MPlayer instalation prolems
 

Hello,
I am trying to install MPlayer on redhat 9. It requirers libpng and libpng-dev to compile.
I managed to install libpng 1.2.7, however i cannot find libpng-devel for 1.2.7 anywhere.
I found a libpng-dev for 1.2.7-1 but it wouldnt work with my 1.2.7, i guess they have to be exactally the same version.
Please help me out!

try using 1.2.6-1 of both libpng and libpng-dev

When I try to install the libpng i get this:

[root@localhost downloads]# rpm -ivh libpng-1.2.6-1.i386.rpm
warning: libpng-1.2.6-1.i386.rpm: V3 DSA signature: NOKEY, key ID 30c9ecf8

I guess i cant install it because i have the later version installed. I compiled the version thats already on my computer from source not an rpm tho so i have no idea how to get rid of it..

it looks like you have libpng-1.2.2 installed as well. uninstall both 1.2.7 and 1.2.2. don't ask me how to do this though cause i don't use rpms.

when i try and get rid of it i get the following:

rpm -e libpng-1.2.2-16

lol, don't you just love rpm dependency hell?

what distro are you using? if you're using FC/Redhat, i would suggest using up2date to install the newest versions of these package

Well i got both the libpng and libpng-dev installed!
Once i remembered why i needed them in the first place i tried to compile MPlayer again and got the same error msg i got over 5 hours ago:

Error: PNG support required for GUI compilation, please install libpng and libpng-dev packages.

back to the drawing board i guess...

what versions of libpng and libpng-dev do you now have installed? and what version of mplayer are you trying to install?

again, if you have up2date or some other system update utility, i would recommend using that to get the lib files and/or install mplayer.

How do you use up-2-date to install a spesific package? when I run it all that comes up atm is redhat-config-printer and mozzila mail.

The versions of both packages are 1.2.6-1 and im trying to compile MPlayer 1.0-pre5

Simply try to install libpng 1.2.6 with this option
rpm -Uhv libpng..... --test
if it says libraaries conflict with file of older package

use

rpm -Uhv libpng.... --replacefiles

You should not have trouble with other installed program.

cheers
