error when open mplyer or gmplayer


* gmplayer: error while loading shared libraries: libmp3lame.so.0: cannot open shared object file: No such file or directory

mplayer: error while loading shared libraries: libmp3lame.so.0: cannot open shared object file: No such file or directory

i had installed lame-20011231-1.src.tgz but still unable to open mplayer. what should i do next?* ***solved***

now it gave me this error

mplayer: error while loading shared libraries: libpng.so.2: cannot open shared object file: No such file or directory

now u have to install libpng ;>

next time install such things with ya packet manager, otherwise u have always that kind of problems

what's the output of :

ls -l /usr/lib |grep libpng

?

egag

output as below:

lrwxrwxrwx 1 root root 10 2005-02-02 06:27 libpng.a -> libpng12.a

freeka: i had compiled libpng but still doesn't work

i have MPlayer-1.0pre5 running with the same libs. you've got .
do you have the same MPlayer version ?

egag

but mplayer is right, he want libpng.so.2 and this lib doesnt exist in ya lib directory, so make a link called libpng.so.2 to libpng.so and test

If you are using someones mplayer package, you'd be better off to get the mplayer source and run a ./configure --prefix=/usr --enable-gui && make and let it get YOUR libs. Mplayer does a great job of setting/getting the compile options and performance settings for your specific cpu.
Compiling mplayer on slack is a cake walk, don't be afraid to try it! ;-)

ah, it isn't self compiled.
that explains the difference.
( i didn't know there were packages for Slack. )

egag

ok, i go compile and try it out, thanks guys

is the below shown i had compiled successfully? it is not gui?

lol havent thought of someone wouldnt compile mplayer on his machine but use a precompiled binary version....

yea thats all correct, if ya want a gui try gmplayer

root@darkstar:~# gmplayer
-su: gmplayer: command not found

1. dont work as root for such things, only work as root for administrative stuff.... so ur daily work with ya linux machine should be 99% with ya user account...
2. have u installed gmplayer? when not installed, it cant start ;D

to have the gui when you compile from source you have to add --enable-gui e.g.
./configure --enable-gui
make
make install

trinoo@darkstar:~$ gmplayer
gmplayer: error while loading shared libraries: libpng.so.2: cannot open shared object file: No such file or directory

back to this error

where is this libpng.so.2, where i can get it from and place at which directory?
