Hi, On an ubuntu system the code builds ok but not all modules run properly; the issue I noticed was the cx23885 module gave these errors when loaded: [ 20.395552] cx23885: disagrees about version of symbol altera_init [ 20.395560] cx23885: Unknown symbol altera_init (err -22) The cause was that there were two altera-stapl modules in the /lib tree % find .-type f -name "altera_stapl.ko" ./kernel/drivers/misc/altera-stapl/altera-stapl.ko ./kernel/drivers/linux/drivers/misc/altera-stapl/altera-stapl.ko I traced that back to make_makefile.pl; it was not using the right directory names for any drivers in drivers/misc or drivers/staging. For example before the patch this line was being generated: n=0;for i in altera-stapl.ko;do if [ -f "$i" ]; then if [ $n -eq 0 ]; then echo -n " ../linux/drivers/misc/altera-stapl/: "; install -d /lib/modules/3.13.0-35-generic/kernel/drivers/media/../linux/drivers/misc/altera-stapl; fi; n=$(($n+1)); if [ $n -eq 4 ]; then echo; echo -n " "; n=1; fi; echo -n "$i "; install -m 644 -c $i /lib/modules/3.13.0-35-generic/kernel/drivers/media/../linux/drivers/misc/altera-stapl; fi; done; if [ $n -ne 0 ]; then echo; strip --strip-debug /lib/modules/3.13.0-35-generic/kernel/drivers/media/../linux/drivers/misc/altera-stapl/*.ko; fi; after applying this patch the same line is: n=0;for i in altera-stapl.ko;do if [ -f "$i" ]; then if [ $n -eq 0 ]; then echo -n " ../misc/altera-stapl/: "; install -d /lib/modules/3.13.0-35-generic/kernel/drivers/media/../misc/altera-stapl; fi; n=$(($n+1)); if [ $n -eq 4 ]; then echo; echo -n " "; n=1; fi; echo -n "$i "; install -m 644 -c $i /lib/modules/3.13.0-35-generic/kernel/drivers/media/../misc/altera-stapl; fi; done; if [ $n -ne 0 ]; then echo; strip --strip-debug /lib/modules/3.13.0-35-generic/kernel/drivers/media/../misc/altera-stapl/*.ko; fi; This also affects drivers in staging. The patch is below. Test system % cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=14.04 DISTRIB_CODENAME=trusty DISTRIB_DESCRIPTION="Ubuntu 14.04.1 LTS" % uname -a Linux ubuntu 3.13.0-25-generic #62-Ubuntu SMP Fri Aug 15 01:58:01 UTC 2014 i686 i686 i686 GNU/Linux Vince [patch] ensure correct install of modules from drivers/{misc,staging} v4l/scripts/make_mediafile.pl uses the %instdir hash to collate a list of directories in media_build/linux which contain Makefiles; it uses this data when constructing a dependency for the Makefile.media target. It also uses this hash to collate all the individual module names and generate code which installs the individual modules. But it gets the installation directory wrong in the case of modules outside the linux/drivers/media tree. To fix, do the collation of source locations and conversion into install locations as separate steps. signed-off-by: vincent.mcintyre@gmail.com -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
