在 Linux 终端中编译 C 代码

Question

I am using Linux mint 16. I had a code that I change it a bit. I use two following commands in terminal in order to run the code. The problem is that it does not give me any error but the changes are not applied, which means it runs the previous version of code.

gcc -std=c99 -c Code.c -o Code.o
./Code

Answer 1

gcc -std=c99 -c Code.c -o Code.o will put the compiled object file in Code.o , not ./Code as you expect it to be..

Also, -c tells do not run the linker. So effectively you end up with an object file which cannot be run.

gcc -std=c99 Code.c -o Code will produce what you need.

For a complete list of gcc flags either use man gcc or see http://linux.die.net/man/1/gcc

Answer 2

Try

gcc -std=c99 -c Code.c -o Code
./Code
