT_PAM_SUPPORT=true WITHOUT_SENDMAIL=true WITHOUT_ZFS=true WITH_OPENSSH_NONE_CIPHER=true 4. Installed subversion via ports/pkg_add -r and pulled down a fresh copy of stable/9 (src, r249561) and ports. 5. Verified that /usr/bin/ctfconvert and other CTF utilities exist on system (obviously part of 9.1-RELEASE). 6. Followed instructions in src/Makefile. Shown here: # 1. `cd /usr/src' (or to the directory containing your source tree). # 2. `make buildworld' # 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). # 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). # [steps 3. & 4. can be combined by using the "kernel" target] # 5. `reboot' (in single user mode: boot -s from the loader prompt). # 6. `mergemaster -p' # 7. `make installworld' # 8. `make delete-old' # 9. `mergemaster' (you may wish to use -i, along with -U or -F). # 10. `reboot' # 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) Had to do "mergemaster -p" prior to installkernel, but Brooks knows about this and it's not relevant to the issue. 7. Verified the "make delete-old" phase deleted /usr/bin/ctfconvert and other CTF utilities; this is normal. 8. Removed WITHOUT_CDDL=true from /etc/src.conf 9. rm -fr /usr/obj/* && cd /usr/src && make -j2 buildworld. 10. Verification of everything at this point -- ctf* utilities are clearly in /usr/obj, but are not in /usr/bin (because of delete-old): root@testbox:/usr/src # find /usr/obj -name "ctf*" -type f -perm 0755 -ls 1783448 728 -rwxr-xr-x 1 root wheel 371738 Apr 17 15:29 /usr/obj/usr/src/cddl/usr.bin/ctfconvert/ctfconvert 1783453 64 -rwxr-xr-x 1 root wheel 28706 Apr 17 15:29 /usr/obj/usr/src/cddl/usr.bin/ctfdump/ctfdump 1783472 168 -rwxr-xr-x 1 root wheel 82711 Apr 17 15:29 /usr/obj/usr/src/cddl/usr.bin/ctfmerge/ctfmerge root@testbox:/usr/src # find /usr/bin -name "ctf*" -type f -perm 0755 -ls root@testbox:/usr/src # 11. make -j2 buildkernel fails: *** [aac_disk.o] Error code 127 cc -c -O2 -frename-registers -pipe -fno-strict-aliasing -std=c99 -g -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -Wundef -Wno-pointer-sign -fformat-extensions -Wmissing-include-dirs -fdiagnostics-show-option -nostdinc -I. -I/usr/src/sys -I/usr/src/sys/contrib/altq -D_KERNEL -DHAVE_KERNEL_OPTION_HEADERS -include opt_global.h -fno-common -finline-limit=8000 --param inline-unit-growth=100 --param large-function-growth=1000 -fno-omit-frame-pointer -mcmodel=kernel -mno-red-zone -mno-mmx -mno-sse -msoft-float -fno-asynchronous-unwind-tables -ffreestanding -fstack-protector -Werror /usr/src/sys/cam/cam.c ctfconvert -L VERSION -g cam.o ctfconvert: not found *** [cam.o] Error code 127 ctfconvert -L VERSION -g aac_cam.o ctfconvert: not found *** [aac_cam.o] Error code 127 2 errors *** [all] Error code 2 1 error *** [modules-all] Error code 2 2 errors *** [buildkernel] Error code 2 1 error *** [buildkernel] Error code 2 1 error I'll be doing the following to see where exactly the failure happens since as we know parallel make causes confusing output sometimes, rm -fr /usr/obj/* && make -j2 buildworld && make buildkernel I doubt the parallelism has anything to do with the issue, however -- it seems very clear cut to me that the issue is that buildkernel assumes ctfconvert is in one's $PATH, which is not true if you have an active system with WITHOUT_CDDL=true which you're trying to move *to* have CDDL. -- | Jeremy Chadwick j...@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Mountain View, CA, US | | Making life hard for others since 1977.
