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.<\/p>\n
So, there’s a quick overview of writing a Makefile. If you want to learn all of the nitty-gritty details, I recommend reading the manual<\/a> over at gnu.org<\/a>.<\/p>\n We’ll use these short lessons as building blocks for larger tasks, like creating a distribution using automake and autoconf. Baby steps first :)<\/p>\n\n$<\/b> cd ~\/src\/greeting<\/code><\/p>\nCreate a simple Makefile<\/h3>\n
\r\n$<\/b> cat > Makefile\r\n# the first target is the one executed when no target is named\r\nall: Greeting.exe\r\n#don't do anything\r\n\r\n# running 'make clean' will execute this target\r\nclean:\r\n\trm Greeting.exe\r\n\r\n# running 'make Greeting.exe' will execute this target\r\nGreeting.exe: Greeting.cs\r\n# the same as gmcs -out:Greeting.exe Greeting.cs\r\n\tgmcs -out:$@ $^\r\n<\/pre>\n
Test the Makefile<\/h3>\n
\r\n$<\/b> make\r\ngmcs -out:Greeting.exe Greeting.cs\r\n$<\/b> make clean\r\nrm Greeting.exe\r\n$<\/b> make Greeting.exe\r\ngmcs -out:Greeting.exe Greeting.cs\r\n$<\/b> .\/Greeting.exe \r\nGreetings, World!\r\n<\/pre>\n
Conclusion<\/h3>\n
