31 <para>
32 <command>&mpc;</command> and <command>&mwc;</command>, the Makefile,
33 Project and Workspace Creator generate platform and compiler specific
34 files to automate the compilation process
35 (e.g. <filename>GNUmakefile</filename>
36 and <filename>Makefile.am</filename>).
37 </para>
38 <para>
39 The most common way to use the Make Project Creator is to run the
40 workspace generator (<command>&mwc;</command>). This script will
41 generate projects and a single workspace that contains the generated
42 projects. If no input
43 <replaceable>FILE</replaceable> (<filename>.mwc</filename> file)
44 is specified, it will recurse into
45 the directory in which the script was started. It looks for
46 <filename>.mpc</filename> files and generates a project or projects
47 for each one found.
48 </para>
49 <para>
50 Most of what is stated about <command>&mwc;</command> applies to
51 <command>&mpc;</command> except that it only generates projects. If an
52 input <replaceable>FILE</replaceable> (<filename>.mpc</filename> file) is
53 not provided, the project creator will attempt to create a default
54 project in the directory from which the script was started.

96 <parameter>dll</parameter>, <parameter>lib</parameter>). You can
97 override the default template input file name with the
98 <parameter>-ti</parameter> option. The file must have a
99 <filename>mpt</filename> extension and must reside within the
100 include search directories. NOTE: the <parameter>lib</parameter>
101 and the <parameter>lib_exe</parameter> template input files are only

188 <para>
189 specifies that only static projects are generated. By default,
190 only dynamic projects will be generated. This parameter was
191 previously <parameter>-static_only</parameter>. Currently,
192 <command>&mpc;</command> only supports generating dynamic projects
193 or static projects, but not both during the same run. To generate
194 them both you must run <command>&mpc;</command> twice, once with the
195 <parameter>-static</parameter> option and once without.
196 Additionally, the <parameter>vc6</parameter>,
197 <parameter>em3</parameter>, <parameter>vc7</parameter>,
198 <parameter>vc71</parameter> and <parameter>vc8</parameter> project
199 names will no longer automatically have
200 <filename>_Static</filename> appended to the project name when
201 generating static projects. This can still be achieved by using the
202 <parameter>-name_modifier</parameter> option.
203 </para>
204 <para>
205 When generating static projects, inter-project dependencies will
206 not be generated for libraries within <parameter>vc6</parameter>,
207 <parameter>em3</parameter>, <parameter>vc7</parameter>,
208 and <parameter>vc71</parameter> workspaces. The reason is due to
209 the fact that each static library that depended upon another would
210 be combined at the library creation stage, resulting in extremely
211 large libraries. Dependencies are handled correctly by vc8 and
212 later. This behavior can be modified by setting the
213 <envar>MPC_DEPENDENCY_COMBINED_STATIC_LIBRARY</envar> environment
214 variable. It will force <command>&mpc;</command> to generate
215 inter-project dependencies for libraries within a single workspace
