ozmake is a tool for building Mozart-based projects and for creating and installing Mozart packages. It was inspired by the Unix tools make and rpm, but is much, much simpler, is specialized for Mozart-based software development and deployment, and transparently supports all platforms on which Mozart has been ported. ozmake must currently be invoked from a shell, but it will eventually acquire additionally an optional, user-friendly graphical interface.

In the following, we write meta variables between angle brackets, e.g. <PREFIX> or <URI as cache path>

General Options

-v, --verbose
print out more tracing information that the default. By supplying this option twice, you will sometimes get even more information.
-q, --quiet
suppress all tracing and feedback information
-n, --just-print
perform a dry run, i.e. just print what would happen without actually performing the actions
do not recurse into subdirectories
default: true
automatically determine build-time and install-time (run-time) dependencies. Currently, this is only supported for Oz sources by looking at import and require sections.

What you should remember here, is that -vn is your friend. Add -vn at the end of any ozmake invocation, and it will tell you in great detail what the command would do, without actually doing it.

Directories and URLs

default: ~/.oz
root of private installation area
default: current directory
default directory for other options below

-V <VERSION>, --packageversion=<VERSION>
this option is respected by --extract and --install. When --extract is given a MOGUL id and downloads the corresponding package from the MOGUL archive, it will look precisely for the given <VERSION> of the package. --install will simply check that the package to be installed really has this <VERSION>.

ozmake --list --package=<MOGUL>
list info for the installed package indentified by mogul id <MOGUL>
default: 70
assume a line with of N characters


ozmake --config=put <OPTIONS>
record the given <OPTIONS> in ozmake's configuration database, and use them as defaults in subsequent invocations of ozmake unless explicitly overriden on the command line. For example: ozmake --config=put --prefix=/usr/local/oz saves /usr/local/oz as the default value for option --prefix
ozmake --config=delete <OPT1> ... <OPTn>
deletes some entries from the configuration database. For example: ozmake --config=delete prefix removes the default for --prefix from the configuration database
ozmake --config=list
lists the contents of ozmake's configuration database

the argument to --config can be abbreviated to any non-ambiguous prefix


If you choose to contribute packages to the MOGUL archive, ozmake --mogul=<ACTION> simplifies your task. It makes it easy for you to maintain a database of your contributions and to export them so that the MOGUL librarian may automatically find them. In fact, the simplest way is to use ozmake --publish which will take take care of all defails for you.

ozmake --mogul=put
update the user's database of own mogul contributions with the data for this contribution (in local directory)
ozmake --mogul=put --package=<PKG>
same as above, but using the package <PKG> explicitly given
ozmake --mogul=delete <MOG1> ... <MOGn>
remove the entries with mogul ids <MOG1> through <MOGn> from the user's database of own contribution
ozmake --mogul=delete
remove entry for current contribution
ozmake --mogul=list
show the recorded data for all entries in the user's database of own mogul contributions
ozmake --mogul=list <MOG1> ... <MOGn>
show the recorded data for entries <MOG1> through <MOGn> in the user's database of own mogul contributions
ozmake --mogul=export
write all necessary mogul entries for the user's own mogul contributions. These are the entries which will be read by the MOGUL librarian to automatically assemble the full MOGUL database.

The data for your contributions need to be made available to the MOGUL librarian on the WEB. You want to just update a local directory with your contributions, but, in order for the MOGUL librarian to find them, these directories must also be available through URLs on the WEB. Here are some options that allow you to control this correspondance, and for which you should set default using ozmake --config=put

<MOGULDIR> is a directory which is also available on the WEB through url <MOGULURL>. <MOGULDIR> is intended as a root directory in which sub-directories for packages, documentation, and mogul entries will be found.

For those who really enjoy pain, ozmake has of course many options to shoot yourself in the foot. In the options below <ID> stands for the filename version of the package's mogul id (basically replace slashes by dashes). You can control where packages, their documentation and mogul database entries and stored and made available using the options below:

default: <MOGULDIR>/pkg/<ID>/
default: <MOGULURL>/pkg/<ID>/
default: <MOGULDIR>/doc/<ID>/
default: <MOGULURL>/doc/<ID>/
default: <MOGULDIR>/db/<ID>/
default: <MOGULURL>/db/<ID>/

Your contributions should all have mogul ids which are below the mogul id which you where granted for your section of the mogul database. For convenience, ozmake will attempt to guess the root mogul id of your section as soon as there are entries in your database of your own contributions. However, it is much preferable to tell ozmake about it using:


and to set it using ozmake --config=put --mogulrootid=<ROOTID>


The makefile contains a single Oz record which describes the project and should normally be placed in a file called makefile.oz. A makefile typically looks like this:

          lib : ['Foo.ozf']
          uri : 'x-ozlib://mylib'
          mogul : 'mogul:/denys/lib-foo')

stating explicitly that there is one library target, namely the functor Foo.ozf, and that it should installed at URI:


and implicitly that it should be compiled from the Oz source file Foo.oz. When you invoke ozmake --install, the mogul feature serves to uniquely identify this package and the files it contributes in the ozmake database of installed packages.

