Cant install programs
 

when i try to install a rpm program i say:

rpm -ivh XXX.rpm
it says:
libstdc++-libc6.2-2.so.3 is needed by wine-cvs-unstripped-022703-1
or
libdc.so.0 is needed by dcgui-qt-cvs-20040825

what should i do?

Google on 'libc6.2-2.so.3', find a site that has the appropriate RPM for it for your machine/distro, install it and then reinstall XXX.rpm.

do i always have to search and install these programs?

This happens when the actual program you are trying to install relies on other libraries that it can't find on your system. If those libraries already happen to be installed on your system, then no, you won't get any dependency issues.

and can someone teach me how to install libc6.2-2.so.3 ?

i ve found a rpm includes libdc.so.0 but it wants another lib to be installed .... i founded it and wanted another lib...

will it go on forever?

Welcome to dependency hell. There are defintiely some programs that require a certain level of fanaticism in order to get working properly. You have to either decide to put up with it or find a different program that doesn't require so many libraries.
