Thats an easy fix.
using namespace Wt;
as in
http://www.webtoolkit.eu/wt/src/hello
or if you are like me, use Wt:: everywhere.
To tell the truth, I have never read any of the tutorials. I always
found the examples and reference manual more useful and on occasion the
mailing list / forum ;).
I will say that whatever tutorial you are using is massively outdated.
This line won't work anymore (SLOT is long since deprecated):
Button->clicked.connect(SLOT(&appl, Wapplication::quit));
I would use the hello world I linked to as a new starting point.
I haven't worked with building/running the database examples so I am
unsure about your pastebin. Nor have I worked with CMake.
I would also mention that you don't HAVE to name your source files *.C,
*.cpp will work just fine. Though if you prefer *.C then by all means
continue.
I made a note on the forum to check into the tutorials and remove
outdated ones.

Thanks, I've changed all the #include (headers) with the Wt/ prefix.
Unfortunately I'm now getting other errors:

Would you recommend I follow a different "Getting started guide",
because this one is out of date, or would it be fine to continue with
this one?
Please help me by either fixing the small .C program, or recommending
a different guide.
Thanks for all suggestions,

You should
#include<Wt/WApplication>
instead of
#include<WApplication>
Best of luck

Good Morning,
Unfortunately it seems I'm unable to compile, even the simplest of Wt projects.
I'm able to compile all the examples fine (Ubuntu 11.04), however when
I create my own custom-project I run into some problems.
I'm following a tutorial, and here is the very-basic hello_world.C
file catalogue:
#include<WApplication>
#include<WText>
#include<WPushButton>
int wmain(int argc, char **argv) {
WApplication appl(argc, argv);
// Widgets can be added to a parent
// by calling addWidget() ...
appl.root()->addWidget(new Wtext("<h1>Hello, World!</h1>"));
// ... or by specifying a parent at
// construction time
WPushButton *Button = new WPushButton("Quit", appl.root());
Button->clicked.connect(SLOT(&appl, Wapplication::quit));
return appl.exec();
}
My CMakeLists.txt is as follows:
ADD_EXECUTABLE(hello_world.wt hello_world.C)
TARGET_LINK_LIBRARIES(hello_world.wt /usr/include/Wt)
INCLUDE_DIRECTORIES(/usr/include/Wt)
To compile, I run:
~/Wt/examples/hello_world$ g++ -L/usr/lib -lwt -lwthttp hello_world.C
-o hello_world.wt
hello_world.C:1:24: fatal error: WApplication: No such file or directory
compilation terminated
___
(am I meant to run the cmake program first?)
___
Please tell me what I need to do in order to get my custom projects running.
Thank you for all suggestions,
Alec Taylor
PS: I'm also having trouble running the database-backed examples, such
as wt-homepage. Log: http://pastebin.com/5ER5vZBa Error within
Firefox: "??template??"
