51 058b0118 2005-01-03 devnull .SH DESCRIPTION
52 058b0118 2005-01-03 devnull These programs are shell scripts that invoke the appropriate standard tools
53 058b0118 2005-01-03 devnull for the current operating system and architecture.
54 058b0118 2005-01-03 devnull One can use them to write portable recipes for mkfiles.
57 058b0118 2005-01-03 devnull compiles the named C
59 058b0118 2005-01-03 devnull into object files for the current system.
60 c8b6342d 2005-01-13 devnull The system C compiler is invoked with warnings enabled.
63 c8b6342d 2005-01-13 devnull option adds
65 c8b6342d 2005-01-13 devnull to the include path,
68 c8b6342d 2005-01-13 devnull option defines
70 c8b6342d 2005-01-13 devnull in the C preprocessor.
73 c8b6342d 2005-01-13 devnull defines the symbol
74 058b0118 2005-01-03 devnull .B PLAN9PORT
75 c8b6342d 2005-01-13 devnull defined in the C preprocessor and adds
76 058b0118 2005-01-03 devnull .B $PLAN9/include
77 c8b6342d 2005-01-13 devnull to the include path.
80 058b0118 2005-01-03 devnull also defines
81 058b0118 2005-01-03 devnull .B __sun__
82 cb8f7357 2020-01-20 rsc on SunOS systems.
85 058b0118 2005-01-03 devnull assembles the named files into object files for the current system.
86 058b0118 2005-01-03 devnull Unlike some system assemblers, it does
88 058b0118 2005-01-03 devnull promise to run the C preprocessor on the source files.
91 058b0118 2005-01-03 devnull links the named object files and libraries to create the target executable.
94 058b0118 2005-01-03 devnull option specifies that a library named
95 c8b6342d 2005-01-13 devnull .BI lib name .a
96 058b0118 2005-01-03 devnull be found and linked.
99 058b0118 2005-01-03 devnull option adds directories to the library search path.
101 058b0118 2005-01-03 devnull invokes the system linker with
102 058b0118 2005-01-03 devnull .B $PLAN9/lib
103 058b0118 2005-01-03 devnull already on the library search path.
106 c8b6342d 2005-01-13 devnull searches the named objects and libraries for symbols of the form
107 c8b6342d 2005-01-13 devnull .BI __p9l_autolib_ name \fR,
108 c8b6342d 2005-01-13 devnull which it takes as indication that it should link
109 c8b6342d 2005-01-13 devnull .BI $PLAN9/lib/lib name .a
110 c8b6342d 2005-01-13 devnull as well.
111 c8b6342d 2005-01-13 devnull It also examines such libraries to find their own dependencies.
112 c8b6342d 2005-01-13 devnull A single
114 c8b6342d 2005-01-13 devnull option at the beginning of the command line disables this behavior.
115 c8b6342d 2005-01-13 devnull The symbol
116 c8b6342d 2005-01-13 devnull .BI __p9l_autolib_ name
117 c8b6342d 2005-01-13 devnull is added to an object file by the macro
118 c8b6342d 2005-01-13 devnull .B AUTOLIB( name )\fR,
119 c8b6342d 2005-01-13 devnull defined in
120 c8b6342d 2005-01-13 devnull .B <u.h>.
121 c8b6342d 2005-01-13 devnull Header files associated with libraries contain
122 c8b6342d 2005-01-13 devnull .B AUTOLIB
123 c8b6342d 2005-01-13 devnull annotations; ordinary programs need not use them.
124 c8b6342d 2005-01-13 devnull Due to shortcomings in the implementation, a source file may not
125 c8b6342d 2005-01-13 devnull contain the same
126 c8b6342d 2005-01-13 devnull .B AUTOLIB
127 c8b6342d 2005-01-13 devnull statement multiple times.
130 058b0118 2005-01-03 devnull maintains object file archives called libraries.
131 058b0118 2005-01-03 devnull The exact set of valid command keys varies from system to system,
134 058b0118 2005-01-03 devnull always provides the following key characters:
139 058b0118 2005-01-03 devnull from the archive file.
144 058b0118 2005-01-03 devnull in the archive file, or add them if missing.
147 058b0118 2005-01-03 devnull List a table of contents of the archive.
148 058b0118 2005-01-03 devnull If names are given, only those files are listed.
151 058b0118 2005-01-03 devnull Extract the named files.
152 058b0118 2005-01-03 devnull If no names are given, all files in the archive are
153 058b0118 2005-01-03 devnull extracted.
154 058b0118 2005-01-03 devnull In neither case does
156 058b0118 2005-01-03 devnull alter the archive file.
159 058b0118 2005-01-03 devnull Verbose.
160 058b0118 2005-01-03 devnull Give a file-by-file
161 058b0118 2005-01-03 devnull description of the making of a
162 058b0118 2005-01-03 devnull new archive file from the old archive and the constituent files.
165 058b0118 2005-01-03 devnull give a long listing of all information about the files,
166 058b0118 2005-01-03 devnull somewhat like a listing by
167 058b0118 2005-01-03 devnull .IR ls (1),
173 058b0118 2005-01-03 devnull mode uid/gid size date name
177 058b0118 2005-01-03 devnull Normally
179 058b0118 2005-01-03 devnull will create a new archive when
180 058b0118 2005-01-03 devnull .I afile
181 058b0118 2005-01-03 devnull does not exist, and give a warning.
184 058b0118 2005-01-03 devnull discards any old contents and suppresses the warning.
193 058b0118 2005-01-03 devnull is specified,
195 058b0118 2005-01-03 devnull inserts a table of contents, required by the linker, at
196 058b0118 2005-01-03 devnull the front of the library.
197 058b0118 2005-01-03 devnull The table of contents is
198 058b0118 2005-01-03 devnull rebuilt whenever the archive is modified.
