:All the modules do this. Remove "MODULES_WITH_WORLD" from your
:/etc/make.conf; they're not compatible with a read-only source tree.
I've partially tracked it down to the ILINKS target in kmod.mk being
run while in the wrong directory. It SHOULD be in
/FreeBSD/FreeBSD-current/src/sys/compile/TEST4/modules/3dfx
(aka /usr/src/sys/compile/TEST4/modules/3dfx). But instead,
when I echo `pwd` in the ILINKS target it appears to be cd'd into
the main modules source directory:
mv -f .newdep .depend
find ../../modules -type d -a ! -name CVS | sed -e "s|../../modules|modules|g" | xargs mkdir -p ; cd ../../modules ; env MAKEOBJDIRPREFIX=/FreeBSD/FreeBSD-current/src/sys/compile/TEST4/modules KMODDIR=/boot/kernel make depend
===> 3dfx
@ -> /FreeBSD/FreeBSD-current/src/sys
/FreeBSD/FreeBSD-current/src/sys/modules/3dfx <<<<<<<<<<<<<<<<<<<<<<<<<<<<
ln: @: Read-only file system
*** Error code 1
Stop in /FreeBSD/FreeBSD-current/src/sys/modules/3dfx.
*** Error code 1
Stop in /FreeBSD/FreeBSD-current/src/sys/modules.
This is not right. Someone did something to change the compile dir
as of the time the dependancies are run. The cd in the 'find' sequence
is correct
It looks like someone blew up the making of the object directories under
compile/TEST4/modules. Under 4.x I had paths like this:
/usr/src/sys/compile/TEST4/modules/FreeBSD/FreeBSD-current/usr/src/sys/modules/tx/....
Under -current they are like this:
/usr/src/sys/compile/TEST4/modules/tx/...
The 'make' program can't find the object module directory any more. Ahh..
so maybe I should remake the make program, eh? Tried that, doesn't work.
Whoever 'fixed' object directory creation under /usr/src/sys/compile/BLAH
for modules broke it instead.
