$ g++ -Wall -c "new.cpp"
$ ls
new.cpp  new.o
$

       -c  Compile or assemble the source files, but do not link.  The linking stage simply is not done.  The
           ultimate output is in the form of an object file for each source file.

           By default, the object file name for a source file is made by replacing the suffix .c, .i, .s,
           etc., with .o.

           Unrecognized input files, not requiring compilation or assembly, are ignored.

$ g++ -Wall  "new.cpp"
$ ls
a.out  new.cpp  new.o
$ ./a.out
Hello World!$
$

$ g++ -Wall  -onew "new.cpp"
$ ls
a.out  new  new.cpp  new.o
$ ./new
Hello World!$
$

А вот при наличии n работает. Получается, каждый вывод на экран нужно заканчивать переводом строки, так?
И еще. А нельзя ли самой Geany указать, какой командой компилировать код? Чтобы через консоль отдельно не работать. В настройках Geany есть пути к утилитам, но там только make, браузер и т. п.

Нашел все-таки, где задаются команды для компиляции/сборки. Меню Сборка — Параметры сборки. Теперь еще вопрос: где задаются пути к библиотекам? Например, пишу #include <cctype> — не видит. Хотя библиотека благополучно лежит в /usr/include/c++/4.4/

• Why do you read only the last line? The dump has the useful information if you read it from the beginning.

I had to «build»/compile it first on geany before I ran the code.

I have put together my first c++ program and after some confusion with the iostream (at first i thought it was isostream…that worked great lol) now everythign compiles great (using geany but compiling from terminal does the same thing) but when i try to run the program, with either ./gameover or executing it with geany, i get error 126, and it tells me that permission is denied. but if i try sudo ./gameover then it tells me «command not found»

here is my program:

// Game Over
// My first C++ Program
#include <iostream>
int main()
{
std::cout << «Game Over!» << std::endl;
return 0;
}

Ok, first of all, there is no reason to use sudo. I would suggest finding a guide highlighting when to use sudo. Using it incorrectly is the easiest way to make your machine no more safe than even Windows.

Okay, now that that is out of the way.

Here is how you use g++

g++ <source-file> -o <executable>

then run the executable by running

./<executable>

The -Wall is merely for the compilation stage that g++ uses. It has no bearing on the linking stage that makes the executable you are trying to run.

I do not use geany… whatever that is… so therefore I cannot comment on that. Do you have any experience using the gnome-terminal? If so, find out what permission are assigned to your executable. Use a command such as:

$ ls -l myExe
and report back.

P.S. -Wall is used to report all warnings that may be generated during compilation of your code.

Found it. I went to Build > Set includes and arguments and there is the option to edit the command it runs to compile it. just took out -Wall so it reads g++ -c «%f» («%f» is replaced by the current filename when it runs) and now my program runs just dandy!

would be curious to know what the -c -o and -Wall options do tho

Ok…

the -c indicates to generate an object file (a .o file) AND not attempt to link to form an executable file.

the -Wall indicates to generate «errors» on all warnings… this will prevent an object file from being generated (I need to verify this!!!)

the -o is used to indicate where to place the results of a compiled program (i.e. where to place the object file), or in the case of linking, where to place the executable file.

P.S. Removing the -Wall should not have prevented you from running the executable unless…

1) The executable was not generated because of one or more «warnings» during compilation

2) Because ‘geany’ is a POS.

I have a similar proble, but when i open the gdb, set the break point and when i type run i get:

Starting program: /media/gaBo/U/IE-1503/Tareas/Tarea 2/A75967tarea2
/bin/bash: /media/gaBo/U/IE-1503/Tareas/Tarea 2/A75967tarea2: Permission denied
/bin/bash: l�nea 0: exec: /media/gaBo/U/IE-1503/Tareas/Tarea 2/A75967tarea2: can’t execute: Permission denied
During startup program exited with code 126.

Same thing when i try to run it. And i get it with every program i compile.. Any help?

You must compile the program from the directory /home….etc, but not from /media
