6.3 Building Mozart

Now we can get to the real thing. Retrieve the sources from the CVS:

cvs -d cvs.mozart-oz.org:/services/mozart/CVS get mozart cvs -d cvs.mozart-oz.org:/services/mozart/CVS get mozart-stdlib

(specify -r mozart-1-3-0-fixes to get the fixes branch). See http://www.mozart-oz.org/download/view.cgi?action=cvs for details about anonymous CVS. Let mozart be the directory created by the first cvs get command and stdlib the one created by the second.

Environment Variables

We need to start with a clean PATH, which in particular must not contain any Mozart installation. The following works on my system:

export PATH=/usr/bin:/bin:emacs/bin:/cygdrive/c/WINNT/system32:/cygdrive/c/WINNT

Furthermore, we want to tell the configuration scripts where we placed our Windows DLLs:

export windlldir=packages/dlls

The Fun Part

Say we want to install Mozart into directory install. Then we can configure, build, and install Mozart as follows:

cd build mkdir mozart-build cd mozart-build CXX=g++ mozart/configure \ --prefix=install \ --with-inc-dir=packages/include \ --with-lib-dir=packages/lib \ --with-tcl=packages \ --with-tk=packages \ --disable-contrib-compat \ make bootstrap make install

oztool (which is required for building some of the contributions) does not work if given a cygwin symbolic link to the executable it should run. Currently cygwin has c++ as a symbolic link to g++. We get around this by setting CXX=g++ during the configure process, which will then choose g++ as our default C++ compiler.

We will build the standard library in a different directory, but it will be installed in the same one where Mozart is. This is specified in during the configuration. Then we can configure, build, and install Mozart as follows:

cd build mkdir stdlib-build cd stdlib-build ../stdlib/configure --prefix=install make make install

A note on the configuration options: Most of these should be clear, they simply convey to the configuration scripts the knowledge of where we placed our packages. More information on configuration options can be found in Chapter 7. We have to disable the compat contrib because it does not build in bootstrap mode (yet). This is why we have to build it separately once we have our installed system:

cd build mkdir compat-build cd compat-build export PATH=install/bin:$PATH CXX=g++ mozart/contrib/compat/configure --with-global-oz --prefix=install mkdir share cp build/mozart-build/share/Makefile.boot share make make install

And yeah, verily, thus and so - we're done.

Using Mozart

To use Mozart, you simply have to extend your PATH:

export PATH=install/bin:$PATH

Then you can start oz, ozc and so on, as you would expect.
