It is extremely unlikely the above symptoms (both the ones described  
for 2.2.0 and 2.2.2) have anything to do whatsoever with Pascal  
support in gdb. It sounds much more like bugs in the internal debugger  
interface of the IDE (and as for the 2.2.2 symptom, I read that as  
"the 2.2.2 IDE won't even run for me").


in fact, gdb's Pascal support has been extremely stable (I've seen  
less than a handful regressions during the last 10 years). And that  
while the first basic Pascal test cases for gdb were only added during  
the last couple of years (by Pierre).

It may be the same as in C in certain cases on certain platforms when  
compiled with a particular version of FPC. Do not depend on it always  
being or remaining the same, because it *will* not work at some point.

[fpc-pascal] Failed to bootstrap under Linux (wrong filename casing, needs manual workaround)

[leledumbo]

I try to bootstrap my FPC, but I failed on:

Can't find unit variants used by db

when I check it out, the unit is there but with the wrong case. It's
Variants. The weird thing, only the .ppu is affected. The .o has the correct
case. Some other units also have the wrong casing. Even worse, one unit may
have the .ppu affected while others have their .o affected. I'm using
Freespire 2.0.8.

Re: [fpc-pascal] Converting C's bit field struct

[leledumbo]

Tried Vinzent solution and it works :clap:!
The layout is I think the same as in C. The difference is that FPC generates
it as

resb 4

while C uses

.comm 16

I don't know what .comm for. But since everything runs fine, who cares?
I just have some issues where assignment to the fields using pointer to that
type (^page_t) doesn't work. For instance:

var
  P: PPage; // the type is named TPage
...
with P^ do begin
  Present:=true;
  ReadWrite:=false;
  UserMode:=true;
  Frame:=FrameStack[FrameStackTop];
end;

When I check the value of each field, it's all ZERO! But the pointer isn't
nil. I guess the problem lies in my OS, but I'll do a re-check.

The debug problem is not really in our hands. We use the GNU debugger,
and if the GNU team (not exactly a cheering crowd of pascal fans) breaks 
things for Pascal, then we are pretty much powerless.

Secondly, can you look in the fp.cfg file using notepad, and see if there 
is a -Opentiom option somewhere in it ? If so, remove it. This option is
no longer supported.

Thirdly, you might consider simply (re)moving the file. As far as I know
(don't use the text mode IDE) the IDE will look for this file also in 
the current directory.

Michael.

Check the permissions on the file. You should be able to
write to it;
if you are under Vista, this may require some work.

I'd guess that a better test would be to open the file with Notepad and 
see if you are allowed to save changes (but from other messages on this 
list, it seems that there can be other issues...).


BTW: Please don't top-post on a mailing list! :-)
