So is that the technical issue with cross-platform resource compilers? The endian handling? Or is there some other technical issue? I remember even Kylix didn't have a resource compiler and couldn't understand why. After all, most C/C++ compilers are cross platform and they seem to have resource compilers, so what is wrong with Object Pascal compilers... Sorry if this is dumb, but I obviously don't understand the full issue here...

There you can also look how UseRES is used.

No. To compile .rc files to .res you still need windres. In general you
can compile and run it fine on little endian machines, but it doesn't
work (at least, it didn't work 6 months ago, don't know if newer
versions are endian safe) on big endian machines.
So there is still no .rc compiler. However the 2.3.1 fpcres is able to
compile dfm/lfm/xfm files.
Also, how do you access the resources? With TResourceStream?
With RTL functions like FindResource, LoadResource and so on.
TResourceStream uses these functions.

Re: [fpc-pascal] assigning a local function to a var
I'm not sure, but you could use TProcedure, some think like this:
procedure test;
function func_a (pass_str : ansistring) : boolean;
begin
writeln (pass_str, 'A');
func_a := true;
end;
function func_b (pass_str : ansistring) : boolean;
begin
writeln (pass_str, 'B');
func_b := false;
end;
var
// TProcedure
my_func : TProcedure
result: boolean ;
begin
my_func:= nil ;
if not Assigned(my_func) then begin
my_func:= TProcedure(@func_a);
result:= my_func('hello, ');
end
else begin .
end;
end;
Try it and let me know...

[fpc-pascal] Performance issue with dynamic arrays
Hi all!
While analyzing my project with valgrind, I discovered that almost a quarter
of the cpu cycle where eaten up by the function fpc_finalize_array. It seams
that fpc_finalize_array calls for every element of the array fpc_finalize. To
illustrate the problem i have written to small test programs:
program DynArray;
{$mode objfpc}{$H+}
var
i: Integer;
aArray: Array of Integer;
begin
SetLength(aArray, 100);
for i := 0 to 99 do
aArray[i] := i;
aArray := nil;
end.
program StaticArray;
{$mode objfpc}{$H+}
var
i: Integer;
aArray: PIntegerArray;
begin
GetMem(aArray, 100);
for i := 0 to 99 do
aArray^[i] := i;
FreeMem(aArray);
end.
According to valgrind:
Total CPU cycles:
DynArray: 32 243 842
StaticArray: 2 107 419
And in the last line (aArray := nil; / FreeMem(aArray);):
DynArray: 22 001 122
StaticArray: 0
In order to avoid the unnecessary calls to fpc_finalize i added the following
line to fpc_finalize_array:
begin
if PByte(typeinfo)^ in [tkAstring, tkWstring, tkArray, tkObject, tkRecord,
tkInterface, tkDynArray, tkVariant] then ...
After that i go:
Total CPU cycles - DynArray: 8 205 710.
As far as I can see this change doesn't cause memory leaks.
Regards Volker
