Thanks Sven and Michael,
I will do as you proposed and simply use a pointer for now. Later once the

[fpc-pascal] Forward struct declaration in C
Hi,
I'm porting a piece of software to FPC but I got stuck at a forward struct
declaration. The situation is as folows.
Header 1 declares:
struct TaskHandle__;
typedef void (*CallBackProcPtr)(struct TaskHandle__ *task);
And Header2 provdes:
typedef struct TaskHandle__ { int unused; } *TaskHandle
However header 2 already references header 1 because it already contains
some other type definitions, so I cannot reference header 2 in header 1
because of a circular dependency. Can FPC do something similar to C and
define a forward record?

If I would store the offset each variable has at the time of writing (only need to do one time per record type), I could easily make the loading work (even if the ABI changes when the file is read back).

Thanks, I think everything is clear now. My plan now is to respect default padding and write records in one go to disk. The padding value will be written to the file header so the records can be read back one variable at a time when padding differs, otherwise they will be read back in one go again.

Are there some tests anywhere that show how the performance is impacted? I did some performance tests on win32 and it appears that both packed and unpacked objects and records all show exactly the same performance. Writing the individual variables in a record or object to file takes about 5.5 times longer than writing them at once. If someone wants my test app to run it on other platforms please let me know then I can post the code. I will do more testing later on mac and linux32. I'm interested how win64 and linux64 behave in this respect. So if someone has these architectures please let me know.

This would not force me to do manual padding in my structs. Say I use a value of 16 would that cover all ABI's FPC currently supports?

Endianess is indeed an issue I will be handling. It's my understanding now that by storing data in a packed record I will have the same behaviour (when it comes to aligning data in memory) over all platforms and architectures. Same applies to packed objects. However when objects have methods, does that change memory alignment (compared to different architectures)? Is there any impact when I start using object inheritance? The background behind my questions is the implementation of an IFF reader/writer in FPC. The reader/writer will be generated from available data types (simple ones as well as objects and records). To simplify the code I want to make use of the abstraction that FPC gives me.

[fpc-pascal] Memory alignment with FPC
Does FPC ensure the same memory alignment for records and objects
over different platforms? If I want to be sure to have the same
alignment must I use packed (with possibly some aligning assigned)
records instead in combination with data types that are guaranteed to be
of the same size over the different platforms (eg byte, word, single) ?
Or do unpacked records behave the same over different platforms?
When
memory is alligned (either with {$PACKRECORDS N} or unpacked, are the
padding bytes quaranteed to be #0 or are they undefined?
Any help
appreciated.

Hi Tomas, Thanks for clarifying. I will use PtrUInt to store the pointer
address in. BTW: the documentation it says not to use PtrInt because
it's signed and therefore smaller than a pointer (as in max value). Also
there seems to be an error in the documentation. On
http://www.freepascal.org/docs-html/rtl/system/ptruint.html [1] [4] it
is described that PtrUInt is an alias to DWord. However, it depends on
the architecture which type it actually is. Could someone please correct
the docs?

Nah, I
wasn't thinking about letting fpdoc predict anything. Instead though it
would be nice to introduce something that helps the documenter flag a
certain piece of code and let fpdoc know that it should show
alternatives or instead a separate piece of code (similar as examples
does).

Indeed,
it's not. ScriptName will contain "configure.ppx.pas". What I want it
that ParamStr(0) will contain the full filename to the script file
instead of the compiled version. This should be the default behaviour
imho b ecause it's an "executable" script and not a source file anymore.

