execve is throwing "No such file or directory" for a statically-linked executable

[minhducsun2002]

Running statically compiled C programs failed.

# isolate --run -- "./a" --time=1
execve("./a"): No such file or directory

The source code of the program is a simple while(1){}; wrapped in int main(), compiled with gcc -static -no-pie.

The existence of the a executable in the directory isolate was invoked can be confirmed.

You should place the executable in the sandbox directory instead, that is the directory printed by `isolate --init`.

[minhducsun2002]

I ran the command above from the sandbox directory.

[gollux]

When you mention "sandbox directory", is it the directory printed by "isolate --init"?

[minhducsun2002]

Yes.

[minhducsun2002]

Actually, I ran cd $(isolate --init) though.
(Afterward I can still confirm it's the sandbox directory isolate printed.)

[gollux]

If you still experience the problem, please send me the executable file with which it fails.

[minhducsun2002]

Here I am bundling the source code and the executable itself.
a.zip

/var/local/lib/isolate/0 # isolate --run -- ./a --time=1
execve("./a"): No such file or directory
/var/local/lib/isolate/0 # ls 
a

[gollux]

/var/local/lib/isolate/0 should contain a "box" subdirectory (created by isolate --init), where you should put your executable.

[minhducsun2002]

Okay, problem solved. Thank you very much for your support.

But, however. (You may have seen that the source code contains only an infinite loop.)

# isolate --run -- a --time=1 --wall-time=1

It's there for over 2 seconds.

[gollux]

``` # isolate --run -- a --time=1 --wall-time=1 ```

This passes the options to the executable inside the sandbox. For options to apply to isolate itself, you must specify them before the "--" separator.

[minhducsun2002]

Okay, the program stopped now.

Thank you very much!

I wanted to ask for a long time but it seems like digging through the source code was kinda too tedious. :)

Digging in the manual would suffice ;)

Sorry, my fault. Have a nice day ;)
