No idea, but Python, ruby, lua and php do not generate real programs but instead are just scripts which run in a interpreter, which is immensely different from a real program. A more close comparison to Pascal might be asking what Fortran, Cobol, Ada or other similar compiled languages do, and I think that all of those would need a C interface. I know very well Java due to Android work, which cannot bind to anything directly. It requires a special format using plain procedures in a special way, so it is like a C interface, or a plan Pascal procedural interface.

See compiler/msg/errore.msg. The strange characters at the beginning
specify for which platforms and host operating systems the option is
displayed ("3" = 386 like in ppc386 ;-) ). OS/2 (and EMX) can only
run on x86 (or x86-64 in x86 mode, of course), i.e. that option is
not valid for an x86-64 compiler.

The whole point of asking here is to avoid adding anything obscure.
And the "more strange obscure logic" implies that there is already some
obscure logic.
Where is that?
IMO the compiler help text is obscure since it does not even mention
the -WF option. Should I create a bug report?

The "obscure logic" prevents that -WG is passed to the compiler for

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Are these correct or maybe outdated?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
-WT = {$apptype tool}: only classic Mac OS
{$apptype arm7}, {$apptype arm9}: Only used for Nintendo DS, no command
line switch available
Are they mutually exclusive or can some be paired?
They are mutually exclusive. If there are multiple on the command line
then the last one will win. Also an {$apptype ...} directive in the
project file will win.
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.
Regards,
Sven

[fpc-pascal] Options -WG -WC -WF -WT
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? Are they mutually exclusive or can some be paired? What kind of program is created under Windows without any of these options?

FPC does not (fully) support directly calling external C++ libraries. LibQT4Pas offers a plain C interface to QT for use by FPC.

[fpc-pascal] libQT4Pas - Why it is needed?
Hi, I am wondering. If I build application for linux using gtk2 widgetset for GNOME (or XFCE etc.) and send this program to my friend, then he can run it without any external librarys (of course if he have gnome too), this same thing on windows. But why when I build application on KDE interface I need some external libQT4Pas to run it and my friend need it too (he have KDE so all QT librarys too)? There is no libGTK4Pas so why exists layer libQT4Pas? What is difference between GTK and QT librarys?
