6 Clownfish::Docs::BuildingProjects - Building Apache Clownfish projects
7 in C environments
8
10 The following steps are required to build a project that uses Apache
11 Clownfish:
12
13 · Run the "cfc" command-line application (Clownfish compiler) to
14 generate C headers, C source files, and documentation.
15
16 · Include the C headers generated by the Clownfish compiler in your
17 own code to work with Clownfish objects.
18
19 · Compile an additional C source file generated by CFC.
20
21 · Link your object code, the object code from the generated file, and
22 the Clownfish runtime library.
23
24 Running cfc
25 cfc [--source=<dir>] [--include=<dir>] [--parcel=<name>]
26 --dest=<dir>
27 [--header=<file>] [--footer=<file>]
28
29 Xsource
30
31 Every "--source" argument adds a directory to the list of source
32 directories to search for source parcels. For every source parcel
33 found, CFC generates C headers, a C source file, and documentation.
34
35 The source directories are scanned for Clownfish parcel definitions
36 (".cfp"), Clownfish headers (".cfh"), and standalone documentation in
37 Markdown format (".md").
38
39 This option may be specified multiple times.
40
41 Xinclude
42
43 Every "--include" argument adds a directory to the list of include
44 directories. CFC generates C headers for parcels from an include
45 directory only if theyXre required by a source parcel or if theyXre
46 specified with the "--parcel" option. Only C headers are generated for
47 included parcels, no C source code or documentation.
48
49 The include directories are scanned for Clownfish parcel definitions
50 (".cfp") and Clownfish headers (".cfh").
51
52 After the directories specified on the command-line, the following
53 directories are processed:
54
55 · Directories from the environment variable "CLOWNFISH_INCLUDE".
56 This variable contains a colon-separated list of directories.
57
58 · On UNIX-like systems "/usr/local/share/clownfish/include" and
59 "/usr/share/clownfish/include".
60
61 This option may be specified multiple times.
62
63 Xparcel
64
65 Adds a parcel to the list of prerequisite parcels to make sure that its
66 C headers are generated. This is useful when running without the
67 "--source" option. For example, a project that doesnXt define its own
68 Clownfish classes can generate the C headers for the Clownfish runtime
69 with:
70
71 cfc --parcel=Clownfish --dest=autogen
72
73 This option may be specified multiple times.
74
75 Xdest
76
77 The destination directory for generated files. By convention, the name
78 "autogen" is used.
79
80 CFC creates the following subdirectories in the destination directory:
81
82 · "include" contains generated C headers.
83
84 · "sources" contains generated C source files.
85
86 · "man" contains generated man pages.
87
88 · "share/doc/clownfish" contains generated HTML documentation.
89
90 This option is required.
91
92 Xheader
93
94 Specifies a file whose contents are added as a comment on top of each
95 generated file.
96
97 Xfooter
98
99 Specifies a file whose contents are added as a comment on the bottom of
100 each generated file.
101
102 Including the generated C headers
103 The C header files generated with "cfc" can be found in
104 "autogen/include". You should add this directory to your compilerXs
105 search path, for example using "-Iautogen/include" under GCC.
106
107 One C header file is generated for every Clownfish header (.cfh) file.
108 C code that makes use of a class defined in the .cfh file must include
109 the respective C header. The Clownfish compiler also creates a few
110 other internal C header files.
111
112 Compiling the generated source files
113 "cfc" creates one source file for every parcel in
114 "autogen/sources/{parcel_nick}_parcel.c". These files must be compiled
115 with "autogen/include" added to the header search path.
116
117 Linking
118 When linking, add the object files of the CFC-generated code created in
119 the previous step. You must also link the shared library of the
120 Clownfish runtime ("-lclownfish" under GCC).
