=============
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 >= 3.4. 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/>. Also Python version >= 2.6 is
-required.
+from <http://pkg-config.freedesktop.org/>. Also, Python 3 is required.
To build the GiNaC tutorial and reference manual the doxygen utility
(it can be downloaded from http://www.stack.nl/~dimitri/doxygen) and
TeX are necessary.
Known to work with:
- - Linux on x86 and x86_64 using
- - GCC 3.4, 4.0, 4.1, 4.2, 4.3.x (x >= 1), 4.4, 4.5, 4.6, and 4.9
- - Clang 2.8
- - Windows on x86 using GCC 3.4 (MinGW)
+ - Linux on x86 and x86_64 using
+ - GCC 4.8, 4.9, 5.1, 5.2, 5.3, and 6.1
+ - Clang 3.5, 3.6, 3.7, 3.8
Known not to work with:
- Clang 2.7 and earlier due to poor C++ support.
- - GCC 4.3.0 due to the compiler bug,
- see <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35548>.
- - GCC 2.96 or earlier because proper exception and standard library support
- is missing there.
+ - GCC < 4.6.0 due to missing C++-11 support
If you install from git, you also need GNU autoconf (>=2.59), automake (>=1.8),
-libtool (>= 1.5), python (>= 2.5), bison (>= 2.3), flex (>= 2.5.33) to be installed.
+libtool (>= 1.5), python3, 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 on optimization levels. To give you
-a rough idea of what you have to expect the following table may be helpful.
-It was measured on an Athlon X2/3GHz with 4Gb of RAM.
-
-step | GCC optimization | comment
- | -O1 | -O2 |
---------------+---------+---------+----------------------------------------
-make | ~1m | ~2m | shared library only (--disable-static),
- | | | parallel compilation (MAKEFLAGS=-j2)
-make check | ~6m | ~6m | largely due to compilation
+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.
To install from git
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:
