Getting Source Codes
The Qt 6.8 LTS Commercial source codes are available in the tqtc shadow repositories and their lts branches.
Note! To be able to clone the LTS sources, you must have a commercial license. An evaluation license does not provide access to the LTS sources.
Qt sources
To clone the Qt sources, follow the instructions:
- Register to Gerrit as instructed in [1]. Some notes:
- If you just want to clone the sources, you need to follow the instructions in steps 1-3 and either set an SSH key (step 5) or an HTTP password (step 7).
- If you are going to contribute to the Qt Project, step 4 is mandatory.
- Login to Gerrit and follow the instructions in [2] to clone the LTS source codes.
Yocto environment
If you are using the Yocto environment, please see instructions in https://doc.qt.io/Boot2Qt-6.8/b2qt-meta-qt6.html#using-commercial-qt.
Troubleshooting
Here are some tips for the most common issues. Please note that as a commercial customer you can also contact our support team.
- Please check your license. The LTS branches require a commercial license. An evaluation license does not provide access to the LTS sources.
- If you have used to work with the public Qt 5 repositories, please note that LTS sources are available via tqtc shadow repositories and a Gerrit account is needed for accessing them. Log in Gerrit and set up your account as instructed in [3].
- If you see the following error message at the end of the cloning command, it might refer to the network issues (for example, too slow connection): fatal: early EOF fatal: fetch-pack: invalid index-pack output Please wait a while and try again cloning sources.
