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
