[vdr] porting vdr-plugin-sc from FFdecsa to dvbcsa: undefined symbol
Hi All, I am trying to run vdr-plugin-sc on my D-link DNS323 running debian. This NAS has an ARM processor, so FFdecsa fails to compile. I am however able to compile and run vdr-plugin-dvb-api. (I cannot connect to OSCAM yet, but that's another discussion) vdr-plugin-dvb-api has code to use both FFdecsa and dvbcsa. I have changed the source of vdr-plugin-sc to use dvbcsa. This compiles and installs fine, but I see the following error in /var/log/syslog when I start VDR vdr: [8061] ERROR: /usr/lib/vdr/plugins/libvdr-sc.so.1.7.28: undefined symbol: _Z18dvbcsa_bs_key_freeP15dvbcsa_bs_key_s vdr: [8118] VDR version 1.7.28 started I see a strange thing with ldd, libdvbcsa.so.1 has not been linked in.

But why are they concatenated into one symbol?
Looks like you are using a plain C library with C++. The
undefined symbol is a C++ decorated one:
corei7:~ # c++filt _Z18dvbcsa_bs_key_freeP15dvbcsa_bs_key_s
dvbcsa_bs_key_free(dvbcsa_bs_key_s*)
corei7:~ #
It seems like the header files for libdvbcsa are not prepared for
C++. So the compiler puts a reference for a C++ decorated symbol
into the object file which the linker cannot resolve as the
library seems to contain only plain C symbols.
Try to put the #include statements for those header files into an
extern C block, like this:
extern C {
#include headerfile.h
}
This makes the compiler interpret the header file as plain C and
-- as a result -- generate plain C symbol references.
Hope this helps.
Bye.

Hi Reinhard,
It works! I have done what you said in cam.c. Now VDR starts the plugin without
error messages.
now let's add the configuration files for sc, and watch some pay-TV (hopefuly)
Thank you very much.

[vdr] popcorn hour A110 / HDX 1000 as vdr client?

I have been given an HDX 1000 (cross-flashed with the popcorn hour A110 firmware) I came across this german page, it looks like the A110 can be used as VDR client. http://www.popcornforum.de/showthread.php?tid=5201pid=176551#pid176551 Does anybody has experience with this ? Is there other / better ways to use the popcorn hour A110 as a vdr client? Kind regards, Cedric ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
