Permission Denied though my linux chmod has allowed 777

[edcompsci]

I built a simple program on my linux machine following a tutorial and it builds but I don't see why it is getting Permission Denied when I run it even though I chmod'd the whole directory recursively to 777.

Can someone help?

Did you try rebooting your computer?
Or you can lookup how to kill a program on Linux because you can not run a program already running on Windows if the file has a file lock on it. The same is likely true on Linux; but, since the file system is different it might not be true.

Thanks.

to kill linux process (as sudo) you can use

kill [pid]


or

killall [name of program]


or from a ui with system monitor, kill it just like you would in task manager in Windows.


I will see now if there are hanging processes. Thanks again.

[edcompsci]

No there's no running processes still.

I tried even running codeblocks as sudo and still no luck.

I don't think a reboot will help but I may try that later.

[edcompsci]

reboot did nothing.

You might post the run log and maybe someone could see the cause of the problem.

Thank you.  Nothing runs at all on any piece of code I create (making small c programs).  Down where the logs are no run log appears, only a build log, and I am clicking and Build and Run.


Here's some example code, code isn't the issue, because no matter what program I run, the Permission error comes up right away without running anything.

#include <stdio.h>
#include <string.h>

int main()
{
char a;double b;float c;int d;char *aa;char e[5];char *ee;

printf("address of a char example: %p\n",&a);//%p is "placeholder"
printf("address of a double example: %p\n",&b);//addresses are in hex
printf("address of a float example: %p\n",&c);
printf("address of an int example: %p\n",&d);

aa=&a;
printf("address of a char a example: %p\n",&a);
printf("pointer to address of char a example: %p\n",aa);

ee=e;
printf("address of a array e example: %p\n",e);
printf("pointer to address of array e example: %p\n",ee);
printf("address symbol used (optional), array e example: %p\n",&e);
ee=&e[1];
printf("address symbol used for one element, array e example: %p\n",&e[1]);

return (0);
}

It's some kind of configuration, but I haven't pinpointed it. I thought maybe codeblocks had to run as some kind of user and that user had to be in a certain group maybe, but with the linux users command I only see me, no other user.  Then I though well maybe if I do an ls - l that execute and read permissions aren't set on the files, so I set them all to 777 and still no luck.  Now I am thinking that maybe I need to tell codeblocks to allow my username to use it to run programs, but I don't know how I would do that. I clicked around the menus on top a little bit but haven't found anything.

That space in "c programs" is very suspicious... Could you try removing spaces from your path?

[edcompsci]

new path

P.S. Also try executing the compiled binary from the terminal using ./pointers_addressof
I also suspect that "/media/IDE/ProgrammingCode/0._Console/c_programs/pointers_addressof" is a folder, not your executable, in which case "sh" says "Permission denied" to execute a folder.

[edcompsci]

here's my shell settings. Not sure where you entered the xdg-open part.



It isn't trying to execute a folder because all I'm doing is clicking Build and Run.


Sorry, no it's not a folder. At first it was a file that I forgot to put the .c extension on but the I got the same error with the same program with a .c extension, and 5 or more other .c programs all the same error.

I'll try changing the /bin/sh to /bin/bash

I don't see full build log in your posts, please post one.
Also after a build please post the output of "ls -lAtr" in the folder where you expect the executable to be.
The output should look something like the output from Commaster.
You have to have x-es in the permissions for the executable.

[edcompsci]

changing to /bin/bash did nothing. maybe it needs to run in csh.. will try

[edcompsci]

still stuck.
