<h1 align="center">Building egcs-1.0.2</h1>

<p>Now that egcs is configured, you are ready to build the compiler and
runtime libraries.

<p>We <b>highly</b> recommend that egcs be built using gnu-make; other
versions make work, then again they might not.  To be safe build with gnu-make.

<p><b>Building a native compiler</b>
<p>For a native build issue the command "make bootstrap".  This will build
the entire egcs compiler system, which includes the following steps:

<ul>
  <li> Build host tools necessary to build the compiler such as texinfo, bison,
  gperf.<p>

  <li> Build target tools for use by the compiler such as gas, gld, and
  binutils.<p>

  <li> Perform a 3-stage bootstrap of the compiler.<p>

  <li> Perform a comparison test of the stage2 and stage3 compilers.<p>

  <li> Build runtime libraries using the stage3 compiler from the previous
  step.<p>
</ul>

<p>If you are short on disk space you might consider "make bootstrap-lean"
instead.  This is identical to "make bootstrap" except that object files
from the stage1 and stage2 of the 3-stage bootstrap of the compiler are
deleted as soon as they are no longer needed.

<p><b>Building a cross compiler</b>

<p> We recommend reading the
<a href="ftp://ftp.cygnus.com/pub/embedded/crossgcc/FAQ-0.8.1">
crossgcc FAQ</a> for information about building cross compilers.

<p>For a cross build, issue the command "make cross", which performs the
following steps:
<ul>
  <li> Build host tools necessary to build the compiler such as texinfo, bison,
  gperf.<p>

  <li> Build target tools for use by the compiler such as gas, gld, and
  binutils.<p>

  <li> Build the compiler (single stage only).<p>

  <li> Build runtime libraries using the compiler from the previous
  step.<p>
</ul>

<p>Note that if an error occurs in any step the make process will exit.
