 <h1 align="center">Building egcs-1.0.3</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.
