DragonFly bugs List (threaded) for 2004-01
Re: Upgrading from FreeBSD 4.8 (PZERO in usb.c)
:I have a spare disk that I installed FBSD 4.8 on. I cvsuped the latest
:Dragonfly source and tried to build the kernel with no success.
:It fails :
:/usr/src/sys/bus/usb/usb.c:824: warning: implicit declaration of function `selwakeuppri'
:/usr/src/sys/bus/usb/usb.c:824: `PZERO' undeclared (first use in this function)
:I did the following:
:Install FreeBSD 4.8
:Installed the cvsup-without-gui port
:rm -rf /usr/src /usr/obj
:cvsup the dragonfly sources
:rm -rf /usr/include
:rm -rf /usr/obj
:make buildkernel [ failed with 2 sec ]
:make depend all install
:make buildkernel [ fails at usb.c:824 ]
:>From some googling, it seems that PZERO is removed.
:the sources for usb still contain PZERO
:dragonfly# cd /usr/src/sys/bus/usb/
:dragonfly# grep PZERO *.c
:ehci.c: tsleep(&sc->sc_softwake, PZERO, "ehciab", 0);
:ohci.c: tsleep(&sc->sc_softwake, PZERO, "ohciab", 0);
:usb.c: selwakeuppri(&usb_selevent, PZERO);
:>From the original 4.8 sources PZERO is defined as 22,
:should I replace PZERO with 22 or another value ?
The problem likely is that you munged your 4.x installation by
installing the DFly includes on it. Buildworld was unable to build
its native toolset because the native compiler is generating FreeBSD
preprocessor defines and the source is trying to include DragonFly
When you run a buildworld or buildkernel target (which are the correct
the targets to run), you need to use the native environment installed
on the machine, which would be FreeBSD-4.8 in this case.
Once you complete the buildworld and buildkernel you should be able to
installkernel and installworld to overwrite the entire FreeBSD
