1 | 1 | Chris Cannam | h1. OS/X version, hardware platform, and Qt version compatibility |
---|---|---|---|

3 | 4 | Chris Cannam | Executive summary: For a program like EasyHg that demands the widest possible compatibility, we currently want to build for 10.4 PPC and Intel 32-bit, 10.5 Intel 32-bit, 10.6 Intel 32- and 64-bit. We can't get away with proposing EasyHg for a project if even one project member can't use it. |

5 | 2 | Chris Cannam | To do this, we need at least two builds of Qt: a Carbon build for PPC and i386 on 10.4 using gcc-4.0, and a Cocoa build for x86_64 (and optionally i386) on 10.5+. |

9 | 1 | Chris Cannam | h3. As target |
10 | 1 | Chris Cannam | |
11 | 4 | 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 |
12 | 1 | Chris Cannam | * Appears in PPC and i386 systems |
13 | 1 | Chris Cannam | * Runs in 32-bit mode only |
14 | 1 | Chris Cannam | * Can build for it from 10.4, 10.5, 10.6 |
15 | 1 | Chris Cannam | * Requires SDK @/Developer/SDKs/MacOSX10.4u.SDK@ |
16 | 1 | Chris Cannam | * Requires @-mmacosx-version-min=10.4@ on 10.5+ |
17 | 1 | Chris Cannam | * Requires gcc-4.0 to be requested explicitly on 10.6 |
18 | 1 | Chris Cannam | * Does not support Objective-C 2.0 |
19 | 1 | Chris Cannam | * Not a supported target for Qt's Cocoa builds, Qt Carbon needed |
20 | 1 | Chris Cannam | |
21 | 1 | Chris Cannam | h3. As build host |
22 | 1 | Chris Cannam | |
23 | 1 | Chris Cannam | * Does not support Objective-C 2.0 |
24 | 3 | 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 |

28 | 1 | Chris Cannam | h3. As target |
29 | 1 | Chris Cannam | |
30 | 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 |
31 | 1 | Chris Cannam | * Last version supported for PPC platforms |
32 | 1 | Chris Cannam | * Runs in 32-bit mode by default |
33 | 1 | Chris Cannam | * Can build for it from 10.5, 10.6 |
34 | 1 | Chris Cannam | * Requires SDK @/Developer/SDKs/MacOSX10.5.SDK@ |
35 | 1 | Chris Cannam | * First version to support Objective-C 2.0 |
36 | 1 | Chris Cannam | * Qt Cocoa supported |
37 | 1 | Chris Cannam | |
38 | 1 | Chris Cannam | h3. As build host |
39 | 1 | Chris Cannam | |
40 | 1 | Chris Cannam | * Builds 32-bit by default |
41 | 1 | Chris Cannam | * Can be used to do 64-bit builds |
42 | 1 | Chris Cannam | |
43 | 1 | Chris Cannam | h2. OS/X 10.6 |
44 | 1 | Chris Cannam | |
45 | 1 | Chris Cannam | h3. As target |

49 | 1 | Chris Cannam | * Runs in 64-bit mode by default where possible |
50 | 1 | Chris Cannam | * Is _not_ always 64-bit -- it is supported on 32-bit-only hardware such as Core Duo (first Intel Macs) |
51 | 2 | Chris Cannam | |
52 | 2 | Chris Cannam | h3. As build host |
53 | 2 | Chris Cannam | |
