Can't run compiled c-programs in linux mint

Hi.

I'm having problems running a c program I made after compiling.

What happens is this:

$ gcc filename.c -o filename
$ filename
filename: command not found

So the code compiles, and everything seems to be fine. But for some reason i can't run the program afterwards. I guess there's some sort of package i haven't installed, but I can't figure out which. Can anyone help me?

you need to call a program with the directory it is in. In your example you would have to type
./filename
if the program is located in a subdirectory you can do
subdir/filename
and so on.

Ah, thanks. That explains it. I'm used to work on computers where this is not necessary, as long as I'm in the correct foldet.

I'm in the correct directory so I'm not sure what the problem is...

I'm using a linux virtual machine, and I'm not sure if that has anything to do with it, maybe theres some set-up I have failed to do, but down to business.

I am able to compile the program, price.c, and the computer makes "price". If I try to run the program by typing "price" into the terminal I get the error

No command 'price' found, did you mean:
Command 'prime' from package 'prime' (universe)
price: command not found

The weird thing is that the program has worked before on other linux machines. Really confused.

Thank you.

So, did you read the thread you brought back from the dead and posted in? Generally in linux, . is not in your path. You need to explicitly say ./price, not just price.

Seriously, tabstop. What the hell, right?

Right my bad guys. Thanks for the help.

On some systems, "." might be included in the path, "." being your present working directory.

You can append it to your current search path by using

Code:

---

export PATH=$PATH:.

---

And insert it into your ~/.bash_profile or ~/.bashrc file
.bash_profile vs .bashrc

Next time you log in, the new PATH will be used.
