Should it be this hard installing a software on Linux? dependencies and conflicts.

kevintse · 04-04-2008, 01:06 AM

I was trying to install eva QQ(an Instant Message client), and this software requires dependency on "kdelibs-3.3.1-3.6.i386.rpm
", so I tried installing it, but failed.
Below there is a error message:

error: Failed dependencies:
libcrypto.so.4 is needed by kdelibs-3.3.1-3.6.i386
libssl.so.4 is needed by kdelibs-3.3.1-3.6.i386
openssl = 0.9.7a is needed by kdelibs-3.3.1-3.6.i386
kdelibs < 6:3.5.2-6 conflicts with cups-1.2.4-11.14.el5.i386

there are three more dependencies and a conflict between kdelibs and cups-1.2.4-11.14.el5.i386. I didn't proceed cause I wondered if there would be endless dependencies. even if dependencies stop on those three dependencies, I wouldn't be able to fix the conflict myself, so how to end the dependency and fix the conflict? please help...

Any replies would be greatly appreciated.
Thanks in advance.

How are you attempting to install the software? If you are installing software via yum from a repo it should handle dependencies automatically.

I installed the kdelibs by typing on the console "rpm -ivh kdelibs-3.3.1-3.6.i386.rpm". while the eva QQ is a tarball, I followed the steps described in the README along the tarball, as follow:

Compile and Run
==============================================
1. enter eva directory, input
./configure --prefix=`kde-config --prefix`
2. then type,
make
and press enter
3. when making finished, input
su
make install
4. now, eva should be installed into your system. you can
open a console and type eva to run it.

as the kdelibs is not installed properly, further installation of the software certainly fails.

I am a newbie, just been with Linux for a couple of days, I don't know how to use yum. would you please tell me how to do that?

Quote:

yum install kdelibs

Would be an example of using yum(you need to be root). This would install the kdelibs to run a binary but to install one that you can compile to you would:

Quote:

yum install kdelibs-devel

The same format (-devel) applies to most compiled dependencies. Usually there will be a list of packages required included in the readme of most tarballs.

It is much easier to install rpms.
