Ubuntu Manpage: mpc-ace, mwc-ace — generate project and workspace files

NAME

       mpc-ace, mwc-ace — generate project and workspace files

SYNOPSIS

       mpc-ace [OPTION ...]  [FILE ...]

       mwc-ace [OPTION ...]  [FILE ...]

DESCRIPTION

mpc-ace and mwc-ace, the Makefile, Project and Workspace Creator generate platform and compiler specific
files to automate the compilation process (e.g. GNUmakefile and Makefile.am).

The most common way to use the Make Project Creator is to run the workspace generator (mwc-ace). This
script will generate projects and a single workspace that contains the generated projects. If no input
FILE (.mwc file) is specified, it will recurse into the directory in which the script was started. It
looks for .mpc files and generates a project or projects for each one found.

Most of what is stated about mwc-ace applies to mpc-ace except that it only generates projects. If an
input FILE (.mpc file) is not provided, the project creator will attempt to create a default project in
the directory from which the script was started.

-global file
specifies the global input file. Values stored within this file are applied to all projects.
If not specified, defaults to config/global.mpb

-include directory
specifies a directory to search when looking for base projects, template input files and
templates. This option can be used multiple times to add directories. Two include directories
are used by default (config and templates)

-recurse recurse from the current directory and generate from all found input files.

-ti dll | lib | dll_exe | lib_exe:file
specifies the template input file (with no extension) for the specific type, e.g. -ti
dll_exe:vc8exe. Each project creator has a default template input file for each type of
project (dll_exe, lib_exe, dll, lib). You can override the default template input file name
with the -ti option. The file must have a mpt extension and must reside within the include
search directories. NOTE: the lib and the lib_exe template input files are only used
when MPC is generating static projects

-hierarchy
generate a workspace in a hierarchical fashion. Forces the generation of a hierarchical
workspace at each directory level in between the toplevel directory and the location of the
.mpc file that is being processed. This is the default for make based workspace creators.
NOTE: This option has no effect when when used with mpc-ace

-template file
specifies the template name (with no extension). file should have a .mpd extension and sit in
one of the include search directories. NOTE: The -template option overrides the template
file for all types specified

-relative name=var
any $() variable in an mpc file that is matched to name is replaced by var only if var can be
made into a relative path based on the current working directory

-base project
add project as a base project to each generated project file. Do not provide a file extension,
the .mpb extension will be tried first; if that fails the .mpc extension will be tried

-nocomments
do not place comments in the generated files

-noreldefs
do not try to generate default relative definitions for *_ROOT, which come from environment
variables

-notoplevel
do not generate the top level target file. Files are still processed, but no top level file is
created. For mwc-ace, it says process all projects for a workspace, but do not generate the
top level workspace file. For mpc-ace, it says process the .mpc files, but do not generate the
project files

-static specifies that only static projects are generated. By default, only dynamic projects will be
generated. This parameter was previously -static_only. Currently, mpc-ace only supports
generating dynamic projects or static projects, but not both during the same run. To generate
them both you must run mpc-ace twice, once with the -static option and once without.
Additionally, the vc6, em3, vc7, vc71 and vc8 project names will no longer automatically have
_Static appended to the project name when generating static projects. This can still be
achieved by using the -name_modifier option.

When generating static projects, inter-project dependencies will not be generated for libraries
within vc6, em3, vc7, and vc71 workspaces. The reason is due to the fact that each static
library that depended upon another would be combined at the library creation stage, resulting
in extremely large libraries. Dependencies are handled correctly by vc8 and later. This
behavior can be modified by setting the MPC_DEPENDENCY_COMBINED_STATIC_LIBRARY environment
variable. It will force mpc-ace to generate inter-project dependencies for libraries within a
single workspace

-genins generate .ins files after processing each project that can be used in conjunction with the
prj_install.pl script to install different parts of the project (such as header files) into an
alternate location

-use_env use environment variables for all uses of $() instead of the relative replacement values

-value_template name+=val | name=val | name-=val
this option allows modification of a template input name pair. Use += to add val to the name's
value. Use -= to subtract and = to override the value. If a template variable value will
contain spaces, it is best to enclose the whole setting in double quotes and use single quotes
within the value to retain spaces (if it is necessary)

-value_project name+=val | name=val | name-=val
this option allows modification of a project variable assignment. Use += to add val to the
name's value. Use -= to subtract and = to override the value. This can be used to introduce
new name value pairs to a project. However, it must be a valid project assignment

-make_coexistence
if multiple make based project types are generated, they will be named such that they can
coexist

-feature_file file
specifies the features file to read before processing. These feature names can be anything,
but they should correspond to values used for the requires and avoids keywords. If a feature
is required and is not enabled then the project will not be created. If a feature is to be
avoided and it is enabled then the project will not be created. The default feature file is
default.features under the config directory

-expand_vars
perform direct expansion, instead of performing relative replacement with either -use_env or
-relative options

-features features
specifies the feature list to set before processing. Values specified by this option overwrite
values from features files, e.g. -features "qos=1,ssl=0"

-gendot generate .dot files for use with Graphvis. This option, which is only useful with mwc-ace,
will result in the generation of .dot files for each workspace processed. Each .dot file will
contain information that can be fed to Graphvis to display the dependency information for the
various projects found within the workspace.