There are many more features which can occur in the makefile and they are all optional. If you omit all the features, you only get the defaults and you don't even need a makefile. All values, suchs as files, should be given as virtual string; atoms are recommended except for features blurb, info_text and info_html, where strings are recommended.

          bin      : [ FILES... ]
          lib      : [ FILES... ]
          doc      : [ FILES... ]
          src      : [ FILES... ]
          depends  :
             o( FILE : [ FILES... ]
          rules    :
             o( FILE : TOOL(FILE)
          clean     : [ GLOB... ]
          veryclean : [ GLOB... ]
          uri       : URI
          mogul     : MOGUL
          author    : [ AUTHORS... ]
          released  : DATE
          blurb     : TEXT
          info_text : TEXT
          info_html : TEXT
          subdirs   : [ DIRS... ]
          requires  : [ MOGUL... ]
          categories: [ CATEGORY... ]
          version   : VERSION
          provides  : [ FILES... ]

Features bin, lib and doc list targets to be installed in <BINDIR>, <LIBDIR> and <DOCDIR> respectively. bin targets should be executable functors, i.e. they should end with extension .exe. lib targets are typically compiled functors i.e. ending with extension .ozf, but could also be native functors, i.e. ending with extension .so, or simply data files. doc targets are documentation files.


ozmake knows how to build targets by looking at the target's extension:

is an executable functor and is created from Foo.ozf
is a compiled functor and is created from Foo.oz
is a compiled C++ file and is created from Foo.cc
is a native functor and is created from Foo.o
is a C++ source file
is a C++ header file

Note that these are abstract targets. In particular, Foo.so really denotes the file Foo.so-<PLATFORM> where <PLATFORM> identifies the architecture and operating system where the package is built; for example: linux-i486. Also, when a bin target Foo.exe is installed, it is installed both as <BINDIR>/Foo.exe and <BINDIR>/Foo so that it can be invoked as Foo on both Windows and Unix platforms.

It is imperative that you respect the conventional use of extensions described here: ozmake permits no variation and supports no other extensions.


ozmake has built-in rules for building files. Occasionally, you may want to override the default rule for one or more targets. This is done with feature rule which contains a record mapping target to rule:


the rule may also have a list of options:


The tools supported by ozmake are ozc (Oz compiler), ozl (Oz linker), cc (C++ compiler), ld (C++ linker). The default rules are:

        'Foo.exe' : ozl('Foo.ozf' [executable])
        'Foo.ozf' : ozc('Foo.oz')
        'Foo.o'   : cc('Foo.cc')
        'Foo.so'  : ld('Foo.o')

The tools support the following options:

make the result executable
define macro S. Same as -DS on the command line
make the result executable
Similar to the usual C++ compiler option -IDIR. DIR is a virtual string
Similar to the usual C++ compiler option -DMAC. MAC is a virtual string
Similar to the usual C++ linker option -lDIR. DIR is a virtual string

You might want to specify a rule to create a pre-linked library:

        'Utils.ozf' : ozl('Foo.ozf')

or to create a non-prelinked executable:

        'Foo.exe' : ozc('Foo.oz' [executable])


ozmake automatically determines whether targets needed to be rebuilt, e.g. because they are missing or if some source file needed to create them has been modified. The rules are used to determine dependencies between files. Sometimes this is insufficient e.g. because you use tool ozl (dependencies on imports), or \insert in an Oz file, or #include in a C++ file. In this case you can specify additional dependencies using feature depends which is a record mapping targets to list of dependencies:

        TARGET : [ FILES... ]

For example:

        'Foo.o' : [ 'Foo.hh' 'Baz.hh' ]


        'Foo.exe' : [ 'Lib1.ozf' 'Lib2.ozf' ]


