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. I guess I have forgot to tell the linker to use that library: # ldd /usr/lib/vdr/plugins/libsc-cardclient-30.so.1.7.28 libcrypto.so.1.0.0 => /usr/lib/arm-linux-gnueabi/libcrypto.so.1.0.0 (0xb6da5000) libcrypt.so.1 => /lib/arm-linux-gnueabi/libcrypt.so.1 (0xb6d73000) libstdc++.so.6 => /usr/lib/arm-linux-gnueabi/libstdc++.so.6 (0xb6ca4000) libm.so.6 => /lib/arm-linux-gnueabi/libm.so.6 (0xb6bfb000) libgcc_s.so.1 => /lib/arm-linux-gnueabi/libgcc_s.so.1 (0xb6bd1000) libc.so.6 => /lib/arm-linux-gnueabi/libc.so.6 (0xb6a9b000) libdl.so.2 => /lib/arm-linux-gnueabi/libdl.so.2 (0xb6a8f000) libz.so.1 => /lib/arm-linux-gnueabi/libz.so.1 (0xb6a71000) /lib/ld-linux.so.3 (0xb6f47000) # ldd /usr/lib/vdr/plugins/libvdr-sc.so.1.7.28 libcrypto.so.1.0.0 => /usr/lib/arm-linux-gnueabi/libcrypto.so.1.0.0 (0xb6d31000) libstdc++.so.6 => /usr/lib/arm-linux-gnueabi/libstdc++.so.6 (0xb6c61000) libm.so.6 => /lib/arm-linux-gnueabi/libm.so.6 (0xb6bb8000) libgcc_s.so.1 => /lib/arm-linux-gnueabi/libgcc_s.so.1 (0xb6b8e000) libc.so.6 => /lib/arm-linux-gnueabi/libc.so.6 (0xb6a58000) libdl.so.2 => /lib/arm-linux-gnueabi/libdl.so.2 (0xb6a4d000) libz.so.1 => /lib/arm-linux-gnueabi/libz.so.1 (0xb6a2e000) /lib/ld-linux.so.3 (0xb6f08000) # ldd /usr/lib/vdr/plugins/libvdr-dvbapi.so libdvbcsa.so.1 => /usr/lib/arm-linux-gnueabi/libdvbcsa.so.1 (0xb6f9b000) libstdc++.so.6 => /usr/lib/arm-linux-gnueabi/libstdc++.so.6 (0xb6ecb000) libm.so.6 => /lib/arm-linux-gnueabi/libm.so.6 (0xb6e22000) libgcc_s.so.1 => /lib/arm-linux-gnueabi/libgcc_s.so.1 (0xb6df8000) libc.so.6 => /lib/arm-linux-gnueabi/libc.so.6 (0xb6cc2000) /lib/ld-linux.so.3 (0xb6fe1000) Could somebody have a look at my Makefile (attached)? I suspect I made a mistake there Best regards, Cedric I have added -ldvbcsa to the makefile, but this did not solve the problem: ### Includes and Defines INCLUDES = -I$(VDRDIR) DEFINES = -DPLUGIN_NAME_I18N='"$(PLUGIN)"' SHAREDDEFINES = -DAPIVERSNUM=$(APIVERSNUM) -D_GNU_SOURCE LIBS = -lcrypto -ldvbcsa SHAREDLIBS = ldd now indeed reports the library being linked in: # ldd /usr/lib/vdr/plugins/libvdr-sc.so.1.7.28 libcrypto.so.1.0.0 => /usr/lib/arm-linux-gnueabi/libcrypto.so.1.0.0 (0xb6dfb000) libdvbcsa.so.1 => /usr/lib/arm-linux-gnueabi/libdvbcsa.so.1 (0xb6dd8000) libstdc++.so.6 => /usr/lib/arm-linux-gnueabi/libstdc++.so.6 (0xb6d09000) libm.so.6 => /lib/arm-linux-gnueabi/libm.so.6 (0xb6c60000) libgcc_s.so.1 => /lib/arm-linux-gnueabi/libgcc_s.so.1 (0xb6c36000) libc.so.6 => /lib/arm-linux-gnueabi/libc.so.6 (0xb6b00000) libdl.so.2 => /lib/arm-linux-gnueabi/libdl.so.2 (0xb6af4000) libz.so.1 => /lib/arm-linux-gnueabi/libz.so.1 (0xb6ad6000) /lib/ld-linux.so.3 (0xb6fd2000) But VDR still reports the error: vdr: [10991] ERROR: /usr/lib/vdr/plugins/libvdr-sc.so.1.7.28: undefined symbol: _Z18dvbcsa_bs_key_freeP15dvbcsa_bs_key_s vdr: [11048] VDR version 1.7.28 started And during the build, I got a warning that no symbold are used: g++ -g -Wall -Woverloaded-virtual -Wno-parentheses -O2 -fPIC -fno-strict-aliasing -shared sc.o data.o filter.o system.o misc.o cam.o device.o version.o smartcard.o network.o crypto.o system-common.o parse.o log.o override.o -lcrypto -ldvbcsa -o libvdr-sc.so ... dh_shlibdeps -pvdr-plugin-sc dpkg-shlibdeps: warning: package could avoid a useless dependency if debian/vdr-plugin-sc/usr/lib/vdr/plugins/libvdr-sc.so.1.7.28 was not linked against libdvbcsa.so.1 (it uses none of the library's symbols) dh_installdeb -plibvdr-sc-cardclient I find this odd, because /usr/include/dvbcsa/dvbcsa.h contains the function prototypes for both dvbcsa_bs_key_free and dvbcsa_bs_key_s : void dvbcsa_bs_key_free(struct dvbcsa_bs_key_s *key); struct dvbcsa_bs_key_s * dvbcsa_bs_key_alloc(void); But why are they concatenated into one symbol?
