Creating a binary file on Ubuntu

I want to create a binary file from a C file using ubuntu. I have done something like: 

gcc -c ArrayError3.c -o ArrayError3.

This creates a file ArrayError3 on my Desktop. When I click on it, ubuntu tells me that there is no application installed for object files. I am very much a newbie to C and linux. Could anyone please advise me on how to solve this issue? Many thanks.

The problem is in

gcc -c

The -c switch makes GCC not link your code to an actual executable, only compiles it to an object file, which is not a "complete" format, it can't yet be run. Use just

gcc ArrayError3.c -o ArrayError3

instead.

You need to read more about what the arguments for GCC mean. The -c option tells GCC to create an object file, not an executable file. This object file needs to be linked to create an executable file.

This is commonly used when you have several source files that needs to be linked together to form one executable. Example:

$ gcc source1.c -c -o source1.o
$ gcc source2.c -c -o source2.o
$ gcc source1.o source2.o -o exec

The solution for you it to simply not use the -c option.

Just drop the -c so it won't stop after making the object file. The -c option tells gcc not to run the linker. If omit it, gcc will make a full blown executable for you.
