Compiler / linker errors are not within the scope of this forum. You are basically missing to provide the linker the implementation to the method FreezeTableWidget::FreezeTableWidget(QAbstractItemModel*).

Most likely you've only defined it in the header file and forgot to implement it in the source file OR you are missing to link against the file with the implementation.

If still unsure, try a C/C++ or general programming forum. This error is simply not Code::Blocks related.
