Firewall is blocking git protocol
Some firewalls will block the git protocol. A possible workaround is to configure Slicer by disabling the option
Slicer_USE_GIT_PROTOCOL. Then the http protocol will be used instead. Consider also reading https://github.com/commontk/CTK/issues/33.
CMake complains during configuration
CMake may not directly show what’s wrong; try to look for log files of the form BUILD/CMakeFiles/*.log (where BUILD is your build directory) to glean further information.
‘QSslSocket’ : is not a class or namespace name
This error message occurs if Slicer is configured to use SSL but Qt is built without SSL support.
Either set Slicer_USE_PYTHONQT_WITH_OPENSSL to OFF when configuring Slicer build in CMake, or build Qt with SSL support.
If you encounter any other error then you can ask help on the Slicer forum. Post your question in
Developer category, use the
Usually seeing the full build log is needed for investigating the issue. The full build log can be found in the build tree, its exact location depend on the operating system and how Slicer was built, so the easiest way to find it is to look for large
*.log files in the build tree. For example, you may find the full build log in
<Slicer_BUILD>\Testing\Temporary\LastBuild_<date>-<time>.log. Large amount of text cannot be included in forum posts, therefore it is recommended to upload the build log to somewhere (Dropbox, OneDrive, Google drive, etc.) and add the download link to the forum post.
