[linux-dvb] Lots of unresolved symbols with new CVS driver (Re: Re:Announcement: new saa7146 driver core for the av7110 dvb driver)

[Michael Hunold]

Hello John,

If you can help me, I would be very much obliged. I am running RH 7.1 with kernel version 2.4.20. I have tried compiling several versions of driver without success. Currently I have the CVS snapshot from today (23/12/02) dvb-kernel and although I can get this to compile, as you will see below, I am seeing a lot of unresolved symbol errors.

Ok.

depmod: *** Unresolved symbols in /lib/modules/2.4.20/kernel/drivers/char/drm/sis.o
depmod: sis_free_Rsmp_ced25333
depmod: sis_malloc_Rsmp_a3329ed5
depmod: *** Unresolved symbols in /lib/modules/2.4.20/kernel/drivers/net/wan/comx.o
depmod: proc_get_inode

I don't know where these come from.

depmod: *** Unresolved symbols in /lib/modules/misc/dmxdev.o
depmod:         _mmx_memcpy_Rsmp_15670e2d
depmod: *** Unresolved symbols in /lib/modules/misc/dvb.o
depmod:         _mmx_memcpy_Rsmp_15670e2d
depmod: *** Unresolved symbols in /lib/modules/misc/dvb_demux.o
depmod:         _mmx_memcpy_Rsmp_15670e2d
depmod: *** Unresolved symbols in /lib/modules/misc/dvb_filter.o
depmod:         _mmx_memcpy_Rsmp_15670e2d
depmod: *** Unresolved symbols in /lib/modules/misc/dvb_firm.o
depmod:         dvb_root_addr
depmod:         dvb_dpram_addr
depmod:         dvb_dpram_len
depmod:         dvb_root_len
depmod: *** Unresolved symbols in /lib/modules/misc/dvb_frontend.o
depmod:         get_fast_time
depmod: *** Unresolved symbols in /lib/modules/misc/dvb_net.o
depmod:         _mmx_memcpy_Rsmp_15670e2d`

These are all "parts" of the dvb-core.o, ie. they are all linked together and are *not* stand alone modules.

Please make sure that you delete any remains of an "old" driver lying around.

Something like
> find /lib/modules -iname "*dvb*"
will show you where some of the old dvb stuff may be lying around. Have a look at the date stamp and be sure to delete all that cruft.

Make sure that you followed the README and rename any old "videodev.o" to something like "videodev.o.old" .

modprobe: Can't locate module i2c-core

Please delete all lines related to "i2c-core" from "driver.av7110" -- i2c-core is not needed any more.

Something is really screwed up. All videobuf_* symbols are in video-buf.o. Does this module get build at all?

Please do a "make clean && ./getlinks && make install" and show me the output.

Additionally, have a look where "make installe" installs the files, and, as already said above, make sure any old remains of the driver are deleted.

CU
Michael.
