gcc not working

Paolo Naldini (hattory) said : #2

The right command should be:

gcc neel.c -o neel

If this will not work, please paste your neel.c file.

It looks like you are trying to include "conio.h". This is a Windows-specific header file. You might want to take a look at ncurses.

Jensen Somers (jsomers) said : #4

The command was correct. If -o is not specified the result will be an executable file called 'a.out'.

As stated by Dan Mulvey, you are trying to include a MS Windows specific header file. Since 'conio' does not exist on Linux you need to find another way of achieving the things you want to do which require the 'conio.h' header file.

When in doubt, post the code of your source file here and we might be able to help.

thanks a lot guys but how do i view the a.out file

Dan Mulvey (danmulvey) said : #6

If the compilation fails, there will be no a.out file. First fix the problems with your code; in other words, find a way to do this without including conio.h, and then try compiling again. If your code compiles without error, you will have an a.out file.

arj (arjpandey) said : #7

well my code was compiled. i just wanted to know the command for viewing the a.out file

Best Jensen Somers (jsomers) said : #8

You can run it using the command:
$ ./a.out
