| | 1 | == Current status == |
| | 2 | * 8 build systems |
| | 3 | * XCode -> Mac |
| | 4 | * VCProj -> Win, WinCairo |
| | 5 | * CMake -> WinCE, EFL |
| | 6 | * QMake -> Qt |
| | 7 | * MakeFile -> Gtk |
| | 8 | * GYP -> Chromium |
| | 9 | * Android.mk -> Android |
| | 10 | * wx |
| | 11 | * Some of them requiring a special IDE to add a file |
| | 12 | * Adding and removing a file is more and more expensive which hinders refactoring the code |
| | 13 | * As an example, someone removed some empty files lately that were in the tree for years, presumably because of the barrier to removing files |
| | 14 | * Potential unifying systems: CMake, GYP and QMake were mentioned |
| | 15 | |
| | 16 | == GYP == |
| | 17 | * Constraint: people use whatever IDE they currently use (XCode, Visual Studio) |
| | 18 | * CMake vs GYP (http://code.google.com/p/gyp/wiki/GypVsCMake) |
| | 19 | * GYP keeps the look'n'feel of the native build system |
| | 20 | * For example, it is easy to map from GYP to the native system and vice-versa |
| | 21 | * There is currently no tool to propagate native changes back to GYP though |
| | 22 | |
| | 23 | == CMake == |
| | 24 | * Used by several projects |
| | 25 | * However CMake generated files calls back CMake which made some of the Apple people sad |
| | 26 | |
| | 27 | == The current implementation == |
| | 28 | * We had a look at some of the GYP files |
| | 29 | * The current way is sub-optimal as it uses a lot of arcane 'exclude' (this gave rise to a lot of comments) |
| | 30 | * We would need to refactor the way it is done for people to be fine with such a change |
| | 31 | * A one GYP per platform was mentioned (and using some include mechanism) |
| | 32 | |
| | 33 | == Constraints on the build system files == |
| | 34 | * Adding/Removing a file is a rare operation whereas checking out the source is common |
| | 35 | * Thus we should not put a burden on the most common operation |
| | 36 | * There was a discussion about adding the XCode files as we don't want to add another step |
| | 37 | * Also this would introduce some issues with Apple internal build system |
| | 38 | * The tools to generate the native build system should either use XCode or a Makefile on Mac |
| | 39 | |
| | 40 | == Workflow == |
| | 41 | * If we check-in the build files, we have issues with people just doing 'svn up' and building using make or native method |
| | 42 | * There is a cost with this switch and we need to solve them before making the big switch |
| | 43 | |
| | 44 | == Other ports == |
| | 45 | * Qt and Gtk have their own build integration constraint that needs to be captured |
| | 46 | * CMake is used an 'include' system and not an 'exclude' system |
