13 =head1 common.mmh and platform.mmh Syntax |
|
14 |
|
15 The fshell build system uses a number of macros to control what should be built and how. These are defined in F<fshell/build/common/common.mmh> and F<fshell/platforms/E<lt>PLATFORME<gt>/platform.mmh>. Each platform defines the things it does and doesn't support in its platform.mmh. common.mmh takes these and defines some derived macros. This system allows fshell to be built in a large number of configurations, ranging from minimal base textshell on Symbian OS v9.1 to full GUI on the latest Symbian Foundation codeline. |
|
16 |
|
17 Any code wishing to use the fshell conditional system should C<< #include <fshell/common.mmh> >> and use the macros below and/or the ones defined in common.mmh to decide how to behave. Below follows the complete list of things that the platform.mmh can define. This isn't the complete list of all the macros that can be I<used>, for that see common.mmh directly. common.mmh can be included anywhere that the preprocessor is used - eg in source code, MMP files, RSS files or bld.infs. |
|
18 |
|
19 The macros that have a [NO_] in are assumed to be supported unless the [NO_] variant is defined. Eg in your MMP file you would check for btrace support with C<#ifdef FSHELL_BTRACE_SUPPORT> and to say a platform didn't support it you'd add C<#define FSHELL_NO_BTRACE_SUPPORT> to the platform.mmh. Unless the platform.mmh says otherwise, common.mmh would define C<FSHELL_BTRACE_SUPPORT>. Everything in fshell that uses btrace checks for C<FSHELL_SUPPORT_BTRACE> in either the bld.inf (in the case of a command that shouldn't be built at all if btrace isn't available) or in its MMP and/or source code (for a command that can still offer some functionality when btrace isn't available). |

23 =over 4 |
|
24 |
|
25 =item FSHELL_[NO_]BTRACE_SUPPORT |
|
26 |
|
27 BTrace (including timestamp2) supported in kernel. |
|
28 |
|
29 =item FSHELL_[NO_]PIPS_SUPPORT |
|
30 |
|
31 Pips runtime available. |
|
32 |
|
33 =item FSHELL_[NO_]PATCHABLE_CONSTANTS_SUPPORT |
|
34 |
|
35 Platform/toolchain supports patchdata. Everything since about Symbian OS v9.1 does therefore it is assumed to be supported by default. |
|
36 |
|
37 =item FSHELL_[NO_]DYNAMICDFC_SUPPORT |
|
38 |
|
39 Kern::DynamicDfcQCreate API is present. Also used to guard TDfc::RawAdd. |
|
40 |
|
41 =item FSHELL_REPLACE_ECONS |
|
42 |
|
43 buildrom macro (on platforms that support it) to say that iosrv should replace econs.DLL with its own implementation. |
|
44 |
|
45 =item FSHELL_PLATFORM_S60 |
|
46 |
|
47 S60 platform (value of this is either 3 or 5, for 3rd edition or 5th edition, or > 5 for foundation). Various UI code uses this to decide whether to build or not. |
|
48 |
|
49 =item FSHELL_PLATFORM_FOUNDATION |
|
50 |
|
51 Symbian Foundation platform (value of this is n, where n is Symbian^n). |
|
52 |
|
53 =item FSHELL_PLATFORM_SYMTB |
|
54 |
|
55 Symbian Timebox release (value can be 92 or 101). |
|
56 |
|
57 =item FSHELL_9_1_SUPPORT |
|
58 |
|
59 Used to guard things that don't work in Symbian OS v9.1, that don't have their own macro. Its use is discouraged in any new code. Currently guards: switchview missing API; missing thread priorities; demand paging definitions; missing RFs API; kernel TFindHandle class. |
|
60 |
|
61 =item FSHELL_CAP_ALL |
|
62 |
|
63 All capabilities are available (platform.mmh must define either this macro or the specific C<FSHELL_CAP_xxx> that are supported) |
|
64 |

65 =item FSHELL_PROTECTED_UIDS |
|
66 |
|
67 Protected uids (0x10xxxxxx) should be used, as opposed to unprotected (0xE0xxxxxx), for exe and dll UID3. The UIDs themselves are all defined at the bottom of common.mmh so nothing else uses this macro directly. Unprotected UIDs should only be specified if the platform produces an unsigned sis file. |
|
68 |
|
69 =item FSHELL_BASE_ROM |
|
70 |
|
71 Configure IBYs for base 'rom' command rather than 'buildrom' style. |

75 ESock and C32 are available. |

|
100 |
|
101 =item FSHELL_[NO_]WSERV2_SUPPORT |
|
102 |
|
103 Windowserver v2 is being used. Very few things need to know what windowserver version is in use, but occasionally it is needed. |

200 |
|
201 =item FSHELL_FLEXIBLEMM_AWARE |
|
202 |
|
203 Indicates that the baseline is recent enough to be aware of the flexible memory model. It doesn't necessarily mean that the flexible model is actually the one being used. It generally guards kernel APIs that weren't introduced until the FMM was (such as Kern::ChunkUserBase). |
|
204 |
|
205 =item FSHELL_SPCRE_SUPPORT |
|
206 |

|
230 |
|
231 An example platform.mmh is included below. This is for an imaginary platform based on the S^4 release, that is text-only but supports most other things. Generally the older and/or more restricted the platform is, the more C<FSHELL_NO_...> macros you have to define. |
