Re: V4L hg tree fails to compile against kernel 2.6.28
Thanks for your help. I pulled the code Actually, now the function definition in compat.h causes a compilation error: see first text below. I fixed that by inserting #include linux/err.h at line 38 in compat.h in my local branch After that, compilation succeeds. Now, the device will not install, as dvb_usb cannot install anymore. see second text below. Therefore, I have replaced the __kmalloc_track_caller with kmalloc (as it was in dvb_demux.c before the change 2ceef3d75547 at line 49 can you make both changes in the hg branch ? - make[2]: Entering directory `/usr/src/linux-headers-2.6.28-19-generic' CC [M] tuner-xc2028.o In file included from tuner-xc2028.c:19: compat.h: In function 'memdup_user': compat.h:50: error: implicit declaration of function 'ERR_PTR' compat.h:50: warning: return makes pointer from integer without a cast compat.h:54: warning: return makes pointer from integer without a cast In file included from include/linux/fs.h:1891, from include/linux/poll.h:11, from dvbdev.h:27, from dvb_frontend.h:43, from tuner-xc2028.h:10, from tuner-xc2028.c:22: include/linux/err.h: At top level: include/linux/err.h:22: error: conflicting types for 'ERR_PTR' sudo modprobe dvb-usb-rtl2831u ir_protocol=2 WARNING: Error inserting dvb_usb (/lib/modules/2.6.28-19-generic/kernel/drivers/media/dvb/dvb-usb/dvb-usb.ko): Unknown symbol in module, or unknown parameter (see dmesg) WARNING: Error inserting dvb_usb_dibusb_common (/lib/modules/2.6.28-19-generic/kernel/drivers/media/dvb/dvb-usb/dvb-usb-dibusb-common.ko): Unknown symbol in module, or unknown parameter (see dmesg) FATAL: Error inserting dvb_usb_rtl2831u (/lib/modules/2.6.28-19-generic/kernel/drivers/media/dvb/rtl2831/dvb-usb-rtl2831u.ko): Unknown symbol in module, or unknown parameter (see dmesg) in the system log, I find: dvb_core: Unknown symbol __kmalloc_track_caller dvb_core: Unknown symbol __kmalloc_track_caller Douglas Schilling Landgraf wrote: Hello Jan, On Tue, Aug 24, 2010 at 5:04 PM, Jan Hoogenraad jan-conceptro...@hoogenraad.net wrote: Douglas: On compiling with Linux 2.6.28-19-generic #62-Ubuntu I now get: dvb_demux.c: In function 'dvbdmx_write': dvb_demux.c:1137: error: implicit declaration of function 'memdup_user' dvb_demux.c:1137: warning: assignment makes pointer from integer without a cast This is probably due to changeset 2ceef3d75547 which introduced the use of this function: http://linuxtv.org/hg/v4l-dvb/diff/2ceef3d75547/linux/drivers/media/dvb/dvb-core/dvb_demux.c This function is not available in linux/string.h in kernel 2.6.29 and lower. http://lxr.free-electrons.com/source/include/linux/string.h?v=2.6.28 Could you please advise me on what to do ?

Re: V4L hg tree fails to compile against kernel 2.6.28
__kmalloc_track_caller is not avaiable in 2.6.28-19-generic #62-Ubuntu which just passes your cut at 2.6.26. Apparently, the code __kmalloc_track_caller is in the source archive for 2.6.28, but the kernel options were not such that the symbol is available. My guess is that it was changed in 2.6.30, where memory management was changed. Thus, 2.6.28, it needs to stay kmalloc.

Sorry this problem. Hi Douglas. Any estimate when this will be fixed? Was hoping it was already since new stable kernel 2.6.35.2 is out now but still the same problem when I tried just now. I am already working on it this weekend. I will reply this thread when finished. 2.6.35 should be working, let me know if not. Now, I need to backport the changes to old kernels and commit other patches in my pending list.
