[fpc-pascal] CRT unit and Windows' terminal

2017-10-12 Thread Mr Bee via fpc-pascal 
Hi,

I want to create console app that's using box drawing characters from
unicode. Before CRT unit is used, it's all fine and my program could draw
table beautifully. But once I put CRT unit, those characters became
garbages. But strangely, it's only happen on Windows' terminal (win10). I
tried the same exact program in Mac and Linux, using each CRT unit, and
they all run fine. I need CRT unit to make my console program more
interactive (i.e. cursor positioning, keyboard handling, text coloring,
etc).

So, what's wrong with CRT unit on Windows? Can anybody explain the strange
behaviour and how to solve the problem?

Thank you.

Regards,

[fpc-pascal] Getting reason for failure with SendToRaw()

2017-10-12 Thread James Richters 
I'm using SendToRaw() from a console application to send an email back to 
myself with attachments to aid in technical support.  It always works find when 
I send the mail to myself. I run SendToRaw() a second time with my customers 
email address instead of mine so I can go over things with them, but sometimes 
it fails, but I don't know why.   SendToRaw() returns a true if successful or 
false if it fails, but I don't know the reason for failures.   Is there some 
way to get an error code so I can figure out what's wrong? Or is there a 
better method for sending email that would give me an error code?  I'm running 
from a single thread console application.

James

Reported at https://bugs.freepascal.org/view.php?id=32538. I didn’t say much 
but I think that should be enough.

Thanks.

Wow, okay, that's a nasty one O.o Considering that the "AbstractError" is
in the System unit it's safe to assume that the compiler is getting
confused there.
Would you please open a bug report with this as a full example?

But I'm glad that you found the issue...

Ok did some tests and here’s an example of how to reproduce it. It’s the name 
“system” which is doing it and if I remove that name the error goes away.

type
TAbstractClass = class
function GetLocation (system: TObject): TPoint; virtual; 
abstract;
end;

Thanks that was the tip I needed.  That unit had an abstract method and
after removing it the problem went away.  Are abstract methods broken or
something?


Normally not :)

What Sven wanted to ascertain was why you get this error, which is totally 
abnormal.

Is there anything I can do to track it down? It has been there for 6 months now 
preventing me from upgrading (I was using 3.1.1 until I got this bad version 
and went back to 3.0.2). If I start removing parts of the program piece by

True. And having a general-purpose preprocessor would come in useful anyway.

Fun fact: windres also just calls gcc, which is probably why we deploy it:
   #define DEFAULT_PREPROCESSOR "gcc -E -xc -DRC_INVOKED"

But it would be a replacement of a somewhat obscure dependency (windres seems to
be a crossbinutils thing) with just keeping a standard one.

AbstractError() is the name of the function the compiler uses to replace
abstract methods with (so that they generate an exception when called).
Thus something very strange is going on with your installation :/
