[lazarus] Lazarus 0.9.18 and compilation speed (what does it look for?)

[Alex Smirnov]

IDE version:      Lazarus 0.9.18 (fresh installation) OS:                     Windows XP and  Linux(Mandriva 2006) - same problem. Problem description: While Lazarus tries to compile something, it starts to search for several files - PPUs, Libraries, source files, etc.But IMHO, it searches things in a wrong (not optimal) way. And as a result it spends more then 99% of compilation time in this searching process. Here is the example: "(SYSTEM)   Loading unit SYSTEM Unitsearch: System.ppu ... Unitsearch: System.pp Searching file System.pp... not found ... Unitsearch: System.pas Searching file System.pas... not found ... Unitsearch: System.ppu Searching file System.ppu... not found ... ... Unitsearch: C:\lazarus\fpc\2.0.4\units\i386-win32\rtl\System.ppu Searching file C:\lazarus\fpc\2.0.4\units\i386-win32\rtl\System.ppu... found" SYSTEM.PPU is a basic unit. But Lazarus first tries to find file "System.pp" in the project root directory! And it takes Lazarus 23 attempts (!!!) ONLY to find System.ppu. More over, every time I will build the same project - Lazarus will spend 23 attempts to find System.ppu. First of all I think, it should be a list of system modules(libraries) to find them every time in the same place. If this is a compiler issue - we should put system units search path at the top of unit search list. Next, I think it is a good idea to store some search results in project file (like "Project.lpi")  to speedup the compilation process. I mean that all *.PPU/*.PAS/*.PP/*.A etc files that are parts of a project should be stored in "Project.lpi" with full path. So compiler will try to search them ONLY when they will be not found with this stored paths. Regards, Alexey.
