Running a.out on Cygwin
I wrote and compiled a program on a unix machine using g++. Now I copied it over to the machine with the Unix emulator Cygwin. I tried to run it by entering "a.out" in the command prompt but was given:

"bash: a.out: command not found" (without the quotes)

Also worth mentioning is that i downloaded all of the cygwin packages and installed them.

I'm new to cygwin and i'm not sure what commands it uses to run a program, can anyone help?

Thanks,

- hito

First try typing ./a.out

By default, the current directory is not in your path, so you must explicitly tell it a.out is in the current directory.

To see what directories are in your PATH (the directories where your shell will look for the program you specify on the command line) type echo $PATH.

Most likely, the current directory you're in is not included in that path. You must either add the directory you're in to the $PATH variable or precede your program with a period (which represents the current directory).

Thanks for the help, apparently that was the problem at first. Then when I tried to run it, I got a bunch of errors. What I had to do was upload the source file and recompile it. Dunno why, seeing how both are using g++ to compile but that was the issue and it's working 100% perfectly right now.

Thanks again

ok,
However, should I modify the path variable each time I move to another directory or create a new directory to compile and run programs in? There should be a short way to tell the shell that will not require me to modify the PATH each time I change/create directories. For example in school Unix machine this does not happen. I always create new directories and compile and run new programs and I never need to modify the PATH. But when I switch to cygwin the shell does not recognise the executable in a new directory...

You could put "." in your PATH, but that's not a good idea....
What's wrong with having '.' in your $PATH ?
