Hi, I found the problem, but don't know the cause or how to fix it.
First of all, my main code (project1.lpr) has just added the tree unit into "uses", but not actually use any of it. The problem occurs if I compile it using the Lazarus settings: fpc -MObjFPC -Scghi -O1 -g -gl -vewnhi -Filib/x86_64-linux -Fu. -FUlib/x86_64-linux/ -l project1.lpr However if I remove these -F, it is OK: fpc -MObjFPC -Scghi -O1 -g -gl -vewnhi -l project1.lpr Is this a bug in the compiler? I attached the complete source (3 files) so that you can test it. Thanks a lot! 2013/9/11 Xiangrong Fang <xrf...@gmail.com> > Hi All, > > Could anyone explain the error in attached image? > > Thanks a lot. > >
