Made the Requirements information its own major section and moved it
between the "Getting Started Quickly" and "Getting Started Slowly" sections. :) Removed some of the nit-picky requirements information (i.e. GNU tar and GNU zip). Attempted to compact the requirements information so that it is less scary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9290 91177308-0d34-0410-b5e6-96231b3b80d8

First, LLVM comes in two pieces. The first piece is the LLVM suite. This

low level virtual machine. It also contains a test suite that can be used

|

The second piece is the GCC front end. This component provides a version

of GCC that compiles C and C++ code into LLVM bytecode. Currently, the

Before you begin to use the LLVM system, review the requirements given

below. This may save you some trouble by knowing ahead of time what
|

hardware and software you will need.

LLVM is known to work on the following platforms:
|

<ul>
|
||||
<li> Linux on x86 (Pentium and above)
|

|
||||
<li> Approximately 760 MB of Free Disk Space

LLVM <i>may</i> compile on other platforms. The LLVM utilities should work
|
||||
on other platforms, so it should be possible to generate and produce LLVM
|
||||
bytecode on unsupported platforms (although bytecode generated on one
|
||||
platform may not work on another platform). However, the code generators
|
||||
and Just-In-Time (JIT) compilers only generate SparcV9 or x86 machine code.

Unpacking the distribution requires the following tools:

<dl compact>

<dt>
|

<A href="http://www.gnu.org/software/gzip/gzip.html">GNU Zip (gzip)</A>
|

<dt><A href="http://www.gnu.org/software/tar/tar.html">GNU Tar</A>
|
||||
<dd>
|

These tools are needed to uncompress and unarchive the software.
|

Regular Solaris <tt>tar</tt> may work for unpacking the TAR archive but

is untested.

|

Compiling LLVM requires that you have several different software packages
|
||||
installed:
|
||||
|
||||
<dl compact>
|
||||
<dt> <A href="http://gcc.gnu.org">GCC</A>
|
||||
<dd>
|
||||
The GNU Compiler Collection must be installed with C and C++ language
|
||||
support. GCC 3.2.x works, and GCC 3.x is generally supported.
|
||||
|
||||
<p>
|
||||
Note that we currently do not support any other C++ compiler.
|
||||
</p>
|
||||
|
||||
<dt> <A href="http://savannah.gnu.org/projects/make">GNU Make</A>
|
||||
<dd>
|
||||
The LLVM build system relies upon GNU Make extensions. Therefore, you
|
||||
will need GNU Make (sometimes known as gmake) to build LLVM.
|
||||
<p>
|
||||
|
||||
<dt> <A href="http://www.gnu.org/software/flex">Flex</A>
|
||||
and
|
||||
<A href="http://www.gnu.org/software/bison/bison.html">Bison</A>
|
||||
<dd>
|
||||
The LLVM source code is built using flex and bison. You will not be
|
||||
able to configure and compile LLVM without them.
|
||||
<p>
|
||||
|
||||
<dt> <A href="http://savannah.gnu.org/projects/m4">GNU M4</A>
|
||||
<dd>
|
||||
If you are installing Bison on your machine for the first time, you
|
||||
will need GNU M4 (version 1.4 or higher).
|
||||
</dl>
|
||||
|
||||
<p>
|
||||
There are some additional tools that you may want to have when working with
|
||||
LLVM:
|
||||
</p>
|
||||
|
||||
<ul>
|
||||
<li><A href="http://www.gnu.org/software/autoconf">GNU Autoconf</A>
|
||||
<li><A href="http://savannah.gnu.org/projects/m4">GNU M4</A>
|
||||
<p>
|
||||
If you want to make changes to the configure scripts, you will need
|
||||
GNU autoconf (2.53 or higher), and consequently, GNU M4 (version 1.4
|
||||
or higher).
|
||||

|
||||
|

<li><A href="http://www.codesourcery.com/qm/qmtest">QMTest</A>
|
||||
<li><A href="http://www.python.org">Python</A>
|
||||
<p>
|
||||
In order to run the tests in the LLVM test suite, you will need QMTest and
|
||||
a version of the Python interpreter that works with QMTest.

The LLVM suite <i>may</i> compile on other platforms, but it is not
|

guaranteed to do so. If compilation is successful, the LLVM utilities
|
||||
should be able to assemble, disassemble, analyze, and optimize LLVM
|

bytecode. Code generation should work as well, although the generated
|
||||
native code may not work on your platform.
|
||||
<p>
|

The GCC front end is not very portable at the moment. If you want to get
|

it to work on another platform, you can always request
|

<a href="mailto:llvm-request@zion.cs.uiuc.edu">a copy of the source</a>
