=============
GiNaC requires the CLN library by Bruno Haible installed on your system.
-It is available from <ftp://ftpthep.physik.uni-mainz.de/pub/gnu/>.
+It is available from <https://www.ginac.de/CLN/>.
-You will also need a decent ANSI-compliant C++-compiler. We recommend the
-C++ compiler from the GNU compiler collection, GCC >= 3.0. If you have a
+You will also need a decent ISO C++-11 compiler. We recommend the C++
+compiler from the GNU compiler collection, GCC >= 4.8. If you have a
different or older 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.
The pkg-config utility is required for configuration, it can be downloaded
-from <http://pkg-config.freedesktop.org/>.

To build the GiNaC tutorial and reference manual the doxygen utility

Known to work with:
- - Linux on x86, Alpha and Sparc using GCC 3.x and 4.0.
+ - Linux on x86 and x86_64 using
+ - GCC 4.8, 4.9, 5.x, 6.x, 7.x, 8.x, and 9.x
+ - Clang 3.5, 3.6, 3.7, 3.8, 6.x, 7.x, 8.x, and 9.x
Known not to work with:
- - GCC 2.96 or earlier because proper exception and standard library support
- is missing there.
+ - Clang 2.7 and earlier due to poor C++ support.
+ - GCC < 4.6.0 due to missing C++-11 support
-If you install from CVS, you also need GNU autoconf (>=2.59), automake (>=1.7),
-libtool (>= 1.5), bison (>= 2.3), flex (>= 2.5.33) to be installed.

INSTALLATION
============
-To install from a source .tar.bz2 distribution:
+To install from an unpacked source .tar.bz2 distribution:
$ ./configure
$ make
More detailed installation instructions can be found in the documentation,
in the doc/ directory.
-The time the "make" step takes depends heavily on optimization levels. 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 an Athlon/800MHz with
-"enough" memory:
+The time to build the library depends to a large degree on optimization levels.
+Using the default high optimization, 'make' takes a few minutes on a fast
+machine and 'make check' takes some more minutes. You can speed this up with a
+parallel build with 'make -j2' or higher, depending on the number of available
+CPU cores.
-step | GCC optimization | comment
- | -O1 | -O2 |
---------------+---------+---------+----------------------------------------
-make | ~6m | ~8m | shared and static library
-make check | ~8m | ~12m | largely due to compilation

-To install from CVS
+To install from git
===================
First, download the code:
-
- $ cvs -d :pserver:anoncvs@cvs.ginac.de:/home/cvs/GiNaC login
- [enter "anoncvs" as the password]
- $ cvs -d :pserver:anoncvs@cvs.ginac.de:/home/cvs/GiNaC co GiNaC
- $ cd GiNaC
+ $ git clone git://www.ginac.de/ginac.git ginac
+ $ cd ginac
Secondly, make sure all required software is installed. This is *really*
important step. If some package is missing, the `configure' script might
be misgenerated, see e.g. this discussion:
-<http://www.ginac.de/pipermail/ginac-list/2007-November/001263.html>

Problems with CLN
-----------------
-You should use at least CLN-1.1, since during the development of GiNaC
+You should use at least CLN-1.2.2, since during the development of GiNaC
various bugs have been discovered and fixed in earlier versions. Please
install CLN properly on your system before continuing with GiNaC.
Problems building ginsh
-----------------------
-The most common reason why this doesn't succeed is the absence of GNU
-libreadline and/or the corresponding header files. Depending on what your
-system/distribution is, you will have to install a package called
-libreadline and maybe libreadline-dev. If your system's vendor doesn't
-supply such packages, go to <ftp://ftp.gnu.org/gnu/readline/> and compile
-it yourself. Note that non-GNU versions of libreadline (in particular
+The GiNaC interactive shell, ginsh, makes use of GNU readline to provide
+command line editing and history. If readline library and/or headers are
+missing on your system, the configure script will issue a warning. In this
+case you have two options:
+
+1) (the easiest) If you don't intend to use ginsh (i.e. if you need GiNaC
+library to compile some piece of software), ignore it. ginsh builds just
+fine without readline (obviously, it won't support the command line history
+and editing).
+
+2) Install GNU readline and run the configure script once again. Depending on
+what your system/distribution is, you will have to install a package called
+libreadline and libreadline-dev (or readline-devel). If your system's vendor
+doesn't supply such packages, go to <ftp://ftp.gnu.org/gnu/readline/> and
+compile it yourself. Note that non-GNU versions of libreadline (in particular
one shipped with Mac OS X) are not supported at the moment.
