This is LattE integrale "for tea, too", a source code distribution of 
of LattE integrale and 4ti2 with all prerequisite libraries.

All software included in this distribution is free software; with some
caveats regarding LiDIA (see notes at the bottom). 


To build:

Prerequisites:

 * On Linux, nothing special.  

 * On Mac OS X, you need the XCode command line tools.

 * On Windows, install Cygwin and, beyond the standard packages, also
   packages "gcc", "g++", "make", "m4".

 * On Solaris, a version of gcc.

Make sure you have unpacked this distribution in a build directory
without a space in its name (this is to work around a limitation in
libtool).  (Note that on Windows, the user's home directory usually
has a space in its name.  Use instead, for example, /cygdrive/c/latte;
this corresponds to C:\LATTE.)

If you checked out this distribution via git, you first need to
generate the autotools build system as follows:

   ./autogen.sh

Optionally, if you have Maple, make sure that the directory where the
command-line executable of Maple lives ("maple" or, on Windows,
"cmaple.exe") is in your path:

   export PATH="/path/to/maple/directory:$PATH"

Then type in the shell:

   ./configure
   make

When the build process is finished, you will find all binaries in the
directory 

   dest/bin

If supported on your operating system, LattE is built "relocatable",
that is, you can move the dest/ subdirectory to a different place, and
everything should still work.  Alternatively, you can pass the
--prefix=/SOME/ABSOLUTE/DIRECTORY/NAME option to ./configure to give a
directory where LattE integrale should be installed instead of the
dest/ subdirectory.  For example:

   ./configure --prefix=/usr/local

By default, all programs are linked statically.  To build and use
shared libraries, invoke configure with --enable-shared.  This does
not work on all platform (for example, it does not work on Cygwin.)
Also, note that shared library builds are not completely relocatable:
LattE itself (in most modes) works, but other binaries (4ti2, cddlib,
...) don't.

I hope this LattE integrale distribution works for you.  Compatibility
notes can be found below.  Please report any failures, so we can
improve the distribution and also LattE integrale itself.

Enjoy!

Information for building packages for Linux distributions, Sage packages, etc.:

  Do not attempt to use this "distribution" package.  Rather build
  separate packages for LattE integrale and each of the bundled
  libraries.  We use modified versions of some upstream libraries;
  consider using our versions instead of upstream for your distribution. 

  cddlib: 

    Our version adds a few more build system changes on top of the
    non-upstream version distributed as a Sage package.

  LiDIA: 

    Upstream development has ceased; download URL was defunct as of
    August 2013.  Our version is derived from an experimental Sage
    package.  Our version adds a number of build fixes for current gcc
    version.  It is also available from:

        https://github.com/mkoeppe/LiDIA

  4ti2: 

    We used to include special releases of 4ti2 only released through
    this "Latte for tea, too" distribution and not announced on 4ti2.
    As of version 1.6, we are back to standard upstream.

Release 1.6 of LattE integrale (or a prerelease of it) has
successfully built on:

  * Mac OS X (Intel) 10.8.4 with XCode 4.6.3 (GCC 4.2.1)

  * Mac OS X (Intel) 10.8.4 with GCC 4.8.1 from Fink

  * Mac OS X (PPC)

  * Ubuntu Linux 12.04.2 LTS (x86_64) with GCC 4.6.3-1ubuntu5

  * Ubuntu Linux 11.10 "Oneiric Ocelot" (x86_64) with GCC 4.6.1-9ubuntu3

  * Gentoo Linux with GCC 4.6

  * Windows XP with Cygwin of July 2013

  * Solaris 10 (UltraSPARC) in 32 bit mode with GCC 4.5.1


A previous release of LattE "for tea, too" has successfully
built on:

  * Solaris 9 on SPARC in 32-bit mode with GCC 3.3.2

  * Solaris 9 on SPARC in 32-bit mode and 64-bit mode with GCC 4.1.1 and 4.2.0

    By default, 32-bit binaries are created on Solaris.
    To compile in 64-bit mode on Solaris, use: 

    ./configure CC="gcc -m64 -mptr64" CXX="g++ -m64 -mptr64"

  * Debian GNU/Linux on x86 with GCC 3.3.2

  * Fedora Core 3 Linux on x86_64 (AMD Opteron) with GCC 3.4.2

  * Fedora Core 2 Linux on x86 with GCC 3.3.3 20040412 (Red Hat Linux 3.3.3-7)

  * Debian GNU/Linux 3.0 on Alpha with GCC 3.0.4

It fails to build on:

  * Non-GCC compilers, like all Forte/Workshop/Sun Studio compilers on
    Solaris).

    The reason is that the Forte/Workshop/Sun Studio compilers do not
    like the C++ part of GMP.  Use GCC instead.

  * Solaris 9 on SPARC in 64-bit mode with GCC 3.3.2

    Use 32-bit mode or a newer GCC version; for instance GCC 4.1.1.

  * Fedora Core 3 Linux on x86_64 (AMD Opteron) with GCC 4.0.0
    20041019 (Red Hat 4.0.0-0.8).

    Compiling NTL causes an internal compiler error.  Use a different
    GCC version instead.

  * Debian GNU/Linux 3.0 on Alpha with GCC 2.95.4

    This compiler cannot build CDD+.  Use a newer GCC version.


				*  *  *

Some of the C++ libraries are very picky about the version of the C++
compiler.  Older ones or newer ones might not work.  To ensure a
specific compiler is used, type:

   ./configure CC=/path/to/your/gcc CXX=/path/to/your/g++
   make

The pickiest of all C++ libraries used is LiDIA.  As a last resort,
you can turn off using LiDIA:

   ./configure --disable-lidia
   make

Likewise, you can turn off using the optional library 4ti2:

   ./configure --disable-4ti2
   make

If you have a multiprocessor machine, be sure to use it to shorten the
compile time by parallelizing the build:  For instance, on a
4-processor machine, use

   make -j4

(Because of parallelization bugs in some of the Makefiles (not ours!),
the parallelized build might get stuck; in this case, repeat the "make
-j4" until the build is finished.)

The status of LiDIA is unclear.  It comes with a "free for
non-commercial purposes" license, but developers stated that they have
agreed to release it as free software under the GPL.  See
