[RESOLVED] execve() Exec format error

[Solutioned]

Hello, I'm surprised by the speed of execution of programs in C compared to PHP, so I decided to work with CGI programs.

I did a "Hello, World" and compiled it on Linux, but after uploading to the server, gives me this error.

lscgid: execve():/hsphere/local/home/test/cgi-bin/a.cgi: Exec format error

Here is the source code.

#include <stdio.h>
int main() {
	printf("Content-Type: text/plain;charset=us-ascii\n\n");
	printf("Hello world\n\n");
	return 0;
}

This was compiled under an i5 processor x86-64 Debian distrubution.

Binary build on Debian system may not be compatible with CentOS/Redhat.
You need to compile the binary on the same server.

Is there any way to create binaries that work for all distributions?

Because I have a shared web hosting and have no direct access to compile.

No, clearly

>Because I have a shared web hosting and have no direct access to compile

can you try

gcc -o a.cgi a.c

to create your own a.cgi. maybe most shared web hosting provide gcc nowadays?

Thanks to everyone, the hosting provider gave me the Shell Access and I already compile the program.

You have to compile the binary from a machine with matching OS like the one your hosting company uses.
