PREREQUISITES
=============
-GiNaC requires the CLN library by Bruno Haible, available from either
-one of the following FTP-sites:
- * <ftp://ftp.santafe.edu/pub/gnu/>,
- * <ftp://ftp.ilog.fr/pub/Users/haible/gnu/> or
- * <ftp://ftpthep.physik.uni-mainz.de/pub/gnu/>.
-You will also need a decent ANSI-compliant C++-compiler. We use
-`post-EGCS' GCC, i.e GCC >= 2.95 for development so if you have a
-different compiler you are on your own. Note that you may have to use
-the same compiler you compiled CLN with because of differing
-name-mangling schemes.
-
-Optionally, GiNaC may work together with Masaharu Goto's free C++
-interpreter Cint. You may obtain it from
- * <ftp://root.cern.ch/root/>.
-Install it by following the instructions included in Cint's
-distribution before trying to compile GiNaC-cint. (See section
-`Working with the Cint C++ interpreter' below.)

INSTALLATION
$ make
$ make check
[become root if necessary]
- $ make install
+ # make install
Known to work with:
- - Linux/x86, EGCS-1.1.x and GCC 2-95.x
+ - Linux on x86, Alpha and Sparc using GCC 3.0.x, 3.1 and 3.2.
Known not to work with:
- - GCC 2.7.x or earlier because proper exception support is missing there.
+ - GCC 2.96 or earlier because proper exception and standard library support
+ is missing there.
The "configure" script can be given a number of options to enable and
disable various features. For a complete list, type:
Large amounts of memory (>128MB) will be required by the compiler,
also depending on optimization. To give you a rough idea of what you
have to expect the following table may be helpful. It was measured on

COMMON PROBLEMS
Problems with CLN
-----------------
-You should use at least CLN V1.0.3, since during the development of
+You should use at least CLN-1.1, since during the development of
GiNaC various bugs have been discovered and fixed in earlier versions.
-To protect you, the "configure" script checks for a feature that was
-added in V1.0.3 so it won't continue with earlier versions anyhow.
Please install CLN properly on your system before continuing with
GiNaC.
doesn't supply such packages, go to <ftp://ftp.gnu.org/gnu/readline/>
and compile it yourself.
+Problems with missing standard header files
+-------------------------------------------
-Working with the Cint C++ interpreter
-=====================================
-
-Please see <http://root.cern.ch/root/Cint.html> to learn about Cint
-and install it prior to installing ginaccint. For the interpreter-
-compiler `makecint' to work properly, the Makefiles need to know where
-Cint has its system directory. This is usually done by exporting
-$CINTSYSDIR to point to the proper place. With GiNaC you may either
-try to export that variable and type
- $ ./configure --with-cint
-or specify it directly on the command line by saying
- $ ./configure --with-cint=/my/path/to/cintsysdir
-This variable does not have to be exported for running the installed
-binary: since the actual program is started by a launcher that sets it.
-Enjoy!
-
-Here is an overview to gives you an idea if you can expect GiNaC-cint
-to compile, install and work properly:
-
- Cint version | how it works
---------------+----------------------------------------------------------
- < 5.14.39 | `VERBOTEN' by license (please bite your favorite lawyer)
- < 5.14.39,40 | compiles but does not feel happy at all (inconsistent!)
- 5.14.41 | tested on egcs 1.1.1, gcc 2.95.2: only minor weirdnesses
- 5.14.44 | G__cpp_ginaccint.C needs manual fixes, doesn't work well
+Building GiNaC requires many standard header files. If you get a
+configure error complaining about such missing files your compiler and
+library are probably not up to date enough and it's no worth
+continuing.
