GCC/C Compiler

How can I include ./ in .bashrc, I mean how does that line look like can you help me ? Thanks

I've noticed several threads asking the same question, however they all have the same answer...

There is no way to include ' . ' as a folder along your search path. It is a Unix built-in and the shell script wouldn't know how to handle it. The best I can sugest is that if you have a folder you tend to write all your programs in, add that to your search path.

Though you could throw your home directory in there for good measure.

Actually, it is possible to include '.' in your path. Simply add a line like:

PATH=$PATH:.

to your ~/.profile

Now, next time you log in, the current directory will be part of your PATH.
There are various reasons why this is not a very good idea though.

Add the following lines in .bashrc

PATH=$PATH:.
export PATH


Then, you can just give the command,

a.out

without the "./"

I just picked up a book on C++.
I've successfully installed the build essential.

No Luck in creating a.out

any ideas???

[kjohri]

Try
g++ hello.cpp

Thanks
Worked perfectly

Just to insure clarity for anyone who may be following along.

I had previously tried the compiler name g++ unsuccessfully.

It is now successful after installing the build-essential package mentioned earlier in this thread.

Again- a problem solved that had been much more difficult than it was supposed to be. Believe it or not, I'd been banging my head trying to find the right alternate name for the compiler. I just hadn't tried the obvious. If I had paid more attention to the chronology of my attempts, I my not have suffered this ordeal.
This is a basic error I've I've made before on other topics.


Thank you Kjohri for saving me much time & aggravation.
