mORMot Open Source

I try to install mORMot in Lazarus 1.8.4 64bit FPC 3.0.4 on Windows 10 and run TestSQL3.lpi in folder SQLite3,
but there is an error when compile the project with message "SynFPCTypInfo.pas(190,31) Error: Identifier not found "AlignTypeData"".
How can I correct this?
Thank you in advance and sorry about my poor English.
