Hi, For some reason, I need support of QuickTime on my CentOS 7. So I searched the internet and found that something called "|libquicktime|" can provide that support. So I download the rpm file from http://rpmfind.net/linux/rpm2html/search.php?query=libquicktime%28x86-64%29. Then I ran command "|rpm -i libquicktime-1.2.4-31.el7.x86_64.rpm|" and got the following errors: |warning: libquicktime-1.2.4-31.el7.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID 66534c2b: NOKEY error: Failed dependencies: libfaac.so.0()(64bit) is needed by libquicktime-1.2.4-31.el7.x86_64 libfaad.so.2()(64bit) is needed by libquicktime-1.2.4-31.el7.x86_64 libmp3lame.so.0()(64bit) is needed by libquicktime-1.2.4-31.el7.x86_64 libquicktime.so.0()(64bit) is needed by libquicktime-1.2.4-31.el7.x86_64 libschroedinger-1.0.so.0()(64bit) is needed by libquicktime-1.2.4-31.el7.x86_64 libx264.so.142()(64bit) is needed by libquicktime-1.2.4-31.el7.x86_64 | I can install these missing dependencies by querying for their package name and installing them one by one *manually*. But this is so tedious and time consuming, so I am wondering if there is any one-strike single-line (or two) command that can automatically install all dependencies, as well as the target rpm file. I hear that yum has a similar function but I don't know how to use yum to install |libquicktime| because it complains "No package libquicktime available." Thanks for any (working) answer. PS: I'm using CentOS 7, so please don't point me to those too old CentOS 6 links. I've read them, they are only a waste of time on 7. Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/centos-docs/attachments/20150117/bef3bea5/attachment-0005.html>
