How to use diff file

[ruscoff]

Hi all,
i'm developing with Qt 4.8.4, i'm find a bug and it's solutions:
https://bugreports.qt-project.org/browse/QTBUG-2562?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel

They use .diff file, but i can't understand how to use it, i searched in google and find anything.

Can you help me?

Hi and welcome to devnet,

You must use the patch command and apply it to your Qt sources. Then build/install and use

Thank you, now it work.
But I had to search right file where to apply patch, are there ways to tell me what it the file? into diff file there are only number, not file name.

The info should be found in the diff file (depending on how you generated it), this one seems to miss them. It might be a good idea to add the information about which file should be patched to the bug report
