The symbol _ZN7pcrecpp6no_argE is found in the libpcrecpp.so library, that is provided by libpcrecpp0 package.
The version of subtitleeditor present in sid works correctly with the libpcrecpp0 package present in sid, but the "undefined symbol" error happens both with the lenny version and the lenny security version. With sid's version (7.6-2): $ objdump -T /usr/lib/libpcrecpp.so.0.0.0 | grep _ZN7pcrecpp6no_argE 00008968 g DO .bss 00000008 Base _ZN7pcrecpp6no_argE With lenny's security version (7.4-1+lenny1): $ objdump -T /usr/lib/libpcrecpp.so.0.0.0 | grep _ZN7pcrecpp6no_argE 000088d8 g DO .bss 00000008 Base _ZN7pcrecpp6no_argE With lenny's version (7.4-1): $ objdump -T /usr/lib/libpcrecpp.so.0.0.0 | grep _ZN7pcrecpp6no_argE 000088d8 g DO .bss 00000008 Base _ZN7pcrecpp6no_argE I'm not sure if the variation in the location of the symbol makes any difference, but the symbol is definitely there. I don't know too much about this, but I suspect that dependency information provided by libpcrecpp should indicate 7.6 instead of what gets stored in the Depends line of subtitleeditor: Depends: (...), libpcre3 (>= 7.4), libpcrecpp0, (...) -- Besos, Maggie. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
