where libpng.so.2 ?

[donw@fyi.net]

I'm trying to rpm my first file. rpm is reporting that it is missing dependency libpng.so.2

Where can I find it? and, more important
Where do I install it?

Thanks

when in doubt, use google. a quick search of "libpng" comes up with this site: http://www.libpng.org/pub/png/libpng.html

but for convenience, here is a link to the list of .rpms for the dependency you're looking for: http://rpm.pbone.net/index.php3/stat...rch/libpng-1.2. it depends on your distro, so just search that page for the right one. download it, then

cd into_the_directory_you_downloaded_it_to/
rpm -i filename_of_libpng_rpm_file.rpm

and that should be it. good luck.

I've been to both sites you recommended. I couldn't find the right file that installs libpng.so.2
A couple of them seemed to be for Mandrake 10.1 but when I downloaded them and checked them out with rpm -qpl they diidn't reveal anything like libpng.so.2.

I sure would apprecatie a little more explicit directions. sorry I'm such a newbie.

Rather then using RPM, use Mandrake's URPMI utility. It will d/l and install all the dependencies for you.

O.K. What's URPMI??

There's no man entry for it and it doesn't seem to be anywhere on my KDE desktop.

CORRECTION: I must have mistyped it the first time around. I found it!

You have to be root to use URPMI. Look here for a tutorial on using it:

It's down a ways, and it's called Installing software on Mandrake with urpm.

You may have to install it, but it's generally installed by default.

O.K. Jeremy,

I found and tried URPMI. I get the same failed error message. Package won't install because of failed depency libpng.so.2.

I'm tryiing to install that ^%%$# canonpixus950i.ppd that you sent me to for my canon i950 pritner. So far, it's been a damn furstrating experience.

Ahhhh.

Sorry, That rpm isn't in the URPMI reposatory, so URPMI wouldn't work.

I got that error as well. First, make sure you have the latest version of libpng installed (using URPMI, it should be simple ). Then, you can do one of two things... Make a sym link called libpng.so.2 to the real libpng.so.X, or use the --force option when installing the rpm. Since I still am slacking and haven't yet moddified my own file, I don't know for sure if either option will work 100%.

I will try to try it out tonight when I get home.

I tried installing the file using the URPMI --force option. It seemed to work.
I hacked the driver file and installed the new printner using it.
Can't get it to print a tst page.
Since you obvioulsy know more aobut this stuff than I do, I'm looking forward to your results tonight.

Please tell me via direct e-mail (donw@fyi.net) or this forum how it turns out.

Well, this is a no-go. I installed the rpm's using the same method you did, then edited the .ppd files. They show up in CUPS, but I can't print anything with them. Unfortunatly, I get the standard CUPS error which pretty much says "hey, this isn't working." The BJC 7004 driver works great for my i850, however, the photo printing isn't quite there yet. From some reason, it prints all pictures at 1/2 the height, but not width and I don't have borderless printing either.

I'll keep trying to get either working and I'll let you know my progress. My first attempt will be to install an old version of libpng so that I can have the libpng.so.2 that is required.
