16. Automated BuildsIntroduction This pattern arises frequently

17. Automated BuildsIntroduction This pattern arises frequently New data collected? Recalculate statistics

18. Automated BuildsIntroduction This pattern arises frequently Source files changed? Recompile program New data collected? Recalculate statistics

20. Automated BuildsIntroduction Hard or impossible to keep track of:

21. Automated BuildsIntroduction Hard or impossible to keep track of: – what depends on what

22. Automated BuildsIntroduction Hard or impossible to keep track of: – what depends on what – what's up-to-date and what isn't

23. Automated BuildsIntroduction Hard or impossible to keep track of: – what depends on what – what's up-to-date and what isn't "Anything worth repeating is worth automating."

24. Automated BuildsIntroduction Hard or impossible to keep track of: – what depends on what – what's up-to-date and what isn't "Anything worth repeating is worth automating." So use a build manager to automate the process

25. Automated BuildsIntroduction Hard or impossible to keep track of: – what depends on what – what's up-to-date and what isn't "Anything worth repeating is worth automating." So use a build manager to automate the process Describe dependencies in a build file

26. Automated BuildsIntroduction Hard or impossible to keep track of: – what depends on what – what's up-to-date and what isn't "Anything worth repeating is worth automating." So use a build manager to automate the process Describe dependencies in a build file Along with commands used to update things

27. Automated BuildsIntroduction Hard or impossible to keep track of: – what depends on what – what's up-to-date and what isn't "Anything worth repeating is worth automating." So use a build manager to automate the process Describe dependencies in a build file Along with commands used to update things Build manager does the rest

28. Automated BuildsIntroduction Most widely used build manager is Make

29. Automated BuildsIntroduction Most widely used build manager is Make Note: "most widely used", not "most popular"

30. Automated BuildsIntroduction Most widely used build manager is Make Note: "most widely used", not "most popular" Invented by a student intern at Bell Labs in 1975

31. Automated BuildsIntroduction Most widely used build manager is Make Note: "most widely used", not "most popular" Invented by a student intern at Bell Labs in 1975 Has grown into a little programming language

32. Automated BuildsIntroduction Most widely used build manager is Make Note: "most widely used", not "most popular" Invented by a student intern at Bell Labs in 1975 Has grown into a little programming language A very cryptic little language, without a debugger...

33. Automated BuildsIntroduction Most widely used build manager is Make Note: "most widely used", not "most popular" Invented by a student intern at Bell Labs in 1975 Has grown into a little programming language A very cryptic little language, without a debugger......that requires an understanding of the Unix shell

34. Automated BuildsIntroduction GNU Make is fast, free, and well-documented

35. Automated BuildsIntroduction GNU Make is fast, free, and well-documented And many other tools know how to work with it

36. Automated BuildsIntroduction GNU Make is fast, free, and well-documented And many other tools know how to work with it Look at basics and a few advanced features

37. Automated BuildsIntroduction GNU Make is fast, free, and well-documented And many other tools know how to work with it Look at basics and a few advanced features Companion lecture explores SCons

38. Automated BuildsIntroduction GNU Make is fast, free, and well-documented And many other tools know how to work with it Look at basics and a few advanced features Companion lecture explores SCons Java users should look at Ant
