Running `ffmpeg` in the terminal without any arguments produces the following error: ffmpeg: symbol lookup error: /lib64/libsndfile.so.1: undefined symbol: mpg123_info2 I'm using the latest version ffmpeg-5.1.2-9.fc37.src.rpm. I have tried reinstalling ffmpeg, libsndfile (and libs, and devel), and mpg123 (and libs, and devel). ffmpeg is unusable at the moment
libsndfile needs to be rebuilt against a new mpg123.
What version do you have installed?

this is still weird, I tried it on fresh F37 installation and still can't reproduce it despite having exactly the same package versions libsndfile requires libmpg123.so.0 ( rpm -q libsndfile.x86_42 --requires | grep mpg123 ) and from that library it requires mpg123_info2 among others: # readelf -Ws /usr/lib64/libsndfile.so.1 | grep mpg123_info 121: 0000000000000000 0 FUNC GLOBAL DEFAULT UND mpg123_info2 this library is provided by mpg123-libs and it does contain definition of mpg123_info2 # readelf -Ws /usr/lib64/libmpg123.so.0 | grep info2 45: 000000000001b200 423 FUNC GLOBAL DEFAULT 13 mpg123_info2 so there is no reason for the error you see, Please add output of these commands on your system: $ ldd /usr/lib64/libsndfile.so.1 | grep mpg123 $ readelf -Ws /usr/lib64/libmpg123.so.0 | grep mpg123_info
$ ldd /usr/lib64/libsndfile.so.1 | grep mpg123 libmpg123.so.0 => /usr/local/lib/libmpg123.so.0 (0x00007fee85c16000) $ readelf -Ws /usr/lib64/libmpg123.so.0 | grep mpg123_info 38: 000000000001b040 439 FUNC GLOBAL DEFAULT 13 mpg123_info 45: 000000000001b200 423 FUNC GLOBAL DEFAULT 13 mpg123_info2
(In reply to Honza Pokorny from comment #5) > $ ldd /usr/lib64/libsndfile.so.1 | grep mpg123 > libmpg123.so.0 => /usr/local/lib/libmpg123.so.0 (0x00007fee85c16000) I think this is the issue and why I can't reproduce it. You have libmpg123 from some other source and it takes precedence over the system one when linking with libsndfile You will have to find out where is it from and if you still need it.
Problem solved! Thank you so much for your fast help.
