Hi,
According to fpc -h (2.7.1):
Option -WG creates graphic type application (EMX, OS/2, Windows).
Option -WC creates console type application (EMX, OS/2, Windows).
fpc -h (2.6.1) knows also:
Option -WF creates full screen type application (EMX, OS/2)
And the "user" documentation knows one more:
http://www.freepascal.org/docs-html/user/usersu15.html#x38-450005.1.4
-WT Generate a TOOL application (+) or a console application (-).
Are these correct or maybe outdated?
Here is the complete list of supported apptypes:
-WA = {$apptype native}: currently only used for NativeNT target if a
driver is compiled (not finalized yet, so I wouldn't build on that ;) )
-WC = {$apptype console}: Console application on EMX, OS/2 and Windows
(and according to compiler source also classic Mac OS). On Windows this
means that calling that application from inside e.g. cmd.exe will block
cmd.exe until the application is finished. Calling the application using
the explorer will result in a console window appearing.
-WG = {$apptype gui}: GUI application on EMX, OS/2 and Windows (and
according to compiler source also classic Mac OS).
On Windows this means that e.g. cmd.exe won't block when such an application is
started and on
console window will be shown. Also the Std I/O is closed by the application
-WF = {$apptype fs}: Fullscreen application on EMX and OS/2
For 2.7.1 too?
The option is missing in the ppcx64 -h help.
I took this knowledge from the compiler's source directly, so yes.
What kind of program is created under Windows without any of
these options?
The apptype always (not only Windows) defaults to "Console" except on
WinCE where the default is "GUI".
Note (as I've also read your other mail): I would not suggest to let the
IDE automatically set this based on some obscure logic. The option in
"Project Settings => Compiler Settings => Linking => Target specific
options" is enough.
The "obscure logic" prevents that -WG is passed to the compiler for
invalid targets. Otherwise the compiler stops with an error.
I'm not talking about that specific "obscure logic". I just wanted to
avoid that you add "more strange obscure logic" ;P
If I understand correct, then a Windows application without -WG is
compiled as a console application and a writeln/readln should work.
Right?
This is correct. At least on Win32 and Win64.
Regards,
Sven
