hi there

I have migrated to Laz 0.9.11-20060116 (a clean, no-problem install on
Kubuntu 5.10 with "alien -c *"  ), and my project, wich has compiled
OK with 0.9.10, does not compile since.
this is the error:
Code: [Select](...).inc(32,14) Error: Illegal type conversion:
"ShortStrin" to "^Char"


this is the code:
Code: [Select]function GetFileSize(const FN:string):LongInt;
var
  R:tStatBuf;
begin
  if ( stat( pChar(FN), R ) = 0 ) then GetFileSize:=R.st_size else
GetFileSize:=-1;
end;

actually, I get *loads* of such errors. wtf?
(I suppose it's an FPC problem, but hope to get help here)
i cannot change the code, as it's from a library written by someone
else, besides - it's pointless and useless, too many places to change.

cheers
mike

P.S.
compiled Laz for GTK2! Yay, it looks *good*... :]

Apparently ansistrings have not been enabled.

This can be done by adding {$H+} in your source code. Note that {$mode
objfpc} turns ansistrings off. Recently fpc changed the parsing of
such global directives to solve some bugs and to become more
predictable. Now the order can be used to predict the outcome.

ok, that solved the problem. now my question is: is it a Bad Thing to
have AnsiStrings enabled, and if so - why?

thanks for the help
mike

IMHO, it is a good thing to have them enabled. It is just not done by
default because of backwards compatibility (just imagine all existing
code depending on the fact that strings are shortstrings ;-) ).
