Hello,

today I found a weird bug (?): if project's .lpr file is not in "Unit0" section of .lpi file, then IDE fails to produce executable without complaining.
I found this by opening old (~2 month) project with new (svn1.5) Lazarus: "Files" in ProjectInspector becomes empty (also as "Required Packages"), so I readded my project files and .lpr comes last. And then after compiling no executable is produced.

I tested with lazarus v1.2.6 and svn1.5(r47935) with fpc v2.6.4 on Linux 64bit.

  Steps to reproduce:
- start lazarus and create clean project of graphical Application;
- save project and close Lazarus;
- open project's .lpi file in editor and swap content of <Unit0> and
<Unit1> sections ->  <Filename Value="project1.lpr"/> goes in to <Unit1>;
- save file and open that project in Lazarus;
- Lazarus complains about "The project does not use the LCL unit
interfaces, ...", you can add "interfaces" or ignore - no matter;
- compile project (ctrl + F9) -> message "Compile Project, Target:
project1: Tvarka" (done) appears;
-  now try find produced executable - there is none.

Should I report a bug that order of units in <Units> section of .lpi file matters?

Sorry for my bad English.

Then you have to change
General/MainUnit/Value to 1

- save file and open that project in Lazarus; - Lazarus complains about "The project does not use the LCL unit interfaces, ...", you can add "interfaces" or ignore - no matter;

Correct.

- compile project (ctrl + F9) -> message "Compile Project, Target: project1: Tvarka" (done) appears; - now try find produced executable - there is none.

No, because the compiler compiled unit0.

Should I report a bug that order of units in <Units> section of .lpi file matters?

No.
The only documentation about the lpi file format is the IDE source itself. The MainUnit value exists since the beginning.
