certainly, with great pleasure

I'm writing you another note that might be useful. I modified the bash script again like this and it works perfectly:

#!/bin/bash

exec 2>&1
echo -e "Content-type: text/plain\n"
/usr/bin/g++ test.cpp -o test.cgi

so, to compile a c++ program

• it's better to use `/usr/bin/g++`
• it is not necessary to use the "absolute" path, the "relative" one is sufficient, which is simpler and safer, because it does not reveal to the users their chroot in the server system

Greetings

I tried your suggestion literally and got this response in the browser:

then i tried to use `/usr/bin/g++` and it worked great!

thank you for everything (to quote the dolphins=aliens from the "hitchhiker's guide to the galaxy", «thanks for all the fish!») I insisted a little because I had intuition that something was wrong and that it would be useful for you so we have the solution

I had already tried several times and it still doesn't work. For example I also tried `/usr/bin/gcc --help` and the scheduler said it doesn't exist

`/usr/bin/gcc` does not exist "for me", because it is not accessible to me: I cannot access the `/usr/bin/` directory. If in Plesk I click on `/usr/bin/` then I see `/bin/`. I don't have the ability to use `/usr/bin/gcc`

Not yet: as I already said, in fact

Quote

the files in /bin/ and /usr/bin/ are the same

 

which means that

/usr/bin/gcc

also doesn't exist, like all the files that should be in `/usr/bin/`, because instead of `/usr/bin/` I still have `/bin/`

you probably thought I hadn't checked yet and thought everything was fine...

thank you

unfortunately there is another problem: I can't compile it because the compiler is missing. I noticed that a system now appears to be available in the home, but the files in /bin/ and /usr/bin/ are the same. In any case, for example, g++ is missing

I didn't know about the cronjob: I guess it's under "scheduled tasks". Now I try

thank you very much

I compiled test.cgi (c++) on my system: Linux/Devuan amd64

I also wanted to try with a perl script, but it doesn't work.

I set the rights to 755 and wrote the .htaccess file, which didn't exist.

In my system everything works fine

thank you all for your attention, you are very kind

as i wrote, the error_log says:

[Tue May 30 22:19:44.533866 2023] [cgid:error] [pid 22217:tid 139805337741056] [client 151.21.204.48:59042] End of script output before headers: test.cgi

the "test.cgi" file works on my machine: Linux/Devuan + Apache2

dear administrator,
i can't get cgi-bin programs to work.
The link https://z0n1n0z.helioho.st/cgi-bin/test.cgi is a compiled c++ test program. The source code is at https://z0n1n0z.helioho.st/cgi-bin/test.cpp.
https://z0n1n0z.helioho.st/cgi-bin/test.pl doesn't work either. In cgi-bin/ there is also an .htaccess file which contains this:

Options +ExecCGI
AddHandler cgi-script .cgi .pl .py
LimitRequestBody 2147483647

the "error_log" file says:
[Tue May 30 22:19:44.533866 2023] [cgid:error] [pid 22217:tid 139805337741056] [client 151.21.204.48:59042] End of script output before headers: test.cgi

What can I do to activate cgi-bins?
Thanks for the attention
Best regards
