build all problem

[jpc]

testing some little code on dsPIC 30F3012 i found that library's seem to be included in the definition that are beyond possibility's of this processor. LCD8 is the first it encounters this way, probably some others suffer from the same. Definitions need checking therefore.

[jpc]

once the above problem occurred the compiler cannot return to 'normal' build , it keeps looking for all units as declared in the definition file. >Even quitting IDE and starting again does not solve the problem , the only way out is to build another program and reload the first after succesfull compilation. Somehow the compiler seems to remember more then we know about.

Hi,
You are probably using some of the board based initialization routines for lcd8 like Lcd8_Init_EasyDsPIC3. Sources for this routines are provided with the compiler in order to be adjusted for specific hardware and mcu. If you take a look at the header of this function it specifically says :

Requires : Mcu must have PORTB, PORTD and PORTF with corresponding pins.

It is your responsibility to make sure of that. If you are going to use some mcu other than the one used in the provided example you'll have to modify/adjsut the setup as well.

no , nothing alike , i only did a build-all instead of normal build . I i compile it for 4013 there is no problem , if io compile it again for 3012 all is ok BUT if next i do a BUILD ALL for 3012 the phenomena returns.

Can you please tell me exactly which example have you tried to rebuild for dsPIC3012?!

ok here a good test : i reduced the led-blinking example and reduced it to PORTB :

Code: Select all

program LED_BLINKING;

begin
  TRISB := $0000;
 { TRISC := $0000;
  TRISD := $0000;
  TRISF := $0000;}
  while TRUE do
    begin
      LATB := $0000;
     { LATC := $0000;
      LATD := $0000;
      LATF := $0000;}

      Delay_ms(500);

      LATB := $FFFF;
    {  LATC := $FFFF;
      LATD := $FFFF;
      LATF := $FFFF;}

      Delay_ms(500);
    end;
end.

now i change the processor to 30F3012 , build and compiles ok.
If however i do build all i have the problem. In this example build all is useless but i encoutered this in some code that uses unit , however nothing like using those library's in my unit.

in addition , once i get this problem , i change back to 30F4013 , recompile is ok. next change back to 30F3012 and even at normal build the same errors

Your problem is explained in my first post.
When you click build all button, compiler tries to rebuild all libraries listed into mcu def file for which it finds sources. Among them there is lcd8 setup file. This file, however has to be changed for dspic3012 since it hasn't got portf, or it needs to be excluded from the list when build all is done.
If we would have different setup files for each mcu it would be very frustration and hard for maintainance.
But, we'll see for the next release to change build all option to rebuild all project related files except libraries.
