it would be easier if it was written en english but according to translator you have problems when compiling LazReport. Can you show some error messages so we can guess better?. what version do you use (lazreport, lazarus, fpc).
Don't know if it helps but try removing all .o and all *·ppu files in directory lazreport/source/lib and then try to compile again I usually have to do this after modifying lazreport sources (specially lr_desgn.pas)
