Problem executing my programs

[draco86]

Hi!

If i compile a (correct) suorce code in the terminal using the command: gcc file.c I didn't get any errors but if then I try to execute the program the terminal print "command not found", even if gcc have created the executable file.

Why?

PS: This happened even if i try to execute an Hello world! suorce code!

um, I am not compiling expert but I believe in order to install from source you are suppose to use these 3 commands.

1. configure

2. make

3. make install (I would use checkinstall, this will create a .deb so you can install that, then if you want to remove it you can use synaptic.)

make sure you have the build-essential package first.

check out this thread if you're confussed.

Just a simple question but if you compile your little app like this

Simple Hello World in C (for example saved as hw.c)


#include <stdio.h>

int main (int argc, char * argv[]) {
printf("Hello World\n");
return 0;
}


with the following command



gcc -o hw hw.c


You should be able to execute the file



./hw


By the way, is the file allowed to execute? If not just change the execute bit



chmod +x hw


Hope I could help.

Maybe your current working directory (where your executable is) is not in your PATH. Prefix program name with ./ to tell that it is in current directory:

instead executing myprogram.ext try: ./myprogram.ext

Thanks, I didn't know that I have to write "./" before the name of the executable file.
