Spready in fpspreadsheet v1.8? This should not be. Spready has been removed from the fpspreadsheet installation some time ago, it can be found in the applications folder of the ccr repository. And I just tested Lazarus trunk and 1.6.4 with it - it compiles and runs fine. Maybe you still have an older version somewhere in your fpspreadsheet folder. This probaby will not compile with current fpspreadsheet.Unfortunately there is not ready-to-use zip file for spready. You either use svn and load the spready repository from svn, or you download the snapshot of the entire ccr repository and delete everything except spready (https://sourceforge.net/code-snapshots/svn/l/la/lazarus-ccr/svn/lazarus-ccr-svn-5806.zip).
