C Compiler Will Not Run/Please Help?

Pl3th0r4x · 12-31-2011, 06:20 PM

I know I am new here, but I hope someone can please help me start?

sudo aptitude install build-essential
sudo gedit first.c

Up until this point everything seems fine except when I save it the code I get this report:

Code:

(gedit:2977): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.EDN36V': No such file or directory

(gedit:2977): Gtk-WARNING **: Attempting to set the permissions of `/root/.local/share/recently-used.xbel', but failed: No such file or directory

(gedit:2977): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.KE136V': No such file or directory

(gedit:2977): Gtk-WARNING **: Attempting to set the permissions of `/root/.local/share/recently-used.xbel', but failed: No such file or directory

Following the rest to run the file results:

cc -c first.c

Code:

first.c: In function ‘main’:
first.c:5:7: error: expected ‘;’ before ‘{’ token

cc -o first first.c

Code:

first.c: In function ‘main’:
first.c:5:7: error: expected ‘;’ before ‘{’ token

./first

Code:

bash: ./file: No such file or directory

Output should show as follows

Hello, world

... but it is not.

Also I added

sudo apt-get install gcc build-essential

To install gcc, but I have the same results.

*Notes*

using Ubuntu 11.10

(a) should be harmless. It seems that /root/.local/share/recently-used.xbel or the path to it doesn't exist, though.
(b) you have a syntax error and the compile is failing. It seems you are missing a ;.
(c) of course ./first won't be found, when the compile errored out.

The first, and perhaps best, advice I can give right now would be for you to refrain editing (and compiling) source code as the root user. It is not necessary. Develop s/w using a regular user account. Thus to edit your file, use something like the following (without the sudo!):

Code:

gedit first.c

And then as AlucardZero indicated, your code has a syntax error within it. I would recommend that you correct it. If you have doubts about how to do this, then post your code here within CODE tags so that we can analyze it.

Thanks for the valuable replies.
Here is the code which I did have a syntax error which I have now gotten in order.

Code:

#include <stdio.h>

int main()
{
printf("Hello, world\n");
return 0;
}

"after printf" I had one of these "{" instead of this "("

I do not see where I am missing a colon, and I am not running this in root I do not know why it says, "root/.local/share/recently-used.xbel"

This did give the result

Hello, world

Within my Terminal. Thank you for your time and if you have anything else you would like to share feel free to discuss. I could use all the advice available.