During development, it is often convenient to be able to easily remove all junk and compiled files to obtain again a clean project directory. This is supported by ozmake --clean and ozmake --veryclean; the latter also implies the former. Files to be removed are specified by glob patterns where ? matches any 1 character and * matches a sequence of 0 or more characters. All files in BUILDDIR matching one such pattern is removed. There are built-in patterns, but ou can override them with features clean and veryclean which should be lists of glob patterns. For example the default clean glob patterns are:

        clean : [ "*~" "*.ozf" "*.o" "*.so-*" "*.exe" ]

Package Related Features


feature uri indicates the URI where to install lib targets. For example:

        uri : 'x-ozlib://mylib/XML'

states that all lib targets (e.g. Foo.ozf) will be installed under this URI so that they can also be imported from it, i.e.:

       import MyFoo at 'x-ozlib://mylib/XML/Foo.ozf'


feature mogul is the mogul id uniquely identifying this package. It is used to identify the package in the database of installed packages, to create/publish the package, and to install its documention files.


feature author is a virtual string or list of virtual string resp. identifying the author or authors of the package. It is recommended to identify authors by their mogul id, however is is also possible to simply give their names. For example, the recommended way is:

        author : 'mogul:/duchier'

but the following is also possible:

        author : 'Denys Duchier'


feature released is a virtual string specifying the date and time of release in the following format:

        released : "YYYY-MM-DD-HH:MM:SS"

time is optional. An appropriate release date using the currentdate and time is automatically inserted when invoking ozmake --create or ozmake --publish.


feature blurb contains a very short piece of text describing the package. This text should be just one line and is intended to be used as a title when the package is published in the mogul archive.


feature info_text contains a plain text description of the package. This is intended to be used as an abstract on the presentation page for the package in the mogul archive. It should be brief and informative, but should not attempt to document the package.


feature info_html is similar to info_text but contains HTML rather than plain text.


feature src indicates which targets should be considered source, i.e. in particular non-buildable. All targets mentioned in src should be mentioned in bin, lib, or doc too. The point of src is to support distributing packages with pre-built targets and without giving out the corresponding sources. You should not do this with native functors since they are platform dependent and not portable, but it can be a convenient means of distributing prebuilt Oz libraries. For example:

          lib : [ 'Foo.ozf' ]
          src : [ 'Foo.ozf' ]
          uri : 'x-ozlib://mylib'
          mogul : 'mogul:/myname/foolib')

is a makefile for a package that distribute the precompiled Foo.ozf, but does not also distribute its source Foo.oz. Normally, when you build a package it simply checks that the src files are present but will not attempt to build them. If you have the sources, you can force building the src targets if necessary using --fullbuild.


feature subdirs is a list of bare filenames representing subdirectories of the project. By default, when necessary, ozmake will recurse into these subdirectories. It is expected that each subdirectory should provide its own makefile. The mogul id is automatically inherited to subdirectories and the uri is automatically extended by appending the name of the subdirectory: thus submakefiles can be simpler since they don't need to be concerned with package-level features.


feature requires is a list of module URIs or package MOGUL ids. These represent the external dependencies of the package. They are not yet used, but eventually ozmake will be able to use them to automate the recursive installation of other packages required by the one you are interested in.


feature categories is a list of MOGUL categories to help categorize this package in the MOGUL archive.


feature version is used to provide a version string. This is a string that consist of integers separated by single dots, e.g. "2" or "3.1.7".


feature provides is used to override the default information about what the package provides, normally automatically computed from the bin and lib targets: it should be a list which contains a subset of these targets. The provides feature of a makefile does not override or otherwise affect its submakefiles: each makefile should separately override if it so desires. To state that a makefile does not officially provide any functors or executable application, you would add:

        provides : nil
You should use the provides feature when your package contains both official public functors as well as purely implementational functors that are not part of the official public interface and should not be mentioned as provided by the package.


Authors should really be referred to by mogul ids denoting mogul entries that describe them. In order to make this easier, a makefile.oz may also contain a contact feature which is either a record describing a person, or a list of such records.

You should not have a contact feature in every makefile. Rather, the contact feature is usually intended for makefiles that only have a contact feature, i.e. whose only purpose is to create mogul entries for the corresponding persons. Here is an example of such a makefile:

           contact :
                 mogul : 'mogul:/duchier/denys'
                 name  : 'Denys Duchier'
                 email : 'duchier@ps.uni-sb.de'
                 www   : 'http://www.ps.uni-sb.de/~duchier/'))

You can invoke ozmake --publish on such a makefile to contribute the corresponding mogul database entries
