Hey not new to programming C++ but new to linux... I'm running mandrake 9.1 and I'm using the KDevelop software. When I make a new file (testing.cpp), enter something simple like:

#include <iostream>

int main()

{
cout << "Linux is cool!";
return 0;
}

It says:

gmake[2]: Entering directory '/home/nyquilpusher/testing/testing' c++ -DHAVE_CONFIG_H -I, -I, -I,, -I/usr/lib/qt3/include -I/usr/X11R6/include -DQT_THREAD_SUPPORT - D_REENTRANT - O2 -O0 -g3 -Wall -fno-exceptions - fno-check-new -c testingdoc.cpp

testingdoc.cpp:27:15: x.h: No such file or directory

gmake[2]: Leaving directory '/home/nyquilpusher/testing/testing'
gmake[2] *** [testingdoc.o] Error 1
gmake[1]: Leaving directory '/home/nyquilpusher/testing'
gmake[1]: *** [all-recursive] Error 1
gmake: *** [all-recursive-am] Error 2
***failed***

Can anyone shed some light on what I need to do to get this program working or any program in general? And when I hit run and assuming everything works, will the program run in the terminal or..?

Thanks for any help

Check your makefile (whether it was hand-written or generated by KDevelop). If you look at the message gmake gives you, it says that it's trying to compile a source file called testingdoc.cpp, then it fails because it can't find the file.

I don't use KDevelop so I can't give any suggestions on how to clean it up. My guess would be that perhaps you started a project, told it the name of the source was testingdoc.cpp, and then later changed your mind, but forgot to tell KDevelop about it. Then again, KDevelop could also just be confused on its own... dunno.

As for how he program will run, yes, I would assume a new terminal will open to execute the code. You might want to add a 'cin >> dummy_char;' line so you can see the output. Again, same disclaimers about KDevelop...

EDIT: Err... I had the whole cin command bacwards originally... oops.

#include <iostream.h> perhaps ?

I agree with Dark_Helmet, though myself don't use Kdevelop either. Probabably you accidentally changed the "file name settings" somewhere. Since the system tries to find testingdoc.cpp while what you have is testing.cpp.

The easier approch: Delete the project and make a new one; put the source file in the project and then build. However, I THINK it is necessary to add "using namespace std;" under #include <iostream>, like this:
#include <iostream>
using namespace std;
....
Other wise you'll get the error like: cout: No resolved symbol.

Please have a try and put the result here.

Did anyone else notice that the line said x.h? Perhaps if the code he is trying to compile is called testing.cpp, there must be a testingdoc.cpp elsewhere that is trying to be compiled, and is failing because the X lib/include paths are not available.. that's my guess, anyway. (=

I just probably realised it had something to do with the random "failed" messages I got on startup.. and on closer inspection when I got o KDevelop Setupd and try to find KDE-Libraries-Doc, it says to please install it. Now how would one go about installing this?

Thanks

KDE Doc is not installed by default if you did not choose to install it for the first time. But I am suspecting whether the problem is caused by this. Since it is Doc file...

Ok, let's take a look. I am wondering if you have indeed installation problem with Kdevelop. Please compile under shell mode.
$:g++ -o testing testing.cpp
and see whether you can compile it. If so, I suggest reinstall the Kdevelop.

Last words: please bare in mind you might have to add "using namespace std" right after the #include macro.

And how would one go about reinstalling KDevelop? It just came on my mandrake 9.1 Cd..

include <iostream>

wtf i think u might wanna try

include <iostream.h>

#include <iostream>
using namespace std;

is the current proper way...

but i doubt that's the problem
