| 1 | 1 | Chris Cannam | h1. OS/X version, hardware platform, and Qt version compatibility |
|---|---|---|---|
| 2 | 1 | Chris Cannam | |
| 3 | 6 | Chris Cannam | *Executive summary:* For a program like EasyHg that demands the widest possible compatibility, we currently want to hit the following targets: |
| 4 | 6 | Chris Cannam | |
| 5 | 6 | Chris Cannam | * 10.4 PPC 32-bit Carbon |
| 6 | 6 | Chris Cannam | * 10.4 Intel 32-bit Carbon |
| 7 | 6 | Chris Cannam | * 10.6 Intel 64-bit Cocoa |
| 8 | 1 | Chris Cannam | |
| 9 | 8 | Chris Cannam | To do this, we currently need at least two builds of Qt: |
| 10 | 8 | Chris Cannam | |
| 11 | 9 | Chris Cannam | * 10.5 or 10.6 gcc-4.2 Cocoa x86_64 and optionally i386 |
| 12 | 8 | Chris Cannam | * 10.4 gcc-4.0 Carbon PPC and i386 |
| 13 | 1 | Chris Cannam | |
| 14 | 9 | Chris Cannam | This currently means the Qt 4.7.1 default distribution plus a separate Carbon build will do. |
| 15 | 9 | Chris Cannam | |
| 16 | 9 | Chris Cannam | Note it is not possible to cover all platforms in a single build step, we always need to do at least two separate builds plus lipo. |

| 18 | 5 | Chris Cannam | h2. OS/X 10.6 |
| 19 | 5 | Chris Cannam | |
| 20 | 1 | Chris Cannam | h3. As target |
| 21 | 1 | Chris Cannam | |
| 22 | 11 | Chris Cannam | * By far the most common version as of Feb 2011 (apparently >80%) |
| 23 | 5 | Chris Cannam | * Not supported on PPC |
| 24 | 5 | Chris Cannam | * Runs in 64-bit mode by default where possible |
| 25 | 10 | Chris Cannam | * Note Python is also 64-bit by default, so PyQt needs to be as well |
| 26 | 5 | Chris Cannam | * Is _not_ always 64-bit -- it is supported on 32-bit-only hardware such as Core Duo (first Intel Macs) |
| 27 | 1 | Chris Cannam | |
| 28 | 1 | Chris Cannam | h3. As build host |
| 29 | 1 | Chris Cannam | |
| 30 | 5 | Chris Cannam | * Builds 64-bit by default |
| 31 | 5 | Chris Cannam | * Can be used to do 32-bit Intel and PPC builds |
| 32 | 1 | Chris Cannam | |
| 33 | 1 | Chris Cannam | h2. OS/X 10.5 |
| 34 | 1 | Chris Cannam | |
| 35 | 1 | Chris Cannam | h3. As target |
| 36 | 1 | Chris Cannam | |
| 37 | 2 | Chris Cannam | * Not all that much more widely used than 10.4 -- if we were dropping 10.4, we probably might as well drop 10.5 as well |
| 38 | 1 | Chris Cannam | * Last version supported for PPC platforms |
| 39 | 1 | Chris Cannam | * Runs in 32-bit mode by default |
| 40 | 1 | Chris Cannam | * Can build for it from 10.5, 10.6 |
| 41 | 1 | Chris Cannam | * Requires SDK @/Developer/SDKs/MacOSX10.5.SDK@ |
| 42 | 1 | Chris Cannam | * First version to support Objective-C 2.0 |
| 43 | 1 | Chris Cannam | * Qt Cocoa supported |
| 44 | 1 | Chris Cannam | |
| 45 | 1 | Chris Cannam | h3. As build host |
| 46 | 1 | Chris Cannam | |
| 47 | 1 | Chris Cannam | * Builds 32-bit by default |
| 48 | 1 | Chris Cannam | * Can be used to do 64-bit builds |
| 49 | 1 | Chris Cannam | |
| 50 | 5 | Chris Cannam | h2. OS/X 10.4 |
| 51 | 1 | Chris Cannam | |
| 52 | 1 | Chris Cannam | h3. As target |
| 53 | 1 | Chris Cannam | |
| 54 | 5 | Chris Cannam | * Oldest version still apparently in use as of Feb 2011: not very widespread (low single digit %age of Mac users), but at least two researchers here use it |
| 55 | 5 | Chris Cannam | * Appears in PPC and i386 systems |
| 56 | 5 | Chris Cannam | * Runs in 32-bit mode only |
| 57 | 5 | Chris Cannam | * Can build for it from 10.4, 10.5, 10.6 |
| 58 | 5 | Chris Cannam | * Requires SDK @/Developer/SDKs/MacOSX10.4u.SDK@ |
| 59 | 5 | Chris Cannam | * Requires @-mmacosx-version-min=10.4@ on 10.5+ |
| 60 | 5 | Chris Cannam | * Requires gcc-4.0 to be requested explicitly on 10.6 |
| 61 | 5 | Chris Cannam | * Does not support Objective-C 2.0 |
| 62 | 5 | Chris Cannam | * Not a supported target for Qt's Cocoa builds, Qt Carbon needed |
| 63 | 2 | Chris Cannam | |
| 64 | 2 | Chris Cannam | h3. As build host |
| 65 | 2 | Chris Cannam | |
| 66 | 5 | Chris Cannam | * Does not support Objective-C 2.0 |
| 67 | 5 | Chris Cannam | * 10.4u SDK can be used to build 64-bit executables of simple C/C++ programs such as plugins, but not of GUIs or anything using Core frameworks |
