Any problem? Am I missing something?

Are you on Windows? Then you must add "{$apptype console}".

Only on Windows?

Ant?nio

Windows and perhaps OS/2 are the only systems that differentiate between GUI and console applications.

Maybe something could be done to make things easier for Windows users?

Sure, they can move to Linux :)

But you can fill in a bug report and request to add the the templates and IFDEF for windows that add console mode, or something like that

Maybe a "simple console application" project could be added to Lazarus or "{$apptype console}" could be added by default to "custom program" projects.

It will not be changed however, that console I/O is possible without {$apptype console}, because it was only rather recently changed to be this way (because this is how users expect Windows applications to behave).

I think this is a good idea.

{$IFDEF Windows}{$apptype console}{$ENDIF}

These things can be done by the IDE by passing the right -W option. I'm not sure about the details. Some of the -W options have changed. I will ask on the FPC list, when -WG, -WC, -WF, -WT should be passed.

Mattias

Please check Project options / Compiler options / Linking / Target OS specif options.
Make sure the -WG is not checked.

Mattias

You are right, unchecking -WG it is OK.

Mattias:
Could you tell us where we find this in the documentation? I'm sure it's there -- I'd just like to add it to my notes since I'll probably encounter the same problem at some point :-)
Thanks,
Curt Carpenter

You will get this only if you start with an Application and then
decide to do some console stuff.

It's explained in the Lazarus book. The -WG option is explained in the Free Pascal book, the FPC "User's guide", the FAQ and various other places.
I added a hint to the FAQ and the tutorial.

Mattias

manually or automatic? i don't know that i can remember to do this for all the apps that i'm headed towards that i develop and test on winwhatever with the ultimate goal of simply compiling on OS/2 and placing in production... this should not have to be anything manually handled... IMHO of course...

is there now an english translation version available? i know it was discussed some time back but i've not seen anything about its availability since then :?

It was an user error.
You don't need to add the directives.

Yes, the english version is available since aprox. April, last year. In the Lazarus website: http://www.lazarus.freepascal.org/ In the left side there is: "Bookstore Lazarus, the complete guide"
