Compiling, Building and Running processes

All three processes are suitable in some moment of application
development. However, seems that in Lazarus is quite simplyfied and
forced to uncondotonal compiling. Unfortunately, that have negative
consequence in compilation performance (and linking on computers with
relatively small ammount of memory regarding bug in GNU linker for
Win32). Suggestion is to separately threads all of these three cases,
similary as Delphi does:

Compiling (Ctrl-F9):
  - Conditional compiling related sources, in project,in cases:
    - When sources are changed or products of compilation do not
exists
    - When project options are changed

  - Conditional creating binaries, in cases
    - Binary do not exists
    - Any source file is recompiled
    - Products of compilations changed or do not exists
 
Building:
  - Forcing unconditional compiling of all related files in project
  - Creating all binaries

Running:
  - Compiling (if nothing changes, old executable remain intact)
  - Running executable

From Mantis issue #894 I have noticed that current problem is that may
occure situation when it is not possible to detect all change.

By upper schema, it is required only to track and update date of all
files (sources, product of compilation and binaries) related to
project in the moment of

  - Loading project/sources or related files.
  - Changing sources from IDE or external utilities (in the moment of
returning to IDE)
  - Check condition of tracksed data on any Compiling, Building and
Running process

My assumption is that similar techniques are  coded or planned,
however currently not implemented in IDE. As well, currently retuening
in IDE after changing some related file do not activate reverting
dialog immediately, which is necessary to keep tracks up to date. As
well, seems that are not monitored changes for all related files in
projects not opened in IDE.

You can turn on conditional compilation by unchecking the "Always
build"option on the Miscellaneous tab of the Project options

Unfortunately, since executable is always linking, that is not
suitable enough. Time to compile/link for even smallest applications
is very long on Windows with relatively small amount of memory
(<=128).

What you can do is on
Project -> Compiler Options -> compilation
uncheck the Compiler: call on run.
Then at least when you press F9 nothing is compiled/linked
