| 28 | |
| 29 B<rpmtool> - RPM Auxiliary Tool | |
| 30 | |
| 31 =head1 SYNOPSIS | |
| 32 | |
| 33 B<rpmtool> | |
| 34 I<command> | |
| 35 [I<command-options>] | |
| 36 | |
| 37 =head1 DESCRIPTION | |
| 38 | |
| 39 This is an auxiliary tool to the RedHat Package Manager (RPM). It | |
| 40 provides additional functionality for use in RPM I<spec> files while | |
| 41 building packages. The following I<command>s are available: | |
| 42 | |
| 43 =over 4 | |
| 44 | |
| 45 =item B<platform> | |
| 46 | |
| 47 This command outputs a unique platform id in the format | |
| 48 "<architecture>-<system><release>". For instance, the output on a | |
| 49 FreeBSD platform can be "i386-freebsd4.2", the output on a Linux | |
| 50 platform can be "i686-linux2.2.16", the output on a Solaris platform can | |
| 51 be "sun4u-sunos5.8", etc. | |
| 52 | |
| 53 Example: | |
| 54 | |
| 55 case `rpmtool platform`; in | |
| 56 *-freebsd[34].* ) ... ;; | |
| 57 *-sunos5.[678] ) ... ;; | |
| 58 *-linux2.[24].* ) ... ;; | |
| 59 esac | |
| 60 | |
| 61 =item B<mflags> [B<-O>] I<tool> | |
| 62 | |
| 63 This command outputs additional flags for make(1) for | |
| 64 use with the program I<tool>. It provides only standard flags which | |
| 65 always can be used. In conjunction with B<-O> (optimization), it also provides | |
| 66 reasonable job control for use on multi-processor platforms (for instance it | |
| 67 outputs "-j4" on an SMP system with 2 CPUs if GNU make or BSD pmake is used). | |
| 68 | |
| 69 Example: | |
| 70 | |
| 71 make `rpmtool mflags -O make` | |
| 72 | |
| 73 =item B<cflags> [B<-O>] I<tool> | |
| 74 | |
| 75 This command outputs additional flags for cc(1) for use with the program | |
| 76 I<tool>. It provides only standard flags which always can be used. | |
| 77 conjunction with B<-O> it provides also optimization flags (for instance | |
| 78 it outputs "-O2 -pipe" for GNU C/C++ compiler). | |
| 79 | |
| 80 Example: | |
| 81 | |
| 82 CC="$CC" CFLAGS=`rpmtool cflags -O $CC` ./configure ... | |
| 83 | |
| 84 =item B<cppflags> [B<-p> I<prefix>] [[C<+|->I<subdir> ...] | |
| 85 | |
| 86 This command output cpp(1) C<-I> options for the OpenPKG instance | |
| 87 I<prefix>. It optionally can prefix or suffix with one or more I<subdir> | |
| 88 related options, too. If I<subdir> is prefixed with C<+> (or not | |
| 89 prefixed at all), the generated option is appended. If I<subdir> is | |
| 90 prefixed with C<-> the generated option is prepended. | |
| 91 | |
| 92 Example: | |
| 93 | |
| 94 rpmtool cppflags -p /foo bar -baz +quux | |
| 95 | |
| 96 =item B<ldflags> [B<-p> I<prefix>] [[C<+|->I<subdir> ...] | |
| 97 | |
| 98 This command output ld(1) C<-L> options for the OpenPKG instance | |
| 99 I<prefix>. It optionally can prefix or suffix with one or more I<subdir> | |
| 100 related options, too. If I<subdir> is prefixed with C<+> (or not | |
| 101 prefixed at all), the generated option is appended. If I<subdir> is | |
| 102 prefixed with C<-> the generated option is prepended. | |
| 103 | |
| 104 Example: | |
| 105 | |
| 106 rpmtool ldflags -p /foo bar -baz +quux | |
| 107 | |
| 108 =item B<files> [B<-v>] [B<-o> I<outfile>] [B<-r> I<build-root>] [I<entry> ...] | |
| 109 | |
| 110 This is a dynamic variant of the RPM C<%files> section, i.e., it | |
| 111 dynamically creates the contents of the C<%files> section for use with | |
| 112 the C<%files -f> command. For this the file list entries are read from | |
| 113 the command line (or from stdin if no arguments are given or a single | |
| 114 argument C<-> is given) and written to stdout (if no B<-o> option is | |
| 115 given or its I<outfile> argument is C<->) or to I<outfile>. | |
| 116 | |
| 117 The trick of this approach is to be able to use additional features in | |
| 118 the file list which RPM does not provide. The following features are | |
| 119 provided: | |
| 120 | |
| 121 =over 4 | |
| 122 | |
| 123 =item B<Trailing Tags> | |
| 124 | |
| 125 RPM requires that all tags (like C<%attr(...)> or C<%dir>) preceed the | |
| 126 path in a file list entry. This sometimes leads to ugly and unreadable | |
| 127 file lists, because all paths cannot be left-aligned. With rpmtool(8) | |
| 128 tags in the input file list can be at leading and trailing positions. | |
| 129 The output file list will nevertheless have all tags in leading | |
| 130 positions for RPM. | |
| 131 | |
| 132 =item B<Syntactical Set Pattern> | |
| 133 | |
| 134 RPM supports simple wildcard patterns like C</path/*> or C</path/[a-z]>, | |
| 135 etc. Sometimes it is convenient, to also have (in addition to character | |
| 136 sets) string sets like C</path/{foo,bar,quux}>. rpmtool(8) provides this | |
| 137 by syntactically (without checking the filesystem) expanding those | |
| 138 string sets. | |
| 139 | |
| 140 =item B<Overriding Entries> | |
| 141 | |
| 142 This is the most important feature and the reason why shtool(1)'s | |
| 143 B<files> command was implemented. Although RPM allows one to specify a | |
| 144 directory in a file list and then implicitly expands this recursively | |
| 145 into its contents, it unfortunately does not allow one to later | |
| 146 explcitly override particular entries (usually if an individual | |
| 147 C<%attr(...)> tag is required). rpmtool(8) now supports overriding | |
| 148 entries, i.e., if a path occurs multiple times, only the last occurance | |
| 149 is kept. | |
| 150 | |
| 151 =item B<Negation Tag> | |
| 152 | |
| 153 This provides an additional tag C<%not> which can be used to explicitly | |
| 154 exclude a previously implicitly added entry. | |
| 155 | |
| 156 =back | |
| 157 | |
| 158 Example: | |
| 159 | |
| 160 %install | |
| 161 : | |
| 162 rpmtool files -o files -r$RPM_BUILD_ROOT \ | |
| 163 '%defattr(-,foo,foo)' \ | |
| 164 '%{prefix}' \ | |
| 165 '%attr(1755,root,foo) %{prefix}/bin/bar' \ | |
| 166 '%not %dir {%{prefix},%{prefix}/*,%{prefix}/man/*}' \ | |
| 167 '%not %{prefix}/info/dir' | |
| 168 | |
| 169 %files -f files | |
| 170 | |
| 171 =item B<msg> [B<-b>] | |
| 172 | |
| 173 This displays the contents of F<stdin> as a boxed message. If option | |
| 174 B<-b> is given it additionally beeps once before displaying the box. | |
