Lazarus program files very big, why?

I installed Lazarus on my Pi2B (see other therad) and am now using fpc 3.1.1 and Lazarus 1.5. I also installed tightvnc for GUI access via VNC from my Win7 PC.

My first test program on the Pi2B is a GUI application with 2 edit boxes and 2 buttons to test MD5 calculations. One button calculates MD5 of a text in one edit box and displays on the other. The other button calculates the MD5 of the Application.Exename (its own executable file) and displays the executable file name in one edit box and MD5 in the other. Total lines of code in the two events are 7.

Amazingly this little program is 24.5 Mbytes as shown: -rwxr-xr-x 1 root root 24493881 Oct 3 21:35 project1

So my questions are:
1) Why is Lazarus creating such an enormously big executable file?
2) Why is it placing the project files in /root/tmp? Why not in /home/pi/something_or_other?

Is this normal or have I installed Lazarus in some strange way that bypasses the user Pi?

Remove debug into at the project level, or run strip on the binary. note the install program's -s option, but that usually assumes that it can call strip to do the work which might not be the case on a non-development machine.

Always read FAQ before asking:
http://wiki.lazarus.freepascal.org/Lazarus_Faq#Why_are_the_generated_binaries_so_big.3F

2) Why is it placing the project files in /root/tmp?

Why not in /home/pi/something_or_other?

The setting is in Tools->Options->Environments->Files->Directory for building test projects, which defaults to tmp folder of your currently logged in user account.

Other than FAQ, reading other existing documentation is essential: http://wiki.lazarus.freepascal.org/IDE_Window:_Environment_Options#Files
