Dear Sirs ,

Compilation of sources having {$I \dir1\dir2\x.pas } kind statements are not giving the same compilation results by the FPC.EXE 2.2.2rc2 and FPC 2.2.0 .

Assume that there are the following directory structures :

Directory of C:\a

07/19/2008 01:17 PM <DIR> .
07/19/2008 01:17 PM <DIR> ..
07/19/2008 01:36 PM <DIR> B

Directory of C:\b

07/19/2008 01:46 PM <DIR> .
07/19/2008 01:46 PM <DIR> ..
07/19/2008 01:18 PM 161 HELLO-WORLD.PAS 1 File(s) 161 bytes

07/19/2008 01:34 PM <DIR> ..
07/19/2008 01:18 PM 161 HELLO-WORLD.PAS 1 File(s) 161 bytes

-------------------------------------------------------------------

The source "HELLO-WORLD.PAS" is the same in all of the directories :

Program Hello ;
Uses
    Cheers ;
{$I \A\C\Hellos.PAS }
Begin

Say_Hello
(
3

              ) ;

End .

-------------------------------------------------------------------

The source "\A\B\Cheers.PAS" is as follows :

Unit Cheers ;
Interface
Procedure Is_it_Problem ;
Implementation
{$I \A\C\Cheers-Welcome.PAS }

End .

-------------------------------------------------------------------

The source "\A\C\Cheers-Welcome.PAS" is as follows :

Procedure Is_it_Problem ;
Begin
Writeln ( 'Is there a problem ?' ) ;
End ;

-------------------------------------------------------------------

The source "\A\C\Hellos.PAS" is as follows :

Procedure Say_Hello
(
n : Integer

              ) ;

Var i : Integer ;
Begin
For i := 1 to N
Do
  Begin
  Writeln ( i , ' : ' , 'Hello , world .' ) ;
  Is_it_Problem ;
  End ;
End ;

-------------------------------------------------------------------

The compilation of "\a\b\HELLO-WORLD.PAS" is giving the following results :

c:\a\b > fpc -Fu\a\b hello-world.pas
c:\a\b > fpc hello-world.pas

Now let's delete the following parts :

\A\B\Cheers.O

Let's re-compile "Hello-World.PAS" after this deletion in the directories : c:\a\d , c:\b , and c:\e
WITHOUT first compilation in c:\a\b where unit CHEERS.PAS stays :

-------------------------------------------------------------------

CONCLUSION : Compilation of {$I \dir1\dir2\...\dirn\x.pas } statements are NOT
consistent with respect to changing order of compilation or presence of
compiled parts in the sense that when FPC starts to compile a unit which is NOT
in the current directory , it is NOT able to find
completely specified paths
of included files when they are NOT showing the current directory
( when *.ppu and/or *.o does NOT exist ) .

Thank you very much ,

Hi,
i have a dll compiled with fpc which i load it from my another dll compiled with vc++ using loadlibrary function. So far there was no problem,but with winmo 6.1 using loadlibrary will cause crashes and return NULL.so it doesnt load it at all!

I was wondering how can i pinpoint the problem.
my dll,uses units with initialization sections,could if any crash happen there causes library not to load?

because i guess loading library doesnt do anything but just moving it into memory space?(or does those initialization sectiors end up in dllmain,attach_process?)

So?

Regards,
Roozbeh GHolizadeh

Out of interest, what switches are you using to compile dll?

nothing special just default options,but i guess i have built all my libraris with -g option.

Well,i come to this.
dlls built with fpc does not work under wm6.1.
i am using ppcrossarm 2.3.1 from todays svn
building simple dll with one export function and linking to it all with fpc,makes program not to run under wm6.1,but works fine under older oses!

so?

i have downloaded fpc 2.2.0 from site,and used it to build the simple dll and program. first it complains about no "as" tool found.
dont know hwy i get this,but anyway i renamed arm-wince-as to as and again winmo 6.1 does not run the result files!

Hi,

I fixed the problem in rev. 11421.

Funny thing that I started to investigate this problem in morning today before your e-mails :)

Not funny thing is that took whole day to find out what caused the problem :(

Damn WM6.1!!!

Yury.

Thanks,
by the way why i need to define VER2_2 to compile successfully compiler? it gives me error in base.inc file,i have to define that,although my compiler version is 2.3.1

No idea.
I use FPC 2.2.0 as starting compiler for 'make cycle' and it works.
