NetBSD spiral.example.com 4.99.3 NetBSD 4.99.3 (SPIRAL) #456: Wed Oct 11 09:08:25 EDT 2006  root@spiral.example.com:/usr/obj/SPIRAL i386

>Description:
My build fails like this:

spiral:/usr/src/gnu/usr.bin/gdb6 #nbmake UPDATE=1 dependall
dependall ===> bfd
dependall ===> libiberty
dependall ===> opcodes
dependall ===> libgdb
/usr/obj/tooldir/bin/nbyacc: f - cannot open "/usr/src/gnu/dist/gdb6/gdb/objc-exp.c"

*** Failed target:  objc-exp.c
*** Failed command: /usr/obj/tooldir/bin/nbyacc -o /usr/src/gnu/dist/gdb6/gdb/objc-exp.c /usr/src/gnu/dist/gdb6/gdb/objc-exp.y
*** Error code 2

Stop.

*** Error code 1

Stop.

>How-To-Repeat:
I have /usr/src mounted read-only with various settingd in /etc/mk.conf:

WRKOBJDIR=/usr/obj/pkg
MKOBJDIRS=yes
MAKEOBJDIRPREFIX=/usr/obj
BSDSRCDIR=/usr/src
TOOLDIR=/usr/obj/tooldir

>Fix:
I mounted /usr/src read-write to rebuild that file.
