Okay, so now we know how to write hello world in C#, compile it and run it. Next, let’s try to automate the build portion a bit. It’s not going to be very much of an improvement to start out with; we’re just replacing the gmcs command with a make command. But it’s laying a framework, so let’s ignore that for the time being.
Get back to the workspace
$ cd ~/src/greeting
Create a simple Makefile
$ cat > Makefile # the first target is the one executed when no target is named all: Greeting.exe #don't do anything # running 'make clean' will execute this target clean: rm Greeting.exe # running 'make Greeting.exe' will execute this target Greeting.exe: Greeting.cs # the same as gmcs -out:Greeting.exe Greeting.cs gmcs -out:$@ $^
Test the Makefile
$ make gmcs -out:Greeting.exe Greeting.cs $ make clean rm Greeting.exe $ make Greeting.exe gmcs -out:Greeting.exe Greeting.cs $ ./Greeting.exe Greetings, World!
We’ll use these short lessons as building blocks for larger tasks, like creating a distribution using automake and autoconf. Baby steps first :)
