"bash cannot execute binary file"

[Alex]

testing out gcc in mandrake linux 9.1:

make simple hello world program main.c

compile:

gcc -o main main.c

execute:

bash main

and i get the error in the subject... help!

Do you have permission to execute it?

I beleive that you only use "bash filename" when executing a script.

That's the same as putting the #!/bin/bash at the beginning of the script file. (I beleive, never tried to bash filename anything before)


Just do:

./main

If your in the same directory as the executable.

gcc makes compiled binaries executable by default. Just type their path to run them (using "./" if they're in the current directory).

Segmentation Fault? 😉

Try this bash script.

#!/bin/bash

echo '
#include <stdio.h>

main()
{
printf ("Hello World!\n");
}' > ./main.c

gcc -o main ./main.c

./main

Put that script in a plain text file called test.sh

then:

chmod 777 test.sh

./test.sh

hopefully that works.

edit: forgive me for the brain fart. I thought it was funny to write a script that wrote and compiled it's own c program.

The actual c program is:

#include <stdio.h>

main()
{
printf ("Hello World!\n");
}

That should work, is yours different?
