Installing packages by library name -- how to get 64-bit?

[Whoever]

I would like to install a package by library name, however it always seems to select the 32-bit version. Is there any way to get yum to install the 64-bit version? For example:

Code: Select all

# yum install libQtSql.so.4

You can't install a library that way.

run
yum provides \*/libQtSql.so.4

Then yum install the indicated package.

You also have conflicting repositories installed and have not installed and configured priorities.

If you know what it's called then you can use

Code: Select all

yum install 'libQtSql.so.4()(64bit)'
