# How can I fix the linking errors when compiling

• I keep getting below error when compiling.

cannot find -lCore
cannot find -lTextEditor
cannot find -lAggregation
cannot find -lExtensionSystem
cannot find -lUtils

Where can I obtain those libraries?

I am trying to compile this plugin.

• Hi, your plugin refers to those .so files from the Qt Creator installation, they can be found there (libCore.so and libTextEditor.so are standard Qt Creator plugins, the other 3 are normal .dll/.so files).

To build successfully, set the QTC_BUILD env. variable in the .pro file to where your Qt Creator is installed, usually that's /home/yourname/Qt/Tools/QtCreator

Note: usually it's recommended that you download and compile/build Qt Creator yourself and set QTC_BUILD to point to that Qt Creator build, but when I compile my plugin, I usually cheat and just reuse the Qt Creator installation from the distribution (saves 20 minutes of waiting for gcc :-)