[fpc-pascal] Problems with assigning pointers
I have some issues when assigning a pointer to a pointer variable. Consider this: TVertex = record x: double; y: double; end; PVertex = ^TVertex; TEdge = record v1: PVertex; v2: PVertex; end; I have assigned a value to a vertex variable. In my code I have an array of TEdge. When I try to assign a vertex to the edge element in the array the x value suddenly is changed to 3e-308 (or something similar). I don't understand why, perhaps someone could help me to figure this out.The code I'm using to assign the value is shown below. To my knowledge assigning a pointer this way is perfectly legal not? procedure add_edge(v1, v2: PVertex); begin inc(edge_count); SetLength(edge_list, edge_count); edge_list[edge_count - 1].v1 := v1; //___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

[fpc-pascal] Problems with fpdoc
Hi, I seem to have some problems using fpdoc in combination with html tags. When I enter some text (taken from the documentation) I get compilation errors: Text used: With Strings do For i:=Count-1 downto 0 do Delete(i); Compilation errors: [] Invalid description (illegal XML element: "#text") [] Invalid paragraph content [] Invalid description (illegal XML element: "#text") If I drop the tags, I still get compilation errors (just not the 2nd one) but to my surprise the pascal code is shown in the .chm file. However any text after this code section is ignored. So my question is, how am I supposed to use html tags inside the documentation? Is there a special switch needed? I'm using: 2.7.1 [2011/12/27] for i386 On a side note, I would like to include images in my documentation. How to do this? Is simply putting a tag enough and will these links be embedded in the chm file?

[fpc-pascal] Memory leak
While dabbling with pointers, I came across a memleak for which I
don't understand why it happens. Hopefully someone can help me with it.
mytest^.name := Format('%s.%.3d', ['name', 1]);
This assigns
'name.001' to the pointer variable but causes a memleak. If I assign the
same value as string constant no memleak occurs, so it must be something

Of course there is. As was stated earlier you need to make the
filehandle a global not a local variable. You could also handle it
differently and use a TStringList instead.
var
s: TStrings;
s :=
TStringList.Create;
s.LoadFromFile('MyFile.txt');

Re: [fpc-pascal] fpGUI powered by OpenGL
But why is it not possible to integrate this with the regular fpGUI ? Can you explain in a couple of sentences ? Can't remember having said that it was impossible with the current approach. In fact it is perfectly doable. However (free)glut and opengl are already available on a large number of platforms/targets. So if fpGUI is built upon these libs then you immediately take the benefit of being able to support these platforms. Additionally you don't have to implement a "complex" interface between the different platforms this is handled already by glut and opengl for you. So in effect it could make fpGUI simpler. And the last plus is having a hardware accelerated gui. It just means it's lightning fast and that's a plus for UI's. Thats not all however, there are minusses. By using glut, you limit yourself to the supported platforms/targets. So if new platforms/targets come along then there is no way (unless you supply patches to the project) to add them. With the current approach you're free to do it yourself. Also the API is plain rigid. This means you'll have to adapt to that and live with it (notice it's a plus and minus depending on how you look at it). (That is why I would like to see a fpGlut some day ;) and believe me it will come to that eventually!) I probably forgot a few plusses and minusses, but that's about it as far as I'm concerned. Also I don't mean to say that using an opengl/glut backend is superior to the current ones. It just has other benefits I suppose.

If you don't set the BaseInstall dir it gets placed in c:\program files\whatever, but the base directory should be c:\program files\projectname\whatever (or c:\fpc\whatever resp c:\fpc\utils\whatever). The basedir should probably be set as an env string in any case (whith more complex projects involved) or just hardcoded (for simple ones). Anyway something up to the developer to decide and not to fix in fpmkunit.

[fpc-pascal] zstream.pp strange dependency?
I have encountered a strange phenomenon, and I would like to fix it, if it weren't for the fact that I have no idea why it appears. So what happened? When using the zstreams.pp unit in a sample project I get an error message "Fatal: Can't find unit FPReadPNG". I searched all sources to find out which one is using the FPReadPNG unit that could be called in return by any unit coming from zstreams, but no success. I'm clueless here. Does anyone have a suggestion where to look, or an explanation why this is happening? Please note that I've been mixing 2.1.1 sources (zipper and zstream) with a 2.0.2 and 2.0.4 compiler. I don't expect that this is the cause of this err message, but perhaps it is. Below is a list of messages I took from the lazarus messages window.

new try)
I would like to declare a polymorph class. The class has several
properties and it's the read and write specifiers that I want to be
virtual abstract. So derived classes override the read and write
specifiers. The problem however is that I get an EAbstractError. The
