Ok, I'm back to try to try building world on VirtualBox with a recent -CURRENT. So, on a new workstation, I've installed a new VirtualBox, downloaded the latest i386 snapshot and installed it: FreeBSD-11.0-CURRENT-i386-20140203-r261419-disc1.iso Things started to be shady when I tried to build and install ports-mgmt/pkg: % install -s -o root -g wheel -m 555 pkg-static /usr/ports/ports-mgmt/pkg/work/stage/usr/local/sbin/pkg-static % strip: /usr/ports/ports-mgmt/pkg/work/stage/usr/local/sbin/pkg-static: File format not recognized So I tried to disallow VFS unmapped bufs as you advised me and this seems to have solved the problem (but maybe by chance, see below). Now I'm still running with vfs.unmapped_buf_allowed=0, I installed all the ports I need for basic development. I fetched freebsd-src from GitHub and tried to build world... And now it's started to be very wacky: it failed, multiple times, but never at the same place (I removed /usr/obj/* between each run). There is at least something consistent, it always fails with the same error ".../.depend: Zero byte read from file, skipping rest of line.": % [jlh@freefall ~/www/wacky_buildworld_on_vbox]$ grep -B 1 -A 5 'warning: Zero byte read from file' * % typescript.fail1.txt-TMP=_depend$$; sed -e 's/^\([^\.]*\).o[ ]*:/\1.o \1.po \1.So:/' < .depend > $TMP; mv $TMP .depend % typescript.fail1.txt:make[4]: "/usr/obj/usr/src/kerberos5/lib/libheimbase/.depend" line 3: warning: Zero byte read from file, skipping rest of line. % typescript.fail1.txt-make[4]: "/usr/obj/usr/src/kerberos5/lib/libheimbase/.depend" line 3: Need an operator % typescript.fail1.txt-make[4]: "/usr/obj/usr/src/kerberos5/lib/libheimbase/.depend" line 4: Need an operator % typescript.fail1.txt-make[4]: Fatal errors encountered -- cannot continue % typescript.fail1.txt-make[4]: stopped in /usr/src/kerberos5/lib/libheimbase % typescript.fail1.txt-*** Error code 1 % -- % typescript.fail2.txt-TMP=_depend$$; sed -e 's/^\([^\.]*\).o[ ]*:/\1.o \1.po \1.So:/' < .depend > $TMP; mv $TMP .depend % typescript.fail2.txt:make[3]: "/usr/obj/usr/src/tmp/usr/src/kerberos5/lib/libvers/.depend" line 3: warning: Zero byte read from file, skipping rest of line. % typescript.fail2.txt-make[3]: "/usr/obj/usr/src/tmp/usr/src/kerberos5/lib/libvers/.depend" line 3: Need an operator % typescript.fail2.txt-make[3]: "/usr/obj/usr/src/tmp/usr/src/kerberos5/lib/libvers/.depend" line 4: Need an operator % typescript.fail2.txt-make[3]: Fatal errors encountered -- cannot continue % typescript.fail2.txt-make[3]: stopped in /usr/src/kerberos5/lib/libvers % typescript.fail2.txt-*** Error code 1 % -- % typescript.fail3.txt-echo libroken.so.11: /usr/obj/usr/src/tmp/usr/lib/libcrypt.a >> .depend % typescript.fail3.txt:make[4]: "/usr/obj/usr/src/kerberos5/lib/libroken/.depend" line 3: warning: Zero byte read from file, skipping rest of line. % typescript.fail3.txt-make[4]: "/usr/obj/usr/src/kerberos5/lib/libroken/.depend" line 3: Need an operator % typescript.fail3.txt-make[4]: "/usr/obj/usr/src/kerberos5/lib/libroken/.depend" line 4: Unknown directive % typescript.fail3.txt-make[4]: Fatal errors encountered -- cannot continue % typescript.fail3.txt-make[4]: stopped in /usr/src/kerberos5/lib/libroken % typescript.fail3.txt-*** Error code 1 % -- % typescript.fail4.txt-echo asn1_compile: /usr/lib/libc.a /usr/obj/usr/src/tmp/usr/src/kerberos5/tools/asn1_compile/../../lib/libroken/libroken.a /usr/obj/usr/src/tmp/usr/src/kerberos5/tools/asn1_compile/../../lib/libvers/libvers.a /usr/obj/usr/src/tmp/legacy/usr/lib/libegacy.a >> .depend % typescript.fail4.txt:make[3]: "/usr/obj/usr/src/tmp/usr/src/kerberos5/tools/asn1_compile/.depend" line 3: warning: Zero byte read from file, skipping rest of line. % typescript.fail4.txt-make[3]: "/usr/obj/usr/src/tmp/usr/src/kerberos5/tools/asn1_compile/.depend" line 3: Need an operator % typescript.fail4.txt-make[3]: "/usr/obj/usr/src/tmp/usr/src/kerberos5/tools/asn1_compile/.depend" line 4: Need an operator % typescript.fail4.txt-make[3]: Fatal errors encountered -- cannot continue % typescript.fail4.txt-make[3]: stopped in /usr/src/kerberos5/tools/asn1_compile Any idea how to debug this? -- Jeremie Le Hen Scientists say the world is made up of Protons, Neutrons and Electrons.
