cannot execute binary files on MAC terminal

I've used makefile to generate file. gcc -c hello.c -o hello and fixed the permission problem through: chmod a+x ./hello However, when I want to execute "hello" file. ./hello the system told me that "cannot execute binary file" Can someone help me? I am looking forward your reply badly.

Check whether the GCC compiler is installed in your system correctly or not.

gcc -v

Compile your file:

gcc filename.cpp -o any-name

Running your program:

./any-name

As an alternative to compiling and linking at the same time you can use make:

make hello

Note: without the .c extension.

The terminal output should be:

cc     hello.c   -o hello

The -c argument to gcc produces an object file which you later on must link in order to produce an executable. You can not execute the object file you produced.

Instead, to compile and link at the same time, suitable when you only have 1 .c file, do

gcc hello.c -o hello

Or if you want to break it down to separate compilation and linking steps, do

gcc -c hello.c -o hello.o
gcc hello.o -o hello