-exclude directories
use this option to exclude directories or files when searching for input files. NOTE: This
option has no effect when used with mpc-ace

-name_modifier pattern
modify generated workspace or project names. The pattern passed to this parameter will have
the * portion replaced with the actual output name. For example -name_modifier '*_Static' will
result in all workspace and project names ending in _Static, e.g. FOO_Static.dsw and
FOO_Static.dsp

-apply_project
when used in conjunction with -name_modifier, it applies the name modifier to the project name
also. NOTE: this option has no effect without the -name_modifier option

-workers Specifies number of child processes to use to generate projects.

-workers_dir
The directory for storing temporary output files from the child processes. The default is
'/tmp/mpc' If neither -workers_dir nor -workers_port is used, -workers_dir is assumed.

-workers_port
The port number for the parent listener.

-version print the MPC version and exit

-into directory
place all output files in a mirrored directory structure starting at directory

-gfeature_file file
specifies the global feature file. The default value is global.features under the config
directory

-language cplusplus | csharp | java | vb
specify the language preference. The default is cplusplus

-type automake | bcb2007 | bcb2009 | bds4 | bmake | cc | em3 | ghs | html | make | nmake | sle | vc6 |
vc7 | vc71 | vc8 | vc9 | vc10 | wb26
specifies the type of project file to generate. This option can be used multiple times to
generate multiple types. There is no longer a default. NOTE: The -ti option overrides the
template input file for all types specified

MPC Codebase Configuration File
This configuration file can be used to specify alternate locations for the MPC Configuration File. If a
base.cfg is found underneath the 'config' directory where MPC is executed, it will be read to determine
the location of MPC.cfg based on the directory in which MPC was started.

For example, if $MPC_ROOT/mwc-ace is run under /foo/bar_root/src and $MPC_ROOT/config/base.cfg contained:

/foo/bar_root = /foo/bar_root/MPC/config

MPC would attempt to open and read /foo/bar_root/MPC/config/MPC.cfg as the MPC Configuration File. If
the base configuration file is not present, MPC will try to use $MPC_ROOT/config/MPC.cfg as the MPC
Configuration File.

You may reference environment variables, accessed by $NAME, on either side of the equals sign.

MPC Configuration File
In an effort to move away from the use of environment variables, a configuration file has been
introduced. The configuration file (MPC.cfg) can contain settings to provide command line options,
control logging and direct MPC to dynamic project types.

The following keywords are allowed in the configuration file, which will be read from the 'config'
directory of MPC.

command_line
provide additional command line options to MPC. The value of this setting will be prepended to
the options passed to mwc-ace or mpc-ace

default_type
provide a single project type (as specified by the -type option) as the default project type

dynamic_types
this comma separated list points to directories in which MPC will search for Perl modules to
implement additional MPC project types, base projects or template files. This setting can be
used to augment or replace functionality in MPC. For each suitable directory found, it will
add a modules include path for Perl to find modules, add a config include path to locate base
projects and a template include path to find MPC templates.

includes similar to the -include command line option, it adds the list of comma separated paths to the
MPC include search paths.

logging if this setting contains info=1, informational messages will be printed. If it contains
warn=1, warning messages will be printed. If it contains diag=1, diagnostic messages will be
printed. If it contains debug=1, debug messages will be printed. And lastly, if it contains
detail=1, detail messages will be printed. If it contains none of these, mpc-ace will not
print out any information or warnings when processing projects or workspaces. Errors are
always printed if any are encountered.

verbose_ordering
if this is set, mwc-ace will warn the user about references to projects in the after keyword
that have not been processed

ENVIRONMENT VARIABLES
The following environment variable could affect mwc-ace and mpc-ace:

MPC_DEPENDENCY_COMBINED_STATIC_LIBRARY
see the help on -static parameter above

MPC_GHS_UNIX
this environment variable is only meaningful when generating the ghs project files. By
default, the ghs type assumes that it is for Windows. If this is not the case, set this
environment variable prior to running MPC
