As one might have noticed, the process that Lazarus creates just calls
fpc. So basically, my guess is that fpc is not capable of detecting as
of now that the project need not be compiled and linked........ just a
guess.
It can't know if a program needs so be recompiled because an include file used
by the main program could have been changed.
It's not the compiler.
Lazarus itself needs to know whether it should call the compiler or not:
- The compiler doesn't recompile a unit unless it needs to.
(i.e. some source file is changed) It knows this because it stores
this information in a unit.
- However, the compiler does always recompile and link the program
itself. It has no way of knowing whether it needs to or not, because
the source files are not stored in the compiled program.
- For the same reasons, if you set a conditional define in the IDE,
then the program should be rebuilt. The compiler cannot detect this.
(You can also try this in Delphi: Delphi doesn't detect a change
in conditionals, and won't recompile units unless you say 'build')
