libtool
-Then run
+Getting started
+---------------
+
+If these preliminaries are met, you should run the script
+
+ ./autogen.sh
- ./autogen.sh DUNEDIR
+which calls the GNU autoconf/automake to create a ./configure-script
+and the Makefiles. Most probably you'll have to provide where to find
+the DUNE-files by
-where DUNEDIR is the (absolute or relative) path of the dune/-directory.
+ ./autogen.sh --with-dune=PATH
-The directory is needed because autogen.sh needs access to the tests
-stored in DUNEDIR/m4
+where PATH is a directory with a dune/-subdirectory inside (this
+convention is needed to keep the #include-syntax consistent even when
+the headers are installed into /usr/include/dune later).
-Now call
- ./configure --with-dune=DIR
+Passing options to ./configure
+------------------------------
-where DIR is the directory _above_ dune/. If you want to include third
-party packages check
+autogen.sh also calls the newly created configure-script to
+conveniently pass on options about the used compiler. Thus you'll have
+to provide autogen.sh any options you want configure to get, e.g.
- ./configure --help
+ ./autogen.sh --with-dune=... --with-albert=... --without-x
-for options on how to include Albert, Grape, UG, ...
-If configure checked your system without problems you can use
+Choosing the compiler and the options
+-------------------------------------
- make
+The selection of the compiler works as follows: if --gnu or --intel is
+passed to autogen it reads the content of gcc.opts or icc.opts to get
+the default compiler flags. With the option --optim you can switch the
+compiler-specific optimization parameters on.
-to build all examples.
+If you want to change the compiler options to your favourites you can
+either
+
+ - adapt the appropriate .opts-file and rerun autogen.sh. Please don't
+ commit this changed file to CVS if you're not sure if the options
+ work for everybody.
+
+ - copy an existing .opts-file to a new name, change the options and
+ use
+
+ ./autogen.sh --opts=my.opts
+
+
+More info
+---------
+
+See
+
+ ./autogen.sh --help
+
+and (if it exists)
+
+ ./configure --help
+
+for further options.
+
+
+The full build-system is described in the dune/doc/Buildsystem (not in
+duneapps/doc!)
