Hi all,
I have found a couple of bugs after downloading this last version
1) A minor one, already present in the previous beta (january): the specs file is
not correct. It seems to be the one used to cross-compile to DOS in your system.
The correct one is contained in the gcc2.8.1 distribution of djgpp v2.02 and I
have attached it for reference.
2) more serious a new bug (not present in the previous beta) has popped up in the
automake process. It occurs when an unit is referred to both directly in the
program and indirectly in an other unit as in the following example:
-----------------------------------------
file bug.pas
-----------------------------------------
program bug;
uses u,uu;
begin
writeln(O,K);
end.
------------------------------------------
file u.pas
------------------------------------------
unit u;
interface
uses uu;
var O:string[2] = 'O';
implementation
end.
----------------------------------------
file uu.pas
----------------------------------------
unit uu;
interface
var K: string[2] = 'K';
implementation
end.
-------------------------------------
compiled with
redir -o bug.out -eo gpc -v -g --automake -o bug.exe bug.pas
gives the attached bug.out file
The error is in the link stage. The files u.o and uu.o are not included in the ld
command (as they were in the previous beta).
If I include them explicitly with
gpc -v -g --automake -o bug.exe u.o uu.o bug.pas
all is correct
Hope this helps
Maurice
