linux - C++ Ubuntu. Multiple undefined references compiling with FFMPEG libs -


i installed ffmpeg libraries on ubuntu 12.10 , headers described here .

in c++ application uses ffmpeg when compiling (gcc) getting :

and more ....

when compile link against these libs:

-lfaac -lavformat -lavcodec -lavutil -lavfilter -lswscale

what problem ?

i managed compile.for interested:

first disabled modules (which don't use) :

./configure --enable-gpl --enable-libass --enable-libfaac --enable-libfdk-aac --enable-libmp3lame \ --disable-libopencore-amrnb --disable-libopencore-amrwb --disable-libspeex --enable-librtmp --disable-libtheora \ --enable-libvorbis --enable-libvpx --enable-x11grab --enable-libx264 --enable-nonfree --enable-version3

then linked rest of dependencies in order:

-lavformat -lavcodec -lfaac -lmp3lame -lfdk-aac -lvpx -lx264 -lavdevice -lyasm -lavutil -lswscale -lrtmp -lvorbisenc -lva

SPSS keyboard combination alters encoding -

my question not have programming practical issue on spss. accident keyword combination cannot remember because did not intend press changed encoding in spss , text in data in different language english shown small boxes. nevertheless, when kind of analysis performed different language text shown in output. does know reason? tried change encoding did not produce result. first, @ edit > options , see whether setting unicode or locale. might fix it. if have text in multiple languages, want unicode. otherwise, may have specific locale set wrong. can change set locale, need know locale want use.
